APPENDIX 4.
CATALOGUE OF THE BIRDS OF THE NORTH-EAST COAST OF AUSTRALIA AND TORRES STRAIT.

Lists exhibiting the occurrence of Australian Birds in particular districts are instructive, as showing the range of species over the various parts of an extensive district, and as bearing upon, and to my mind confirming, to a certain extent, the views of those geologists who consider Australia to have formerly appeared as a cluster of three or four islands, subsequently connected since the tertiary epoch so as to form what may now be considered as a continent. With the kind assistance in determining the species of Mr. Gould, who has elsewhere published similar lists* of the birds of other parts of Australia, the annexed Catalogue has been made out. All the species contained therein have passed under my own observation, and I have distributed them in three columns; the first includes that portion of the north-east coast of Australia and its islands included between the Tropic of Capricorn and latitude 17 degrees 45 minutes south, or the parallel of the bottom of the Gulf of Carpentaria; the second comprises the remainder of the north-east coast as far to the northward as Cape York; and the third is devoted to the islands of Torres Strait, from Raine Islet to Bramble Cay. The species marked with an ? (query) are those which are probably local varieties, representatives of southern birds, showing slight differences in size, etc., yet not decided enough to be of specific value.

APPENDIX 5.
ON THE MOLLUSCA COLLECTED BY MR. MACGILLIVRAY DURING THE VOYAGE OF THE RATTLESNAKE, BY PROFESSOR EDWARD FORBES, F.R.S.

1. ON THE BATHYMETRICAL DISTRIBUTION OF MARINE TESTACEA ON THE EASTERN COAST OF AUSTRALIA.

As in every instance the exact locality, depth and character of habitat of species of Mollusc taken were carefully noted of at the time of capture, much more valuable information elucidating the distribution of shellfish in the Australian seas has been collected during this expedition than was ever before obtained. Whilst new species are usually sought after by collectors with eagerness, the habits and range of the commoner or less conspicuous forms are passed over without observation.* Hence every note on the habitat and mode of life of marine creatures from the southern hemisphere becomes of no small value. Indeed, there is no information more desirable at this time for the illustration of geological phenomena, than such as may throw light on the distribution in range and depth of the creatures inhabiting the sea of the Tropics, and those living around the coasts of Australia and New Zealand. The following notes will serve to record the more prominent facts bearing upon the Bathymetrical distribution of the Testacea collected on the northern coast of Australia, at Port Essington, and on the eastern coast from Cape York to Bass Strait, including the northern ports of Van Diemen's Land.

(*Footnote. An extensive collection of landshells was made at Madeira. They proved on examination to be all known species, including several of the rarer forms, and not a few of those discovered by the Reverend Mr. Lowe. They were compared with Madeiran specimens by Mr. Vernon Wollaston. When the Rattlesnake touched at the Azores on the return voyage, a few landshells were collected at Fayal. Among them was the Helix barbula, an Asturian species, Helix pauperata, and Bulimus variatus, Madeiran or Canarian forms. A considerable number of marine and terrestrial Testacea were procured at Rio de Janeiro, not a few of them new and of great interest. Terebratula rosea was dredged off Rio in thirteen fathoms water, on a coarse sandy bottom. Collections were also made at the Cape of Good Hope, at Mauritius and in the Falkland Isles. The radiata were gathered with as much care and their habitats recorded with as much attention as the Mollusca.)

It may here be remarked that the Molluscan fauna of the seas of North Australia and of the north-east coast from Cape York southwards to Sandy Cape, belongs to the great Indo-Pacific province, a zoological region extending from the east coast of Africa (from Port Natal or a little above, northwards to Suez) to Easter Island in the Pacific. But south of Sandy Cape and onwards to Van Diemen's Land (and apparently including New Zealand) we have a distinct (East)Australian province, marked by a peculiar fauna in many respects, representative of the Senegal, and perhaps also Lusitanian regions of the North Atlantic.

Proceeding in descending order we may first remark on the:

SHELLS OF SALT MARSHES.

