442 QUADRUMANA. 



Their activity and address, while alive, was astonishing : they 

 launched themselves, by means of their long arms, from branch to 

 branch, in their spacious compartment, with the greatest ease, and with 

 an air of nonchalance, as if the most apparently difficult feats were 

 merely trifles. They were extremely gentle, and rather timid ; it was 

 only occasionally that they exerted their voice, which was a loud, disso- 

 275 nant, monosyllabic cry, continued for 



some time without intermission. 



The annexed figure (2 75) represents 

 the skull of one of these individuals, 

 preserved in the cabinet of osteology 

 in the museum of the Zoological 

 Society. 



According to Mr. McClelland (see 



Proceedings Zool. Soc. p. 148, 1839), 



uii of Hooiock. the Hoolock inhabits the Cossiah moun- 



tains and valley of Assam : its colour is uniformly black, except the 

 eyebrows, which are white. Some individuals are greyish yellow. " It 

 is possessed of the most wonderful activity, making use of its arms in 

 swinging from tree to tree ; nor is the female in any way restrained in 

 her movements by the young, which she carries suspended to her body."

HYLOBATES CHOROMANDUS. (Hylobates Choromandus, OGILBY, in Proceed. Zool. Soc. Lond.

SPECIFIC CHARACTERS. Fur full and woolly ; that on the head elongated and erect; colour, 

 pale yellowish brown ; beard full ; this, with the chest, axillae, and abdomen, brown ; 

 nose elevated ; face covered with short, yellowish grey hairs. 



LOCALITY. Continental India, probably the Malay Peninsula. 



DESCRIPTION. The head is large and rounded ; the nose is prominent 

 at the end, with broad septum between the nostrils ; the toes are all free ; 

 the fur is full, deep, woolly, and glossy, that on the head forming an 

 upright, bushy wig. The general colouring resembles that of H. agilis, 

 and may be described as of a pale yellowish brown, or tawny white ; full 

 whiskers surround the face ; and these, together with the beard below the 

 chin, are of a dark chocolate brown, which colour, but of a paler tint, 

 tinges the chest, the axillae, and the abdomen ; the hairs on the fingers and 

 toes are black to the nails, but the rest of the hands and feet are of the 

 same hue as the arm and leg, &c. ; the face, which is covered with close, 

 minute hairs, particularly about the nose, is of a pale greyish brown, 

 instead of being naked and black, as in H. agilis.
