Ifah. Georgetown, Pinang, Malay Peninsula. 



T//pe. Adult male. B.M. no. 98. 8. 3. 3. Collected 8th 

 April, 1898, and presented by Capt. S. S. Flower.

 Pinang having been received with the Indian Museum

G. vari'us is distinguishable from G. bengaJensis by its 

 coarse fur, variegated colour, and comparatively large size. 



Gunomys vai'i/lus, sp. n. 



Like G. varius, but very much smaller. 



Size very small, scarcely equalling the smallest S, Indian 

 species of the genus. Fur coarse ; longer piles almost con- 

 fined to the posterior back. General colour above about as 

 in G. varius, or rather more bufFy, but the mixture is finer, 

 not so coarsely variegated. Under surface dull greyish, the 

 liairs slaty at base, dull creamy terminally. Hands and feet 

 brown. Tail more tinely scaled than in G. varins, uniformly 

 brown. 



Skull very much smaller in all dimensions than that of 

 G. varius, but essentially similar in form. Nasals short and 

 narrow. Supraorbital ridges less heavily developed. Anterior 

 zygomatic plate well projected forwards, much more so than 

 in the equally small S. Indian G. hok. Palatal foramina of 

 equal breadth for their anterior two-thirds, narrowed in their 

 posterior third. 



Dimensions of the type (measured in skin) : — 



Head and body 184 mm. ; tail 137 ; hind foot 36'5; ear 16. 



Skull: condylo-basal length 40'5 ; basilar length 35; 

 greatest breadth 2i ; nasals 13 x 4-3 ; interorbital breadth 

 5-7; frontal height 12-5; palatilar length 21 ; diastema 13; 

 palatal foramina 8x2"4; length of upper molar series 

 (crowns) 7, (alveoli) 8.
