fur very ragged on the 6th of June at Duba, and as this specimen agrees v ^ 
Dr. Gunther’s description of the type of L. macrotis, obtained by Captain Biddulp i 
same spot, I have no hesitation in concluding that the skin without a label is from 
It is the only skin in the whole collection which presents the appearance of having been ^0 
when just losing its long winter fur. Duba is a camping ground at an elevation of * 
feet on. the north side of the Kuenlun, on the road from Yarkand to Yangi Diwan a 
Karakoram pass vid Kugiar. pi' 
Although I felt very doutful about it, I referred this skin to L. cmritm until 1 Sct p

In the specimen collected by Dr. Stoliczka, the long hair on the back is leaden-b^ ^ 
the base and for the greater portion of its length, then dirty white, the ends being 6 
a few hairs having black tips. But the new short fur which is growing between the F ct)
