176 Catalogue of Mammalia inhabiting [No. 171. 



Hab. — Purtis (on the Malayan Peninsula.) 

 Borneo, Java (?), Sumatra (?). 

 In a young male of this, apparently everywhere difficultly procurable 

 species, the face during life was intense black, except the white-haired 

 lips and the chin, which were of a milk-white colour. In the preserved 

 specimen, the latter soon changed into the dull brownish- black of the 

 rest of the face. The interdigital membrane, often loosely connecting 

 the first phalanges of the four fingers and toes in S. obscurus, alboci- 

 nereus, cristatus and other Malayan monkeys, was also present in this 

 individual, in which even the first and second phalanges of the index 

 and middle toe were thus connected. In preserved specimens, the in- 

 terdigital web becomes shrivelled and indistinct, and therefore, being at 

 all times a very questionable, if not altogether inadmissible, specific 

 character, ought in such state to be least relied upon. On its arrival at 

 Pinang, the animal was in too sickly a state to allow of its natural habits 

 being observed.
