ON SOME NEW PHALANGERS 143 



some black hairs at tlie bases of the claws. Terminal half of tail 

 naked and very coarsely shagreened along its under surface. 

 Centre of chest with a skin gland. 



Skull with the zygomata much less strongly and abruptly 

 thrown out in the orbital region than in Ps, albertisi. Nasals 

 longer and less strikingly broadened behind. Interorbital region 

 also less broadened in front, its edges raised into ridges similar 

 in character to those of the allied species, but viewed in profile 

 they are less high opposite the centre of the orbits. Bullae 

 conspicuously smaller than in Ps. albertisi, scarcely inflated at all. 



Teeth. Anterior upper incisors very long ; i^ rather shorter 

 horizontally than in albertisi, but still longer than /^. Canine 

 longer than any of the four teeth nearest to it, twice the heiglit 

 and four times the bulk of the small anterior premolar next 

 succeeding it ; — in albertisi the canine and first premolar are 

 of about the same size. Molars rather larger than in the allied 

 species. 



Below , the anterior incisors are quite different to those of 

 albertisi, being long and straight, without the peculiar concavity 

 of the upper edge characteristic of that species. A single inter- 

 mediate unicuspid tooth present on each side. Other teeth as 

 usual. 



Dimensions of an adult male, in skin : 



Head and body (c) 310 ; tail (c) 320 ; skull, basal length 63.5; 

 greatest breadth 41 ; nasals 23 X H-o; interorbital constriction 

 7; palate breadth outside m- 20. Vertical height of i^ 0.3; 

 horizontal length of ^^ 2.7; height of canine 3.4; combined 

 lengths of ms^-^ 13. Length of i^ 11, of ms^-^ 17.5. 



Hab. Mountains of Vanapa, British New Guinea. 



Co-types, two males, precisely similar to each other, in the 

 Genoa and British Museums. Collected and presented by Dr. 

 L. Loria. 



In spite of its superficial resemblance to Ps. albertisi, this 

 species may be readily recognized by the absence of the mar- 

 ginal bristles to the ears, by its uniform dull fulvous belly, b} 

 its narrower nasals, smaller bullae, the length and straightness