As in the Northern hemisphere, Melampus or Convolvulus is the genus represented in such localities. Thus Auricula australis prevails in salt marshes at Brisbane Water, and an allied species in similar places in New Zealand. In both instances we find this form accompanied by members of a curious genus characteristic of the Australian province--Ampullacera, the Ampullacera quoyana being the Brisbane Water species, and A. avellana, that of New Zealand. In the latter case an Assiminea is its companion. A very curious fact noted during the expedition was the presence of a Unio living within the influence of salt water, in the River Brisbane.

SHELLS INHABIT MUD, ETC. AMONG MANGROVES.

These belong to the Indo-Pacific province. Some are found on the mangroves themselves. Such are the Littorina scabra, on the trunks and branches of mangroves among islets in Trinity Bay; a Phasianella inhabiting the trunks and branches of Rhizophora at the Percy Isles; a Littorina on the leaves of Aigaeceras fragrans at Port Curtis, Auricula angulata, and rugulata on the trunks of mangroves at Port Essington, and Monodonta viridis on their roots at Night Island; a new and very beautiful Ostrea was found on the roots of mangroves among Low Islets in Trinity Bay. In the last-named locality a Cytherea inhabited the mud around their roots. At the Three Islets several new species of Melampus, a Nerita and a Cyrena lived in a like habitat, and at Port Essington Cerithium kieneri, was found in the same situation. The fine Cyrena cyrenoides lives among the roots of mangroves in the Louisiade Archipelago.

LITTORAL ZONE.

Of the many living Gasteropoda taken in this region, very few are new species. Of Patelloid forms we have a new Fissurella and Parmophorus convexus at Port Dalrymple, accompanied by Haliotis naevosa, and species of Patella and Siphonaria. In the more tropical regions, Haliotis asinina and varia, another and distinct Patella, two Fissurellae and a Scutella were collected. Of convolute shells the littoral species gathered were all Indo-Pacific and inhabitants of mostly the coral-reef region, such as Cypraea arabica, annulus, isabella, errones and oryza, Conus magus, arenatus, achatinus, etc., Oliva cruentata, tremulina and ericinus, those of the last-named genus often living in sand. Bulla cylindrica occurred in sandy pools on the reef at Claremont Isles. Of Volutes, V. turneri lives on coral blocks at Port Essington, and V. undulata partially buried in sandbanks at Port Dalrymple. Conus maculosus is an inhabitant of the last-named locality. The Mitras found in the Littoral zone were all on the north-east coast, and well-known Indo-Pacific forms. A new Murex was taken on mud at Port Curtis. Fasciolaria coronata, Fusus alveolatus, and Triton verrucosus were found on the reefs at Port Dalrymple. Many species of Nassa, all known forms, were collected, mostly on mud in the Littoral zone, chiefly in the north-eastern province. Phos cyanostoma lives on muddy sand in the Trinity Bay islets, where also in similar situations is Terebra maculata and Pyramidella maculosa. Pyramidella auriscati is a littoral shell among the reefs of the Claremont Isles. Several Purpurae were taken on reefs and rocks at low-water; among them was P. textiliosa, a Port Dalrymple species. A Quoya lives on rocks being high-water mark in Lizard Island. Several Terebrae, including T. crenulata dimidiata and affinis, inhabit muddy sand among Pipon's Islets. The well-known Strombus luhuanus lives on sand among the reefs at Eagle Island. A Cerithium inhabits mud-flats at Port Molle and Pipon's Islets. Of the holostomatous gasteropods inhabiting the Littoral zone, the Naticae, mostly well-known species, were taken in sandy localities on the north-east coast, and the Neritae in the same province, mostly on rocks or reefs. Littorina pyramidalis and mauritiana are inhabitants of the rocky headlands of Broken Bay; other forms were collected at Port Curtis and at Port Dalrymple. At the last-named locality, Turbo undulatus, a new Risella, Monodonta constricta and buccata, and Trochus reticularis were taken on reefs. Littoral species of the same genera occurred on the north-east coast. A New Rissoa was found under stones at Night Island. Turbo squamosus and Trochus lentiginosus are inhabitants of the shore at Port Essington. In Broken Bay species of Bankivia and Scalaria were collected, cast dead on the shore.

