O CATALOGUE OP MAMMALS FROM NEW GUINEA. 



of the Koala, is also common to the species of Cuscus, and is pro- 

 bably produced by the habit of the animal sitting on its rump, rolled 

 up into a ball, on the fork of the branches of trees. 



The skull shows that the animal is much younger than the label 

 indicates, as it appears only to have the milk teeth, and the broad 

 lower incisors of the younger specimens of this genus. The sjcull 

 differs both from that of C. ursinus and C. maculatus, but it is too 

 young to predict what may be the normal form of the adult animal. 



The front half of the space between the eyes is rather convex, but 

 not nearly so much so as the young skull of C. maculatus ; and the 

 front of the forehead just behind the convexity described is rather 

 concave ; this concavity has no resemblance to the deep concavity 

 occupying nearly the whole space between the eyes in C. ursinus and 

 C. maculatus. 



4. Cuscus URSINUS. 



Phalangista (Ceonix) ursina, Temm. Monog. i. 10. t. 1. f. 1-3 ; 

 t; 2. f. 1-5, skull; t. 3, skeleton; Lesson, Cent. Zool. t. 10; Water- 

 house, Mamm. i. 267, part. 



Cuscus ursinus, Gray, Proc. Zool. Soc. 1858. 



Ears almost hidden in the fur, clothed with fur internally and ex- 

 ternally ; fur blackish-ash, with larger silvery hairs ; head, throat, 

 belly and tail rather pale brown ; forehead flat, concave ; forehead 

 of the skull flat, deeply concave ; grinders large, in a strongly-arched 

 series. 



Hab. Celebes. 



a. The specimen with its skull, which was obtained from the Zoolo- 

 gical Society, and is the specimen described by Mr. Waterhouse in 

 Mammalia, i. p. 268. 



The other specimen there indicated as being in the British Mu- 

 seum is a young example of 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 aud the flatness of the forehead of the 

 skull at once separate this from C. maculatus. 



5. Cuscus Celebensis. 



Ears produced beyond the fur, naked internally. Male and female 

 alike, ashy-grey, grizzled with silvery hairs ; the nape and the upper 

 part of the middle of the back blacker, but without any distinct 

 dorsal streak. 



Cuscus Celebensis, Brit. Mus. ; Gray, Proc. Zool. Soc. 1858, t. 62. 

 Hab. Celebes ; Macassar (Wallace) ; San Cristoval (Macgil- 

 livray). 



a. Young animal, from the island of Macassar. Procured from 

 Mr. J. E. Wallace in 1851.
