however, is no objection—the same variation is frequently 
observed in the human subject. | 
The arms of the remaining Ourangs reach only to the knee. They 
have no forehead, and the cranium retreats from the crest of the 
eye-brow. The name of CurmpansEs might be exclusively applied 
to them. 
S. troglodytes, L. (The Chimpansé)(1) is covered with black 
or brown hair. Could any reliance be placed on the accounts 
of travellers, this animal must be equal or superior to man 
in stature, but no part of it hitherto seen in Europe indicates 
this extraordinary size. It inhabits Guinea and Congo, lives 
in troops, constructs huts of leaves and sticks, arms itself with 
clubs and stones, and thus repulses men and elephants; pur- 
sues and abducts, as is said, negro women, &c. Naturalists 
have generally confounded it with the Ourang-Outang. When 
domesticated he soon learns to walk, sit, and eat like a man. 
We now separate the Gibbons from the Ourangs. 
Hirosates, Illig. 
"The Gibbons have the long arms of the true Ourangs, and the 
low forehead of the Chimpansé, along with the callous buttocks of 
the Guenons, differing however from the latter.in having no tail 
* or cheek-pouch. » They all inhabit the most remote parts of India. 
S. lars L.; Buff. XIV, 2; Onko, Fred. Cuv. pl. 5 and 6, (The 
Black Gibbon) is covered with coarse black hairs, ae has a 
whitish circle round his face. 
' H. agilis, Fred. Cuy. pl. 3 and 4; Petit Gibbon of Buffon, 
XIV, 3, (The Brown Gibbon) is brown—the circle round the 
face is of a pale red; the lower part of the back is of the same 
colour. The young are of a uniform yellowish white—it is 
very agile, and lives in pairs—its Malay name, Wouwou, is 
taken from its cry. 
S. leucisca, Schreber, pl. 3, B, (The Cinereous Gibbon) 
is covered with a soft and ash-coloured wool. The visage is 
(1) This is the Quojas morou or the Sutyr of Angola of Tulpius, who gives a bad 
figure of it, (Obs. Med., p. 271) and the Pygmy, much better represented by 
Tyson, (Anat. of a Pygmy, pl. 1,) copied by Schreber, pl. 1, B. Scotin had given 
a tolerable drawing of it, copied Amen, Acad. VI, pl. 1, fig. 3, and Schreber, 1, C. 
An individual that lived with Buffon, and which is still preserved in the Museum, 
is represented, though badly, in the Hist. Nat. XIV, 1, where he is called Jocko. 
The same specimen is much better in Lecat (Traite du Mouv. Muscl. pl. 1, fig. 1), 
under the name Quimpese. Audebert gives the -° but from the stuffed speci- 
men only—he calls it Pongo. *
