Hah. S. Few Guinea (Fly K. district) and Aru Islands. 



Type in collection. 



This species is closely allied and very similar to Ph. thorheekiana, 

 but may be easily distinguished externally by its generally less rich 

 coloration^ paler head and neck, on which the mesial dark stripe is 

 much less prominent, much bushier tail, and by its divided hallucal 

 foot-pad. In its skull it also differs markedly by the much greater 

 development of its p.*, both above and below. 



The identity of the Papuan Ph. pilicmvda with Ph. wallacei has 

 not been previously recognized, partly owing to the immaturity of 

 the type of the latter* ; but there can be no question that the two 

 only represent one species, the insular form merely differing by the 

 somewhat duller and less rufous coloration of its posterior back and 

 hind limbs.

Oeanob-bbllied Phasoolosaib. 



Size medium, form thin and slender. Fur thick, close and soft ; 

 underfur abundant, dark slaty grey. General colour dark grizzled 

 orange-brown. Head long and slender. Face and crown uniform 

 finely grizzled yellowish grey, the tips of the hairs dark yellow. Ears 

 short, not reaching the eye when laid forward, their substance thick 

 and fleshy, black ; uniformly but sparsely covered inside and out 

 with very short shining rufous hairs. Behind ears, back and sides 

 of neck dull rufous. Back with a weU-defined mesial black line 

 commencing on the occiput and running to the base of the tail ; hairs 

 of back black, with a shining orange subterminal band, the general 

 grizzled colour resulting being not unlike that of the common Water- 

 Vole. Colour of back passing quite gradually into that of belly, where, 

 as also on the chin and chest, the orange band on the hairs becomes 

 terminal, and therefore appears brighter and more rufous ; all the 

 hairs slaty grey basaUy. Fore and hind limbs to wrists and ankles 

 like body ; hands and feet black ; palms and soles each with six 

 pads, the poUical and hallucal ones distinctly divided ; claws long 

 and strong. Tail about as long as the head and body, its basal inch 

 furred like the body ; the rest comparatively short-haired through- 

 out, but the hairs on the upperside for the proximal half rather

 several details about the adult Aru-Island specimen of Ph. wallacei described 

 by Prof, ^ohlegel.