The Acephala found living in the Littoral zone of the south-east Australian province were Cleidotherus chamoides, under rocks at low-water in Port Jackson; Mytilus erosus on the mud of zostera flats at Port Dalrymple, several species of Venus, Tapes, Cytherea in similar localities; Arca globata in the same habitat at Brisbane; Arca fuscata in reefs at Port Dalrymple; a new Tellina on mud at Port Phillip; another with Donax epidermia in sand at Broken Bay, and Clavagella australis on rocks at low-water, Port Jackson. Species of Pectunculus, Nucula, Pandora, Anatinella, Venus, Tellina (decussata and deltoidalis) and Mesodesma are thrown dead on the shores.

In the north and north-east Australian province the living littoral Acephala are Solens of which two new species were taken at Port Essington, Anomia australis, Anatina olerina, and another, new, in the same locality; species of Mytilus, Meleagrina and Pinna, Ostrea and Pecten (pyxidatus) Lima fragilis and squamosa, Hippopus and Tridacna, the former detached on coral reefs, the latter embedded in the coral, Corbis fimbriatus in sand among coral reefs; species of Venus, Cytherea, Circe, and Tapes in mud, Artemis sculpta at Port Essington on sand, Lucinae on sand or reefs, Crassatella on mudflats at Port Curtis, where Cypricardia vellicata occupies the fissures of rocks with Carditae; several species of Cardium in mud or sand, including C. fragum, C. subrugosum, and C. unedo; Sanguinolaria rugosa at Dunk Island; species of Mesodesma in sand, and Mactrae and Tellinae in mud; a new Psammobia at Port Essington as also a new Pholas that bores into coral. Other species, members of the same genera, are cast on shore dead.

REGION OF WEEDS EQUIVALENT TO THE LAMINARIAN REGION OF THE EUROPEAN SEAS.

Some seventeen or eighteen localities in this Bathymetrical province were explored by means of the dredge, varying in depth from one to seventeen fathoms. In the south-east Australian province the principal Gasteropoda procured were Bulla brevis, at Port Jackson, in 6 fathoms; Cyprea oryza, at Port Phillip, in 5 fathoms; Calyptraea connata, in 6 fathoms, Port Jackson, with Nassa suturalis, and another, a new Terebra, Monotigma casta, Mitra sordida, a Marginella, a Columbella, and Struthiolaria oblita. A Phasianella was dredged in from 3 to 5 fathoms on sandy mud, at Port Phillip, with Elenchus rutilus, Marginella fornicata, and Cerithium granarium. In the North-east Australian province, a different set of shells was dredged in similar depths, such as a Sigaretus, possibly new, Fissurella calyculata, Mitra obeliscus, a Turritella, a Murex, Columbella versicolor, and a new species off Cape York, Ranella pulchella, new, several Nassae, Phos senticosa and blainvillei, and sculptilis, in 3 and 5 fathoms, off Cape York; Strombus campbelli, in mud off Cape Upstart; Cerithium obeliscus, and a new species of the genus Obeliscus. In the deeper localities Cypraea fimbriata occurred, dead, off Cape Capricorn; and two species of Ranella, one being R. pusilla, in 17 fathoms, off the Percy Isles. The univalves dredged among the Louisiade Islands in this region of depth were mostly known forms, such as Conus betulinus, Oliva sanguinolenta, Mitra exasperata, Terebra maculata, consors and labiata; these were all taken in less than six fathoms water.

The bivalves of this region were but few. In the South Australian province species of Mactra, Psammobia, Venus, Tapes and Pecten, all peculiar, were taken. This is the region of the peculiar genus Myadora, of which five species were dredged on sand in 6 fathoms at Port Jackson, along with Myochama anomioides, Trigonia margaritacea, Lima bullata, and Cardium radiatum. In the North-east Australian province we have species of Donax, Mactra and Corbula, all apparently new, from the shallower localities; Corbula tunicata, Pectunculus tenuicostatus, and another, from 8 to 11 fathoms, off Cumberland Islands; species of Arca, Pectunculus, Avicula, Pecten, Venus, Circe, Cardium, Cardita, and Erycina, mostly new, from 15 to 17 fathoms in a sandy and shelly bottom off Cape Capricorn.

