is normal, except for the great length of the canines already noted, calls for 

 but little comment. The spaces between the premolars are large in correla- 

 tion with the length of the muzzle, and the first upper molar is relatively 

 small.

This comparison of dimensions will show more clearly than any description 

 the main features in which this skull differs from that of the more typical 

 " Vulpes "; and in spite of the doubt of Mivart" 3 there can be no question that 

 ferrilatus not only is a good species, but is more differentiated than any 

 other species in the region. 



The only other skull of ferrilatus known is a very young one collected by 

 Mr. Hodgson ; it is, however, too young to show any of the specific characters 

 enumerated above.

The Cricetulus referred tof as " the little white mouse " is represented in 

 the collection by two spirit-specimens, one of which has since been skinned. 

 It appears, although closely related to Cricetulus phceus, to have been hitherto 

 undescribed.
