7. Rhinolophus euryale ? 



Is distributed over the whole western half of Turkestan, 

 where it remains all the year round, at an altitude of from 1000 

 to 4000 feet — that is, on the grassy plains and steppes. 



8. Sorex pulchellus. 



Has been found about the Syr-Darja, in the north-western 

 portion of Turkestan, where it is very rare, and appears to 

 inhabit localities not more than 1000 feet above the level of 

 the sea. 



9. Sorex leiicodon. 



This shrew, as well as the foregoing species, inhabits the 

 north-western portion of Turkestan, viz. the Syr-Darja, Aris, 

 Callesse, and the neighbourhood of the Aral Sea. It may be 

 seen in the hills all the year round up to an elevation of 

 4000 feet. 



10. Erinaceus auritus. 



Is common throughout Turkestan, its vertical range being 

 limited to about 4000 feet above the sea. 



11. Ursus leuconyXj n. sp. (Z7. tsabeUimis?, Horsfield). 



The Himalayan pale-coloured yellowish-brown bear ( U. isa- 

 hellinus) described by Mr. Horsfield is known to me from Mid- 

 dendorff's account (Sibirische Reise, iii. pp. 51,53), who takes 

 it for a light southern variety of U. arctos. I cannot state 

 with certainty whether his Himalayan bear is identical 

 with the Thian-Shan specimens procured by me, which are 

 also light-coloured ; but the colour of the latter is rather 

 variable, and is certainly not constantly isabelline. Conse- 

 quently I have established my species on an important and 

 constant character, the white colour of the claws. In structure 

 it resembles U. arctos, especially in the skull, in the convex 

 forehead, and the width of the jaws ; the head just before the 

 eyes suddenly narrows, and the muzzle is extremely slender 

 compared with the massiveness and width of the temporal 

 region. The snout is shorter than in the other species ; but 

 taking into consideration Middendorff' s statement about the 

 great variation of the proportions of the skull of U. arctos, 

 we cannot fix the cranial characters of U. leuconyx, of which 

 I obtained only two complete specimens. The eyes, like those 

 of our bear, are small ; the ears are rather larger, of about the 

 same size as the muffle of the animal.
