728 Proceedings of the Asiatic Society, [June, 



Supplementary Report of the Curator of the Zoological Department. 



I beg to present the following memorandum on the species of Quadrumana 

 at present in the Society's Museum. 



The species of Primates, Lin., divide into what may be termed the Cheiro- 

 poda and Cheiroptera, the former of which comprehends the subjects of this 

 Report. The group first subdivides into what may be designated the An- 

 thropida and the Lemnria. 



The Anthropida falls into two primary divisions, respectively peculiar to 

 the Old World and to the New World. These are the Catarhini and Platy- 

 rhini of M. Geoffroy St. Hilaire. The former, among other characteristic 

 distinctions, have constantly but two false molars on each side of both jaws : 

 the latter have, as invariably, three. 



The Catarhini next fall in to three well marked sub-groups. — 1. That com- 

 prising the Human genus and the three genera of Apes, which have sundry 

 anatomical peculiarities in common. — 2. That composed of the Baboons and 

 ordinary Monkeys of the Old World, with a simple stomach, and which are 

 furnished with cheek-pouches. — 3. That consisting of those numerous 

 long-tailed Monkeys of the Old World which have a sacculated stomach, and 

 no cheek-pouches. 



The general appellation of Quadrumana applies to all of the Cheiropoda 

 excepting Man. Our collection contains the following specimens, commencing 

 with the Apes. 



Troglodytes niger, Geoffroy. Of the Chimpanzee, we have a stuffed young 

 male, standing 22§ inches high, forwarded by Mr. A. Bartlett, of London.* 



Pithecus, Geoffroy. The Orang-utans. Five stuffed specimens, besides 

 skeletons, of all ages, from very young to fu" ,vn. Firstly, we have the 

 mounted skin (deprived of one hand and one foot, which are preserved in 

 spirit in the museum of the Linnasan Society of London), of the celebrated 

 large adult (but not old) male procured in Sumatra by Capt. Cornfoot, who 

 presented it to the Society, and which is described by Dr. Clark Abel in the 

 15th Volume of the ' Asiatic Researches,' and further noticed by myself in 

 Vol. X, p. 837, of the Society's Journal. Secondly, the mounted skin and 

 skeleton of a female (of the race termed P. morio by Prof. Owen), which 

 lived 12 years in Calcutta in the possession of J. Apcar, Esq., who presented 

 it when dead to the Society, and was informed that the animal was six months 

 old at the time it fell into his possession. In this specimen the dentition had

 History of the Malayan Peninsula,' reprinted by Mr. H. E. Strickland in Aim. Mag.
