173. NESOKIA GRIFFITHII, Horsfield. 

 HAB. Afghanistan, Pushut, Griffith. 



A. Griffith's Collection from Afghanistan. 



Fur, very soft and silky. Colour, above, dusky chestnut-brown, with 

 streaks of a plumbeous tint, the separate hairs being of a leaden colour 

 at the base, and chestnut-brown towards the extremity ; chin, chest, 

 and under parts of a lighter tint, passing into a grayish leaden colour 

 on the abdomen. Ears moderately large : thumb of the fore feet very 

 minute. Cutting-teeth flat anteriorly, comparatively large, broad, and 

 nearly white. Tail nearly naked, and shorter than the body. Length, 

 from snout to root of the tail, 6^ inches ; of the tail, 3 inches. 



In the definition of this genus (Ann. Nat. Hist. X. 265), Mr. Gray 

 states that it is " easily known from Mus by the large size of the 

 cutting-teeth, and the shortness of the tail; it appears to be inter- 

 mediate between Mus and Rhizomys." 



In the Nesokia Grijfithii this character is particularly developed, and 

 forms one of the points which distinguish it from Nesokia Kok and 

 Nesokia Hardwickii, described by Mr. Gray in the Mag. Nat. Hist. 

 N. Ser. I. p. 577, &c.
