?. 38, 39. Kama Valley, 12,000’-13,000', 24th August. 
On laying out all the available Himalayan specimens of 
this group—some sixty in number,—from localities ranging 
from Kashmir on the west through Kumaon to Nepal, we 
have come to the conclusion that three subspecies may be 
recognized of O. roylet. Its type-form would be that. of 
Kum aon, where Strachey obtained specimens exactly matching 
Ogilby’s type from the “ Choor Mountains” (presumably 
Chaur Peak, near Simla). Anda synonym of it would be 
O. hodgsoni, Blyth, two of. whose three originally mentioned 
localities are in the range of O. roylet royler. 
Then on the west the somewhat greyer, but not materially 
different O. wardi of Kashmir and Hazara should be termed 
O. roylet wardi, while eastwards in Nepal Hodgson’s nepal- 
ensis, in turn darker than royle?, would be a third subspecies, 
found in a more saturate region, ‘The relation to these three 
of O. +. chinensis, Thos., described from still further east at 
Ta-chien-Lu, we are at present unable to be certain about, 
owing to the absence of specimens showing the seasonal 
phases. The type of that form was kijled in May, so that 
there is no evidence as to whether or no it takes on a rufous 
mantle in the later summer.

A grey Pika of the size of O. reylei, without contrasted 
rufous at any season. 
Size about as in OV. roylei, of which the subspecies nepal- 
ensis was also obtained by the Expedition. General colour 
above light grey with a slight drabby tinge, the tips of the 
hairs blackened. No conspicuous seasonal changes, the new 
suminer fur coming up of practically the same colour as the 
warm winter fur. Head and shoulders without strong 
rufous, the species contrasting in this respect with all the 
subspecies of reyle?, in which these parts turn a more or less