CORALLINE ZONE.

Some dredgings in both North and South-eastern provinces, in depths between twenty-seven and forty-five fathoms, give a slight idea of the fauna of this important region. In the South-eastern province we find in forty and forty-five fathoms on a muddy bottom in Bass Strait, Turritella sinuata, Trochus nebulosus, a Pleurotoma, an Emarginula, a Dentalium, two species of Cardita, a Cypricardia, a Venus, a Nucula, and Pectunculus holosericeus. In the North-eastern province we find off Cumberland Island in 27 fathoms, also on a muddy bottom, species of Murex, Nassa, Turritella, Ranella pusilla, a Fusus, Cancellaria antiquata, a Terebra, two Dentalia, a Natica, a Terebellum, a Scalaria, a Cardium, a Venus, a Nucula, a Pecten, and a Spondylus.

It is evident from the comparative paucity of undescribed species procured in the Littoral zone and the large proportion of new or doubtful forms among those taken by the dredge, that a rich harvest has yet to be reaped in the deeper regions of the southern seas. In the lower zones, however, just as much as in the upper, the distinctions of province are maintained. The explanation of this complete separation of the South-eastern marine fauna of Australia from that of the North-eastern or Indo-Pacific portion, may be explained by reference to the distribution of currents along the Australian shores. In both, as in the Bathymetrical regions of the South Atlantic, the Testacea of the depths are generally smaller and less brightly coloured than those inhabiting the shallows.

During this voyage notes of the habitats of considerably more than a thousand species of Mollusca and Echinodermata were carefully registered.

2. ENUMERATION OF TERRESTRIAL PULMONIFEROUS MOLLUSCA AS YET NOTICED IN AUSTRALIA.

The following Catalogue is founded on the monograph of Helicidae by Dr. Pfeiffer. To the species therein described are added certain new ones, announced by Pfeiffer since the publication of his work, and others, recorded for the first time in this volume. It will be seen that a great part of the Australian land-shells is as yet unfigured. The exact localities of not a few have to be determined; a precise record was kept of the place and circumstances under with each was found during the voyage of the Rattlesnake. From all we yet know the genus Helix is fairly represented in New Holland, and presents some very remarkable and peculiar forms; Bulimus has but few, and those (with the sole exception of B. atomatus) not remarkable Australian members; a single Pupa, closely resembling one of our commonest European species, is the only recorded Australian one; and a very remarkable addition to the terrestrial conchology of the southern hemisphere has been made in a Balea of a type unlike any other member of the genus.

3. DESCRIPTIONS OF S0ME NEW SPECIES OF SHELLS, DISCOVERED DURING THE VOYAGE OF THE RATTLESNAKE.

Relu brumeriensis. Tab. 2 fig. 1. a, b.

Testa imperforata, globosa-conoidea, crassa, laevigata (sub lente granulato-striata) alba, ad aperturam nigra; spira obtusa, conoidea; anfractus 4, convexiusculi, rapide accrescentes, ultimus basi subcompressus; apertura per-obliqua, oblonga, intus alba; peristoma late reflexum, nigrum. Diam. maj. 28, min. 23, alt. 23, millem. (Mus. Brit.)

This remarkable shell resembles a dwarf H. haemastoma in shape; it is of a porcelain white except at the aperture, which has a broad reflexed lip of a deep brown-black hue, both within and without. It is a very interesting species, indicative of the Indian affinities of the New Guinea fauna. A single specimen was taken in August 1849, on a breadfruit tree in Brumer Island, South-East coast of New Guinea.

Helix divisa. Tab. 2 fig. 5. a, b.

Testa obtecte perforata, lenticulari-depressa, orbicularis, carinata, crassiuscula, superne fulva, radiato-striata, minutissime granulata, carina acuta, superne subcrenulata, basi convexa, nitidissima, griseo-albida, radiatim substriata ad umbilicum declivens; spira convexiuscula; anfractus 5, planulati; apertura angulato-lunaris, intus margaritacea; peristoma simplex, basi incrassatum, ad columellam expansiusculum. Diam. maj. 23, min. 20, alt. 11, mill. (Mus. Brit.)

