One or two genera of Cheilostomata may be mistaken for Cyclostomata. In case of doubt, 7 et seq. must be worked through.

Certain varieties of adherent species occasionally assume an erect form.

For Celleporella (colony minute: orifice tubular), see 41 et seq.

Rhynchozoon (see No. 61), in which the primary orifice becomes much obscured by the development of a large mucro, is placed in this section.
