D. Length of head and body less than 160 mm. 



a. Colour brighter. (Kandahar.) (9) N. huttoni, Blyth. 



b. Colour duller. (Merv.) (10) N. satunini, Nehring. 



Note. — N. huttoni satunini was described by Nehring from the 



Merv Oasis in 1892 (I. c. inf.), but ten years earlier Baddle and 

 Walter (Zool. Jahrb. iv. p. 1036, 1889) described N. boettgeri from 

 the bank of the Amu Darya, where the Trans-Caspian Railway 

 crosses that river. The type localities of the two species were 

 therefore close together. 



I have seen no specimen of N. boettgeri, and, except that the 

 tail-length is given as 46 mm., I can find no essential differences 

 between it and N. satunini. If the tail-length recorded for the 

 Amu Darya specimen is incorrect, it is probably not different from 

 the Merv species. This seems to be the conclusion also arrived 

 at by Mr. Thomas (Ann. and Mag. Nat. Hist, xx. p. 200, 1907). 



(1) Nesohia brachyura, Biichn. 

 1889. Nesokia bracliytira, Bachner, Mamm. Przewalsk p. 82. 



Fur long (25 — 30 mm. on back) and soft ; scattered hairs od 

 flank and rump 10 mm. longer. 



Pale tips of hairs buff on the back, fading to white on the 

 belly. General colour from tawny on the back to greyish white on 

 the belly. Hands, feet, and tail pale. 



Dimensions : — 



Head and body 257 mm. : tail 116 ; hind foot 43 : ear 11"2. 



Skull : basilar length 45 ; zygomatic breadth 42 : alveolar length 

 of upper molar series 12. 



Hob. Lob Nor (lat. 40° N., long. 90° E.). 



Very closely related to the next species ; it appears to have a pro- 

 portionally shorter tail and a longer skull (especially noticeable in 

 the portion in front of the orbits). A cotype in the Natural History 

 Museum, received from the St. Petersburg Museum, gives measure- 

 ments even more close to those of N. scvllyi. 



(2) Nesokia scullyi, Wood-Mason. 



1876. Nesokia scullyi, Wood-Mason, Proc. As. Soc. Beng. p. 80. 

 The type specimen (skin and skull) is the only known representative 

 of this species. Blanford has figured it (' Second Yarkand Mission : 

 Mamm.,' p. 49, pis. viii. a, x. a), and both he and Dr. Anderson 

 a. A. S. B. p. 224, 1878) have re-described it.
