new small Mammals from Neio Guinea. 535 



Skull slenderly built, of more normal murine proportions 

 than in many o£ the species, the muzzle not shortened and 

 the zygomata not abruptly thrown outwards. Nasals long 

 and narrow. Supraorbital edges more parallel than usual, 

 not strongly divergent posteriorly, the edges themselves 

 square but not ridged. Palatal foramina short, as usual. 



Dimensions of the type (measured on the remade skin) : — 



Head and body 112 mm. ; tail 160; hind foot 21. 



Skull : greatest length 30*3 ; condylo-incisive length 28*3 ; 

 zygomatic breadth 16*2 ; nasals 11 x 2'9 ; interorbital 

 breadth 4 ; breadth 2 ; brain-case 14*6 ; palatilar length 13 7 ; 

 palatal foramina 4*2 ; upper molar series 5. 



Hob. Eawlinson Mts., N.E. New Guinea. Alt. 1500 m. 



Type. Adult male. B.M. no. 11.10.13.6. Collected 

 June 1911 by Prof. F. Forster. Presented to the National 

 Museum by Lord Rothschild. Two specimens. 



Distinguishable from all other species of the genus by the 

 grey-based belly-hairs, these being usually white to the base. 

 The skull is also peculiar in the shape of the interorbital 

 region, which is alone similar to that in P. macrourus of 

 Arfak. 



Pogonomys forbesi vulturnus, subsp. n. 



Like true forbesi in essential characters, but the general 

 colour is more greyish, and approaches "light drab" of 

 Ridgway, as compared with the " cinnamon " of forbesi. 

 Whitish patches in front of and at posterior base of ears at a 

 maximum, contrasting with the general grey colour. 



Skull apparently quite like that of forbesi. 



Dimensions of the type (measured on a spirit-specimen) : — 



Head and body 136 mm. ; tail 216; hind foot 30; 

 ear 17. 



Skull : greatest length 36'3 ; condylo-incisive length 35*8 ; 

 zygomatic breadth 21 - 7 ; nasals 13*3; palatilar length 17; 

 palatine foramina 5*1 ; upper molar series 5*8. 



Hab. Bara-Bara, Milne Bay, extreme South-east Papua. 



Type. Adult female. B.M. no. 97. 8. 7. 64. Collected 

 February 1890 by Dr. Lamberto Loria, and presented by the 

 Museo Civico, Genoa. Six specimens. 



The difference in the general colour of the Milne-Bay 

 Pogonomys was noticed on the arrival of Signor Loria's 

 specimens, but was then supposed to be due to the original 

 specimens of forbesi having been stained by rust. Now, 

 however, the receipt of skins shows that the cinnamon colour 

 of the Sogere specimens is quite natural.