A Helix of the Caracolla section, allied to the C. panayensis of Broderip. Found on the ground at the roots of trees, in the South-East Island of the Louisiade Archipelago.

Helix louisiadensis. Tab. i. fig. 8. a, b.

Testa imperforata, globoso-turbinata, solidiuscula, sub lente rugosa, albida, fasciis variis purpureo-fuscis ornata; spira conoidea, rubescens; anfrac. 5 convexiusculi, ultimus magnus, paululum deflexus; apertura ovata, intus nitide livida, peristoma expansum, reflexum, sordide violaceum, margine externo sinuato, columellari incrassato, dilatato, subsulcato. Diam. maj. 26, min. 21, alt. 20, mill. (Mus. Brit.)

This remarkable snail has a tendency towards a trochi-form contour. The ground colour appears as a white band on the body whorl marking its most prominent portion just below the centre. The sinuation of the outer lip and impression of the whorl behind the peristome, give a slightly ringent aspect to the mouth. It is very distinct from any known species; its affinities are more with Australian than with Philippine forms. It was taken on a tree in the South-East Island of the Louisiade Archipelago.

Helix yulei. Tab. n. fig. 6. a, b.

Testa profunde umbilicata, depresso-globosa, solida, striata, sub epidermide fulvo-alba, fasciis castaneis cingulata; spira sub-depressa, obtusa; anfractus 6 convexiusculi; apertura subcircularis; peristoma nigrum, expansum, margine basali reflexo, columellari dilatato, umbilicum subtegente. Diam. maj. 37, min. 27, alt. 25, mill. (Mus. Brit.)

This handsome species is of a rich fulvous hue, with dark chestnut bands and a deep chestnut umbilicus, partly covered by the reflexion of the nearly black lip. It is allied to the H. incei, a well known north-east Australian species. It was found in hollow trees, and under logs and stones at Port Molle, in the same region.

Helix macgillivrayi. Tab. 3 fig. 1.

Testa imperforata, trochiformis, carinata, striis minutis spiralibus ornata, pallide fusco-carnea, punctis nigris albo-occellatis sparsa; spira conica; anfractus 6 planati, ultimus carinatus, basi subplanatus; apertura oblique oblonga, intus brunnea, margine externo bisinuato; peristoma album, incrassatum, infra reflexum; columella basi rufescens. Diam. maj. 23, min. 19, alt. 21, mill. (Mus. Brit. and Geol.)

Of all Australian Helices, this is perhaps the most curious. Its outline and aspect are singularly like those of a Trochus of the Ziziphinus group. The colour is also very singular, being a yellowish flesh hue deepening on the base to rich brownish-yellow, and speckled irregularly with minute black dots which are areolated with white, the white ring being largest on the side towards the mouth. The fine striae that encircle the body are also very curious. The outer lip of the aperture seems as if it had been dented in two places. Behind the white thickened peristome, intemaily is a dark brown band, which is seen through the shell as a dark blackish green stripe. The edge of the outer lip declines to join the body whorl a little below the keel. It was found on trunks and branches of trees in the Frankland Isles.

Helix dunkiensis. Tab. 2 fig. 7. a, b.

Testa umbilicata, depresso-globosa, subcarinata, solida, radiato striata et subtilissime granulata, flavida; spira late depressa, convexiuscula, apice obtusa; anfractus 6 convexiusculi, ultimo obsolete carinato; apertura lunaris, intus alba; peristoma superne rectum, margine basali margine columellarique sub-reflexis, umbilicus profundus, conspicuus, vix obtectus. Diam. maj. 24, min. 21, alt. 16, mill. (Mus. Brit.)

This snail strikingly resembles some Illyrian forms. It has affinities with H. coriaria, a species said to be from Ceylon. It was taken under stones and about roots of trees in Dunk Island, on the North-East coast of Australia.

Helix franklandiensis. Tab. 2 fig. 2. a, b.

Testa aperte-umbilicata, tumido-depressa, nitidissima, superne radiatim striata, cornea, fasciis angustis transversis distantibus fulvis; spira angusta; anfractus 5 planiusculi, ultimus rotundatus, antice vix descendentes; apertura rotundata; peristoma simplex, vix acutum, rectum, margine columellari non reflexo. Diam. maj. 26, min. 21, alt. 14 mill. (Mus. Brit.)

