Notes.
Specimens of Anthropopithecus niger and Gorilla gorilla, in the Derby Museum, Liverpool, in which the permanent teeth have not yet developed, have the premaxillary suture quite obliterated.
The deformity known in the human skull as acrocephaly, which occurs in all races of men, and is due to the too early ossification of certain of its sutures, has been found in the Chimpanzee.

Living and fossil.
A form of S. mitratus.
Midas rufiventer, said to be from Mexico by Dr. Gray, is now believed to be Amazonian. Mr. Bates' statement that Hapale pygmæa is found in Mexico (vol. i., p. 136) is erroneous, and no species of Marmoset is known from the Mexican Province.
Chrysothrix entomophaga is stated by me (vol. i., p. 156) to inhabit Central America. The Squirrel-Monkey of Panama, however, is C. œrstedi, and C. entomophaga must be restricted to the Brazilian Sub-region (cf. Alston, Biol. Centr. Amer. Mamm., p. 16).
