386 Dr. N. Severtzoflf on tJie Mammals of Turkestan. 



on I was again struck with the resemblance of C. maral to 

 C. canadensis^ Avhich I saw alive in the Zoological Gardens at 

 Berlin; but from C. elaj)hus I always distinguished the present 

 species correctly. 



This led me to a comparative examination of the three 

 forms, which showed me that I had hardly made a mistake in 

 supposing C. maral to be C. canadensis. I could only 

 distinguish the two by the labels attached to them in the 

 gardens or museums ; the differences are so trifling and indi- 

 stinct ; and at the time I even thought these differences were not 

 constant. 



It now seems to me that it would be unadvisable to retain 

 the name of C. canadensis^ var. asiatica ; and I think it 

 would be more correct to name it C. maral or C. loapitij 

 which latter name is better known to American zoologists, 

 with three or even four local varieties, namely : — 



Cervus maral {C. wajpiti). 



A. Var. americana. B. Var. asiatica. 



a. canadensis. a. sihirica. 



b. californica. b. songarica. 



Var. songarica. — These are the Thian-Shan stags, which are 

 larger than the Siberian ones, and darker-coloured in Avinter, 

 being brownish grey and not of a whitish colour; and, finally, 

 the stems and branches of the horns of Thian-Shan specimens 

 are longer and thicker. 



The marking of the skin and the division of the points 

 from the stem of the horns — in short, all the differences sepa- 

 rating G. maral from C. elaphus are present in Siberian and 

 the Thian-Shan specimens. 



78. Cervus cajpreolus pygargus. 



Is common all over the north-eastern portion, but occasion- 

 ally occurs also in the neighbouring provinces ; it is com- 

 monly to be met Avith in the mountains at an altitude of from 

 6000 to 10,000 feet above the level of the sea, hardly ever 

 descending lower than 6000. 



79. Cervus sp. ? 



This deer, which I could not exactly identify, was observed 

 in the spring of 1858, by some hunters who accompanied me 

 as far as the left shore of the Sir-Darja, near Port Peroff, in
