MAMMALIA. 
TRIBE I. 
NATIVES OF THE OLD CONTINENT. 
(Simise Catarrhini, Geoffroy.) 
The animals of this tribe have five grinders, crowned with 
blunt tubercles in each jaw—nostrils divided only by a thin sep¬ 
tum—tails, either wanting or short; some few long, but not 
prehensile. They inhabit Africa, India, and its islands. 
Sub-Genus ]. — Orangs Proper—Without callosities on the 
hinder parts. 
Genus 1.— Troglodytes. — Geoffroy. 
Generic Character. — Facial angle 50 degrees; rio cheek 
pouches, tail, nor callosity on the hinder parts; arms short; 
superciliary ridges distinct. The canine teeth are somewhat 
projecting, and are close to the incisory and grinding teeth, like 
those of the human species;—the head is rounded, and the muz¬ 
zle slightly projecting.

This animal makes the nearest approach to man of all other 
quadrupeds, both in face, form, and internal organization. The 
fur is black, the arms are of a moderate length, the mouth and 
ears are large. He differs from the Orang-Outang, in wanting 
the intermaxillary bone, and in the last joint of his great toe 
being perfect. He has the round ligament of the thigh-bone, 
which fits him more than the Orang-Outang for assuming the 
upright posture. The body is covered with long, coarse, and 
thinly scattered hairs; the face is naked, brown, the cheeks 
only having hairs: the abdomen is nearly smooth. Inhabits 
Africa, at Angola and Congo. No perfect specimen of this Ape 
has yet reached Europe.
