SECOND Y ARK AND MISSION. 



sharp angles on each side ; the third also has three on each side, but those on the outer side 

 are weaker. 



In colouration this species resembles A. russatus, Radde, 1 but that is smaller, with a 

 proportionally longer tail, which is rusty red above, pale ochraceous below, and the teeth are 

 very different, resembling those of A. mandarinus. 2 A. leucura, Severtzoff, from Western 

 Turkestan, is very differently coloured ; it is described as being ashy ; the name must, as 

 already observed, be changed, as it is preoccupied. 



I find no details as to Arvicola stoliczkanus in Stoliczka's notes. He merely mentions 

 finding a new Phaiomys, — evidently this species, — at Aktagh. The specimen from the Nubra 

 valley was collected by Dr. Bellew.

Although the specimens brought differ in some respects from those from Persia, 3 siill 

 1 think the differences are not much greater than those of Persian specimens between them- 

 selves. The Yarkand and Pamir skins of this hamster have smaller ears than those collected in 

 Persia, and rather longer fur. But the most important distinction is, that in the former the 

 molar teeth are larger ; at the same time the form of the teeth is the same. 



The following dimensions are taken from the label of the specimen from Panjah (1). Por 

 comparison I give the dimensions in inches of a Persian male, (2) taken on the body like those 

 of the Wakhan animal, and (3) Pallas's original measurements 4 of a specimen probably from 

 near Astrakhan : —

The length of the ears in the Panjah specimen is intermediate between the Persian 

 and Russian measurements. Prom the label of this specimen I take the following 

 additional details : — snout to eye 048, snout to ear 09, width of fore-foot 0*2, of hind-foot 

 the same, length of hah' on the back 037, of the longer hairs tipped black 07, width of 

 head at base of ears 055. Ears rounded, soles of feet white, snout flesh-coloured, iris brown. 



The colour varies from pure ashy grey to grey with an isabelline tinge, but the same takes 

 place in Persian specimens. 



Since the above was written, both this and the next ' species have been discovered in 

 Gil git by Captain Biddulph.
