8 CATALOGUE OF MAMMALS FROM NEW GUINKA. 



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

 bably ])rodiieed by tbe liabit of tlie animal sitting on its rum]), rolled 

 up into a ball, on tbe fork of tbe brandies of trees. 



Tbe sknll sbows tbat tbe animal is mucb younger tlian tbe label 

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

 lower incisors of tbe younger specimens of this genus. The skull 

 differs both from tbat of C. ursiiuis and C. maoiluttis, but it is too 

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



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

 not nearly so much so as tbe young skidl of C viactilatus; and the 

 front of tbe 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. ursirms and 

 C. maculatus. 



4. CUSCUS URSINXJS. 



P/ia/anc/ista (Ceonix) urshia, 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 ursmus. 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. '2G8. 



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 and 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 ; tbe 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.
