General external appearance above strikingly like that of 

 Ps. albertisi. Indeed the resemblance is so great that at first 

 sight the two animals appear to be identical, many and essential 

 as their detailed differences are. General colour of back rather 

 lighter and more silvery, especially where it borders on each 

 side the dark dorsal line. Ears longer, closely hairy to their edges 

 outside , but entirely without the long black hairs with which 

 they are tufted in Ps. albertisi; lower part of their outer edge 

 with a yellowish spot. Undersurface of body dirty rufous or 

 fulvous grey, little defined ; without mesial white markings. 

 Hands, feet and tail not or scarcely darkening terminally ; indeed 

 the digits are lighter than the metapodials, though there are 

 some black hairs at the 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 characters 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 i^. Canine 

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

 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-