This beautiful snail is of a brightly shining yellowish or greenish horn colour. The whorls of its spire are small, but the body whorl, whilst preserving a wide diameter throughout, gradually increases in trumpet-like manner to the round mouth. It belongs to the same group with H. olivetorum and H. nitida, and is allied to the Australian H. ptycomphala. It occurs about the roots of trees in the Frankland and Lizard Islands.

Helix iuloidea. Tab. 2 fig. 4. a, b, c, d.

Testa late et perspective umbilicata, orbicularis, superne depressa seu subconcava, rufo-cornea, regulariter costulata; anfractus 4 1/2 convexiusculi, ultimus tumidus, rotundatus; apertura lunaris; peristoma simplex, acutum. Diam. maj. 4 1/2, min. 4, alt. 3 mill. (Mus. Brit. & Geol.)

This curious little snail, resembling a rolled-up Iulus, and reminding us of our own H. rotundata and its allies, was found under a stone at Port Molle.

Helix inconspicua. Tab. 2 fig. 3. a, b, c.

Testa perforata, depresso-convexa, laevigata, nitidiuscula, pallide cornea, basi subcompressa; anfractus 6, planiusculi; spira obtusa; apertura lunaris; peristoma rectum, simplex, margine columellari reflexo: umbilicus minutus, subobtectus. Diam. maj. 8--min. 7--alt. 5 mill. (Mus. Brit.)

A very inconspicuous ordinary-looking little shell, its upper surface recalling the aspect of H. alliaria but with more convexity and no lustre, and its base that of H. crystallina. It was found, apparently gregarious, under dead leaves in an islet in Trinity Bay.

Balea australis. Tab. 2 fig. 9. a, b.

Testa dextrorsa, rimata, subcylindracea, turrita, decollata, dense capillaceo-costulata, corneo-lutea, maculis obscuris flavidis; sutura impressa; anfractus 11, convexiusculi; apertura pyriformis, columella triplicata, plica inferior maxima, conspicua, elevata, acuta, spiralis; peristoma continuum, solutum. Long. 18--Diam. 4--Apert 4 mill. (Mus. Brit. & Geol.)

This very remarkable shell, the first of its genus discovered in Australia, differs from all its congeners. It has exactly the aspect of a Clausilia, but the mouth is not furnished with a clausium. It was found under stones at Port Molle.

Pupina grandis. Tab. 2 fig. 10. a, b, c, d.

Testa ovato-subcylindrica, superne laevigata, inferne rugulosa, sordide-rufa; spira obtusa; anfractus 6, secundus tumidus, obliquus, ultimus super aperturam planatus; apertura rotundata; peristoma laete aurantiacum, rimatum, crassum, dorsaliter canaliculatum, infra columellari, profunde sinuatum et in canali contorto excavatum; canalis alter minutus ad partem superiorem et externam aperturae; callus columellaris expansus, appressus. Long. 30, Diam. 15, Apert. 7 mill. (Mus. Brit. & Geol.).

This, the giant of its genus, is perhaps the most remarkable land-shell discovered during the voyage. It differs from all other Pupinae in having an unpolished surface. It was found in the South-East Island of the Louisiade Archipelago, under dead leaves chiefly about the roots of trees.

Pupina thomsoni. Tab. 3 fig. 2. a, b.

Testa ovata, polita, nitidissima, translucens, hyalina, solidiuscula; spira obtusa; anfractus 5, duo ultimi majores; apertura orbicularis; peristoma album, crassum, solutum, canalibus duobus interruptum; canalis superior ad partem superiorem et externam aperturae, inferior major, basalis, marginibus disjunctis et in dorsum anfractus prolongatis. Long. 7 1/2, diam. 4 1/2, apert. 2 mill. (Mus. Brit.)

