54 ANTHEOPOID APES. 



The dark gi'f'y gilibon (Hylobates funereus, Is. 

 Geoflf. Saint-Hilaire) is of au ashen grey colour on 

 the upper and outer side of its limbs, verging into 

 brown ; and on the under side it is dark brown. 

 There is a narrow strip of light grey round the face, 

 with a darker band round the back of the head. It 

 is found in the island of Sulu.* 



In addition to these species of gibbons of which 

 we have given a brief account, there are several 

 others — as, for example, Hylobates concolor (Harlan), 

 from Borneo ; II. Muelleri (L. Martin), from the 

 same place; H. clwromandus (Ogilby), from India, 

 and many others. But since our sjjace is limited, 

 the description given above must suffice for a diag- 

 nosis of the species. 



* A very good coloured illustration of Hylobates funereus, 

 probably taken from life by Werner, may be seen in Is. Geoff. 

 Saint-Hilaire' s Description des mammiferes nouveaux, on impar- 

 faitement coniius de la collection du Museum d'histoire natwelle.
