402 On some Mammals from British New Guinea. 



darkening to blackish brown; below the midclje line is 

 well-haired and bright orange on the basal half, becoming 

 whitish and thinner-haired on the third fourth of its length, 

 and quite naked for about 35 mm. at its tip. In the typical 

 form the tail is more thinly haired terminally, and the naked 

 part below measures 55 mm. 



Skull as in true cmiescens, but smaller in all dimensions. 



Measurements o£ the type, taken by Mr. Stalker in the 

 flesh :— 



Head and body 240 mm.; tail 175 ; hind foot (s. u.) 30; 

 ear 11. 



Skull: basal length 43'3; greatest breadth 28; nasals 

 16xG'2; palate length 24 5; length of palatal foramina 4; 

 front of incisors to back of last molar 24"5 ; combined length 

 of three anterior molariform teeth 8-2. 



Ti/pe. Young adult male. Original no. 46. Killed 15th 

 January, 1904. 



The only Phalanger of this group hitherto known in British 

 New Guinea was Ps. Forbesi, Thos., from which the present 

 animal differs by all the characters given in the ' Catalogue 

 of Marsupials' as distinguishing it i'rom Ps. canescens. As 

 compared with the latter, a native of the extreme north-west 

 of New Guinea, Mr. Stalker^s specimen is surprisingly 

 similar, considering the difference in locality, but is decidedly 

 smaller (skull 43 as against 50 mm. in basal length) and the 

 naked portion of the tail is shorter. 



Owing to the faded state of tlie type of Ps. canescens in 

 the Paris Museum, which Mr. Gerrit Miller has been good 

 enough to re-examine for me, it is difficult to be sure that 

 Ps. Bernsteini is synonymous with Ps. canescens, as has been 

 supposed, but on geographical grounds their identity is 

 probable.