This remarkable and beautiful little Pupina is most nearly allied to the P. bilinguis of Cape York. From that species (which is larger) it differs, however, very materially, most especially in the position of the inferior or basal canal of the aperture which is here placed like the canal of a whelk, but in P. bilinguis is very small and placed high up, cutting as it were the columella. The curious manner in which the margins of the canals are prolonged on the back of the body whorl like parallel and somewhat diverging walls is also a singular feature of this species, which is dedicated to Dr. Thomson, surgeon of the Rattlesnake, and an excellent botanist. It was found among dead leaves at the roots of trees in Fitzroy Island.

Helicina stanleyi. Tab. 3 fig. 4. a, b.

Testa lenticularis, superne inferneque convexa, orbicularis, acute carinata, fusco-carnea, spiraliter striata; spira obtusa; anfractus 4 1/2 leviter convexiusculi; basis imperforata, centraliter laevigata, alba; apertura oblique sublunata, angulata; peristoma simplex, tenue. Diam. maj. 6 1/2, min. 6, alt. 5 mill. (Mus. Brit.)

Found on the leaves and trunks of trees and bushes (especially Scaevola koenigii) in the Duchateau Isles, Louisiade Archipelago. Dedicated to the late Captain Owen Stanley, R.N.

Helicina louisiadensis. Tab. 3 fig. 5. a, b.

Testa depresso-globosa, superne inferneque convexa, orbicularis, obsolete sub-angulata, pallide aurantiaca, sub lente spiraliter striata; spira obtusa; anfractus 4 1/2, vix convexiusculi; basis imperforata, centraliter sub-impressa; apertura lunata, inferne subangulata; peristoma incrassatum, aurantiacum, reflexum. Diam. maj. 4 1/2, min. 4, alt. 3 mill. (Mus. Brit.)

On Round Island in Coral Haven, Louisiade Archipelago, under stones. This pretty little Helicina is nearly allied to some Philippine species.

Helicina gouldiana. Tab. 3 fig. 3. a, b.

Testa depresso-globosa, superne sub-conica, orbicularis, obsolete subangulata, flava seu rufa, spiraliter striata; spira prominens; anfractus 5, planati; basis imperforata; apertura sub-lunata, inferne angulata; peristoma incrassatum, subreflexum, album. Diam. maj. 6, min. 5 1/4, alt. 4 1/2 mill. (Mus. Brit.)

Under the bark of Mimusops kaukii, in the Two Isles, on the North-East coast of Australia. Dedicated to the indefatigable illustrator of Australian ornithology.

Ranella pulchella. Tab. 3 fig. 6. a, b.

Testa turrita, utroque alata, acute-caudata, alba; anfractus tumidi, spiraliter striati, longitudinaliter noduloso-costati, costis crebris, lateraliter varicosi, varices compressi, aliformes, crenulati, striati, ad margines crenati; apertura ovato-rotunda, inferne longe-caudata; peristoma solutum. Long. 20, diam. 14, apert. 4 mill. (Mus. Brit.)

This beautiful shell was dredged in from 8 to 11 fathoms water, on a bottom of sand and shells between Cumberland Island 1.i, and Point Slade (Latitude 21 degrees South Longitude 149 degrees 20 minutes East).

The spiral striae that cross its whorls are grouped in pairs; their interstices are raised, and more or less finely crenulated; as they pass out on the expanded and wing-like varices they diverge, and the lobe-like projections that scallop the margins of the wings are separated from each other by each pair of diverging striae. The fine ribs that cross the whorls are not present on the wings, nor on the back; they are nodulated at their decussation with the raised striae. The wing-like varices of the whorls overlap each other alternately on each side of the shell. The only species to which it has affinity is the R. pulchra.

Scalaria jukesiana. Tab. 3 fig. 7.

Testa lanceolato-turrita, gracilis, alba, laevis, nitida, longitudinaliter costata, costis lamellosis, reflexis, simplicibus, nnmerosis (in ult. anfrac. 20); anfractus 11, tumidi; sutura profunde impressa; varices nulli; apertura orbicularis, margine laevi. Long. 13, Diam. max. 14, apert 3 mill. (Mus. Brit.)

This beautiful little Scalaria is deserving of particular notice on account of the analogy and representation which it exhibits with the S. clathratulus of the seas of the Northern Hemisphere. It is dedicated to the author of the Voyage of the Fly.

