We have in the British Museum only a single specimen of this 

 species with its skull, which was obtained from the Zoological Society, 

 and is the specimen described by Mr. Waterhouse in his Natural 

 History of the Mammalia, i. p. 268. The other specimen there 

 indicated as being in the British Museum is a young C. maculatus. 



In Lesson's figure in Cent. Zool. t. 10, it is represented as uniform 

 blackish-brown, with rather large white-edged ears ! 



The larger size of the teeth and the flatness of the forehead at 

 once separate this from C. maculatus. 



4. CUSCUS ORIENTALIS. 



Ears produced beyond the fur, naked internally ; forehead con- 

 cave. Male white. Female pale reddish-brown, with a darker 

 longitudinal streak ; skull with a narrow concave forehead ; grinders 

 moderate.
