I have already referred to N. boettgeri (v. sup. footnote to 

 key, p. 738). Of N. h. satunini the Museum possesses a cotype 

 presented by the Branicki Museum, Warsaw. 



The fur is rather coarser and shorter (155 mm. on back) than 

 in the last species, but equally full and close. 



The colour is darker and duller, approaching " clay-colour." The 

 hands, feet, and tail pale. 



The dimensions are : — 



Head and body 153 mm. ; tail 102 ; hind foot 30. 



Skull : basilar length 34 ; zygomatic breadth 25 : alveolar iength 

 of upper molar series 8. 



Hab. Merv, Transcaspia. 



Besides the darker duller colour, other differences from N. hvttoni 

 are the smaller teeth and rather broader braincase. 



II. — Gunomys. 



1907. Gunomys, Thomas, Anna. & Mag. Nat. Hist. xx. p. 203. 



Type species, Arvicola bengalensis, Gray and Hardwicke ( = Nesokia 

 bengalensis auctorum). 



Considering how widespread the genus is throughout India, it is 

 even worse represented in the National Collection than Nesokia. Col. 

 A. E. Ward has sent specimens from the Jhelum Valley, Kashmir, 

 and this Society specimens, obtained through the Bombay Govern- 

 ment, from Pithoro in Sind. The Indus River may be accepted as 

 the western boundary of the genus, and it is hemmed in on 

 the north by the Himalayas. It ranges through Burma h into the 

 Malay Peninsula, thus extending southwards practically to the 

 Equator. 



The fur, as was to be expected, varies even more in this genus than 

 in Nesokia ; the difference between the fine long silky fur of wardi 

 from Kashmir ana the coarse, short, harsh coat of varius from Pen- 

 ang is about as great as could be imagined. 



The general colour-pattern is the same as in Nesokia; indeed, G. 

 ■wardi and iV, grifithi are almost indistinguishable by mere colour, and 

 a similar close likeness is found between the Nesokia and Gunomys of 

 Lower Sind. 



The tail is, on the average, f the length of the head and body. 



The following is a key to the species of Gunomys so far as I have