New Genus--MACGILLIVRAYIA, Forbes.

Shell spiral, dextral, globular, thin, corneous, transparent (in the only known species smooth or marked by obscure lines of growth) imperforate; spire not produced (with a sinistral nucleus ?). Aperture oblong, entire, angulated below; peristome incomplete, thin, even-edged.

Operculum semicircular, horny, thin, composed of concentric layers with faint traces of a spiral structure at the centro-lateral nucleus, which is on the columellar side; from it there runs a strait rib or process continued nearly to the outer margin, and indicated externally by a depression or groove.

Animal ample, provided with four very long and rather broad linear rugose (or ciliated ?) tentacula; mantle produced into a long siphon; foot very large, expanded, truncate in front, bearing the operculum near its posterior extremity, but not accompanied by filamentous processes or lobes. A float. (Mus. Brit. and Geol.)

This very remarkable mollusk was taken in the towing net off Cape Byron, on the east coast of Australia, in latitude 28 degrees 40 minutes South, fifteen miles from the shore. It was floating and was apparently gregarious. Mr. Macgillivray states that it is furnished with a float in the manner of Ianthina. The largest specimens measure rather less than two lines in diameter. The shell is of a yellow horn colour (as is also the operculum) thin and transparent. It bears a striking resemblance to our much more minute Jeffreysia opalina. The four tentacula and the form of the very peculiar operculum also seem to indicate considerable affinity with the genus Jeffreysia of Alder, and an examination of the remains of the tongue extracted from a dried specimen showed an arrangement and form of the lingual denticles very closely resembling that exhibited by Jeffreysia. On the other hand, the very distinct and long siphonal tube delineated in Mr. Macgillivray's drawing, taken when the animal was alive, would seem to refer this genus to some family probably near to Cancellaridae. It is certainly entirely distinct in every respect from any known Gasteropod. It is a form of very great interest to the geologist, for in it we see the nearest representation of certain palaeozoic (especially Lower Silurian) univalves hitherto referred to Littorina, but which, judging from their associates and the indications afforded by the strata in which they are found, were assuredly either inhabitants of deep water or floaters in a great ocean like the Pacific.

I have dedicated this most interesting creature to my friend Mr. Macgillivray, its discoverer, whose researches have been productive of so much new and valuable contributions to all departments of zoological science.

I have named the species M. pelagica. Tab. 3 fig. 8. a, b, c, d. (Mus. Brit. and Geol.)

New Genus--CHELETROPIS, Forbes.

Shell spiral, turbinate, dextral, imperforate, spirally ridged or double-keeled and transversely wrinkled; spire prominent, its nucleus sinistral; aperture ovate, canaliculated below, its outer margin furnished with two claw-like lobes, the one central and formed by a prolongation of the margin between the keels of the body whorl, the other smaUer and nearer the canal; peristome thickened, reflexed, forming a conspicuous margin.

Operculum none ?

Animal unknown, but certainly floating, and probably pteropodous. This I infer from its habits, and from the analogy of the shell with Spirialis. (Mus. Brit. & Geol.)

The only known species, C. huxleyi (dedicated to Mr. Huxley, Assistant Surgeon of the Rattlesnake, and now eminent for the admirable anatomical researches among marine invertebrata which he conducted during the voyage) is very minute, being not more than the 1/24th of an inch in diameter. It is translucent and of a brownish-white hue. Its aspect is that of a Turbo in miniature. The whorls are tumid, the spire prominent; the body whorl is belted by two prominent keels, one of which is continued on the whorls of the spire: between, above, and below these keels are transverse membranous raised ridges, which in the central division of the body whorl are curved forwards. This curvature corresponds with the projection of the curious incurved claw-like lobe that proceeds from thc central portion of the lower lip. Towards the base of the aperture is a second and similar but smaller lobe, below which is the short but broad and well-marked canal. The entire lip is marginated by the thickened and reflected peristome. I believe this curious floating shell will throw some light on the true nature and habits of several palaeozoic types. It was taken in the towing net, gregarious, in the sea off Cape Howe, the south-east corner of Australia. Tab. 3 fig. 9. a, b.
