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, Badde, 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 Phaiomy-s ,—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 still 
I 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 Panj ah (1). Eor 
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. Erom the label of this specimen I take the following 
additional details :—snout to eye 0*48, snout to ear 0*9, width of fore-foot 0 - 2, of hind-foot 
the same, length of hair on the back 0‘37, of the longer hairs tipped black 0*7, width of 
head at base of ears O'55. 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 
G-ilgit by Captain Biddulph.
