Ilah. 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 liothschild. Two specimens. 



Distinguishable fiom all other species of the genus by the 

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

 Tlie skull is also peculiar in the shape of the interorbital 

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

 Arfak. 



Pogonomys forhesi vulturnus, subsp. n. 



Like true forbesi in essential characters, but the general 

 colour is more greyish, ajid approaches '' light drab " of 

 Ridgway, as compared with the " cinnamon '' of forhesi. 

 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 oi forhesi. 



Dimensicns of the ty[)e (measured on a spirit-specimen) : — 



Head and body 1.56 mm. ; tail 216; hind foot 30; 

 ear 17. 



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

 zygomatic br<adfh 21*7; nasals ]3*3; palatilar length 17; 

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



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



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

 February' 1890 l)y Dr. Lamberto Loria, and presented by the 

 Museo Civicn, Genoa. Six S|)ecitncns. 



The difference in the general colour of the Milne-Bay 

 Poyonomys was noticed on the arrival of Siguor Loria's 

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

 specimens of forhesi iiaving been stained by rust. Now, 

 liowever, the receipt of skins shows that the cinnamon culour 

 of the Sogere specimens is quite natural.
