On a new Pseudochirus and Pliascogale. 3.57

This is a remarkably distinct species, whose systematic 

 position is not at present easy to determine. Its peculiarly 

 broad low skull distinguishes it from any Oryzomys known 

 to me, "while the entire absence of supraorbital ridges separates 

 it from Melanomys, to which its short tail and the general 

 shape of its skull j)erhap3 indicate some affinity. Many 

 Oryzomys^ however, have no supraorbital ridges, and I there- 

 fore provisionally place it in that genus.

A FURTHER small consignment of Mammals has been received 

 from the Pratt Brothers, who have been collecting in the 

 Weyland Mountains, N.W. New Guinea (approximately 

 135° 40' E., 3° 40' S.), a region hitherto almost untouched. 



The collection includes examples representing the two 

 following new mammals: — 



PseudocJiirus ca7'oli, sp. n. 



A large member of the canescens-forhesl group ; most nearly 

 allied to Ps, larvatus ; a white tip to the tail. 



Size larger than in any of the species allied to canescens, 

 more as in some of the members of the albertisi group. 

 General colour above more " buffy-biown " or rather darker ; 

 an indistinct darker median dorsal line from withers to rump. 

 Underside white, the hairs creamy white to their bases. 

 Face greyish brown, not rufous, witliout defined median dark 

 line ; chin blackish. Back of ears and a patch in front of 

 them black ; a prominent white patch below and behind them. 

 Fore limbs with the whole of their outer as well as their 

 lower side white, in continuation with the white of the belly, 

 the white extending onto the outer halves of the metacarpals ; 

 warm brown of body-colour extending in a rather luurow 

 line down the front of the forearm to the wrist ; proximal 

 part of digits blackish, lightening terminally. Beiiind the 

 outer sides of the legs and the whole of the feet are white. 

 Tail well furred proximally, brown for its basal three inches, 

 then daikening nearly to black for its next ihree inches, and
