FOKBES'S PHAiAlf9ER. 



Size rather smaller than in Ps. canesoens, general proportions as 

 in that species. Sexes differing markedly in size *. Fur short, close 

 and velvety. General colour duU silvery grey. Muzzle blackish 

 brown; crown and cheeks pale rufous, without any trace of a 

 central darker line. Ears (so far as can be judged from a dried skin) 

 small and rounded as in Ps. canescens, their backs hairy, dull rufous, 

 a prominent blackish patch in front of and above them, and another 

 below and behind them, while between the two black marks, round 

 their posterior bases, the fur is pale yellowish white, connected 

 below with the pale colour of the throat. The whole region of the 

 ears markedly tufted with long fine hairs. Back grey, the rufous 

 of the crown of the head gradually disappearing on the fore- 

 quarters ; an indistinct dark band running down the centre of the 

 posterior back, not continued forwards on the head. Chin brown, 

 chest and belly dirty white, the bases of the hairs slate ; hairs on 

 the scrotum wholly pale rufous. Outsides of hmbs like body, the 

 anterior more rufous than the posterior. Hands and feet nearly 

 white, except that the backs of the metacarpals are brown. Tail, 

 both in colour and distribution of hair, similar to that of Ps. canescens, 

 except that the underside of the basal third is scarcely less hairy 

 than the upper, and the hairs themselves are everywhere rather 

 shorter. Surface of naked portion below tip rather rougher than 

 in that species. 



Skull (PL XX. figs. 1-3) smaU and lightly buUt. Nasals pro- 

 jecting rather more than 3 mUUm. beyond their junction with the 

 ascending processes of the premaxiUae, the nasal notch therefore 

 deeper than in the allied species ; posterior part of nasals but little 

 expanded, flattened, not vaulted above. Interorbital region very 

 markedly concave along its centre, its edges sharply ridged, the 

 outline of these ridges forming a sharp angle with that of the nasals 

 when viewed laterally. Rudimentary postorbital processes present, 

 and the corresponding projections on the malar bones unusually 

 well developed. Anterior palatine foramina extending to past the 

 level of the canines. Posterior palate with numerous minute 

 vacuities. Bullae small, scarcely swollen at aU. 



TeetTi remarkably reduced, both in size and number. Upper i,' 

 thick, about three times the height of i.^ ; i.° very smaU ; i.' entirely 

 absent. Canine minute, situated a very considerable distance 

 behind the incisors. P.' absent ; p.' small, oval in outline ; p.* about 



* Judging from one specimen only of each.
