Localities. — Central Kashmir, tlie Pir Panjal range, and the Kaj Nag 

 Mountains. 



This species appears to closely resemble Arvicola ivynnei, Blanford, 

 and may, perhaps, be only a geographical race of the same. It has, 

 however, considerable longer ears and shorter tail. It also differs in 

 color, being j^ellowish-brown, rather than, "dark rich brown," or "dark 

 chestnut," which are tlie colors given by Mr. Blanford for A. wynnei. 

 The type of the latter species is from Murree (Marri), Avhich is in 

 llawul Pindee, about one hundred miles west of the Pir Panjal i>ass 

 and across the Jhelum Eiver. 



Dr. Abbott remarks that the surface of the ground in many of the 

 alpine valleys of the Pir Panjal range is completely honeycombed by 

 the burrows of this species. The elevations at which the sj)ecies were 

 obtained are indicated in the following list of specimens:

|«if?. Male. Pir Panjal range, August 30. 1891. 8,500 feet. 



59293. Male. Knj Nag Mountains, April 23, 1891. 8,000 feet. 



21690. Male. Krisbnagunga Valley, May 10, 1893. 7,000 feet. 



ARVICOLA MONTOSA, new species. 



Size of the single specimen, small. Tail vertebrii> about one-third the 

 length of the head and body together. P]ars as long as the fore foot 

 from the wrist (without the claws), but not overtopping the quite long 

 fur. Soles with six tubercles ; the hinderinost in the middle of tlie sole. 

 Behind this point the sole is hairy. 



Color above, dull grayish brown, as in A. fertilis^ but considerably 

 paler than in that species. Under surfaces white, very lightly tinged 

 with brown, and the gray of the base of the hairs plainly seen. Feet 

 white. Tail bicolored, corresponding with the coloration of the body. 

 The long hairs at the extremity are mostly from the upper side of the 

 tail and therefore dark. Ears clothed within with short yellowish- 

 brown hairs. The anterior outer margin, except at the tip, with long 

 hairs like those of the body, A tuft of long, nearly pure-white hairs 

 behind the ears. Nose dusky brown. Claws jiale, overhung with long 

 white hairs. 



Dentition that of the subgenus Alticola, and similar to that of A. 

 hiaiifordi, but with four external angles on the posterior upper molar. 

 Internal angles of the same tootli, three in number. Anterior lower
