7*. [Spermophilus bactrianus, Scully, I. c. p. 70, may be added in here as an additional 

 species.] 



8. Gerbillus erythrttrtts, Gray. 



a. Gulran, 25/2/85. b. Between the Hamun of the Helmand and Khusan. 

 [Blanford, torn. cit. p. 70. 



The obtaining of tbe above two specimens extends the area of the range of this 

 Gerbillus northwards to Bala-morghab, and gives a link between Kandahar and Shiraz. 

 —J. E. T. A.] 



8*. [Insert litis bactrianus, Bly., as an additional species (Scully, t. c. p. 72).] 



9. Cricetus phjetts, Pallas. 

 a. Bala-morghab, 23/1/85. 

 Blanford, torn. cit. p. 58. 



10. Arvicola mandarinus, Milne-Edwards (?). 

 a, b. Gulran, 13 3 and 1/4/85. 



These two Voles quite agree with the Afghan specimen doubtfully referred to A. 

 mandarvnus by Mr. Blanford in his paper on the Arvicola? of this region (J. A. S. B. 1. 

 pt. ii. p. 108, 1881). The following are their measurements, in spirit : — 



Head and body. Tail. Hind foot. Forearm and hand. Ear (above crown), 



millim. millim. millim. millim. millim. 



Eoot-pads 5-6. Mamma? 2-2=8. 



10*. [Insert Arvicola guentheri, Danf. & Alst., as an additional species (Scully, t. c. 

 p. 72).] 



11. Ellobius fttscicapillus, Blyth \. 



a, b. Gulran, 19 3 and 1/4/85. c. Bala-morghab, 15/1/85. d. Karaol-khana, 15/2,85. 



This species is by far the most interesting of the Mammals found by the Commission, 

 as it was hitherto only known from the type specimens obtained more than forty years 

 ago at Quetta, and described as Georychus fuscocapillus by Mr. Blyth %, who later § 

 formed a special genus, Myospalax, for their reception. In order to find out the true 



t Dr. Scully (t. c. p. 73), than whom there is no better authority on such a point, describes this animal as a new 

 species, under the name of E. intermedins. The cranial and dental characters he gives, however, although at first 

 sight they would naturally appear to be of specific importance, prove to be so variable within the present series 

 that I feel I must still adhere to the above determination, despite the advantage Dr. Scully has of me in being able 

 directly to compare the Afghan specimens with Blyth's original types.
