the True Pheasants. ^77 



the feathers, and in having a more golden, less coppery sheen 

 on the upper back. Specimens of this bird were procured by 

 Col. P.K. Kozlow, 10-12 (22-24) Jan., 1900— five males and 

 two females — in the southern part of Alashan, in the oasis of 

 Soho-Khoto near Tshen-fan, some 100 kilom. from the 

 northern slopes of the Eastern Nan-Shan. 



Dr. V. L. Bianchi first pointed out the distinguishing; 

 characters of this form, but took it for an individual variety 

 of P. strauchi. The following facts, however, prove, as it 

 seems to me, that this bird is a geographical representative of 

 P, strauchi. P. sohokhotensis is met with yiorth of Nan-Shan, 

 where not a single specimen of typical P. strauchi has been 

 procured, though Alashan has been well explored zoologically 

 by Przevalski, Kozlov, and others. On the other hand, south 

 of Nan-Shan, in the valleys of Tatung and Buhuk-gol, on 

 the Amdos Plateau, and in Southern Kan-su, where typical 

 P. strauchi abounds and was obtained by Abbe David, 

 Przevalski, Holderer, and Kozlov in very large series, no one 

 has met with P. sohokhotensis. 



Between the two areas mentioned, on the northern slopes 

 of the Northern Tatung range, intermediate specimens, 

 though much nearer to typical P. strauchi, are met with 

 (two males and one female, 10-11 Febr., 1900, Yarlyn-gol, 

 by Col. Kozlov). Therefore 1 treat Kozlov's Pheasant as 

 only a subspecies or geographical race of P. strauchi. 



Dr. Bianchi points out (1907, Aves exped. Koziowi, p. 200) 

 that one specimen from Northern Sze-chuan (Hwo-zsi-gou, 

 north from Lun-ngan-fu, 9 Jan., 1894, procured by M. i\I 

 Berezowski) is very near to Soho-Khoto specimens. 1 think 

 that this does not prove P. sohokhotensis to be only an 

 individual variety of P. strauchi, as in Sze-chuan, as well 

 as in Soho-Khoto, typical P. strauchi is evidently not met 

 with *, and Dr. Bianchi himself admits that the range of 



* Messrs Bianchi and Berezowski (Aves exped. Potanini, 1891, p. 18) 

 mention P. strauchi, one specimen, from the river Hei-ho, at Nan-pin, 

 N. Sze-chuan, July 1885. But Nan-pin is situated near the limits of 

 Xan-su, nearly 50' north of Lun-ngan-fu, and, moreover, in 1891 these 

 authors did not clearly distinguish between P. strauchi and the allied 

 forms. Thia specimen is not now in the St. Petersburg Museum.
