392 Mr. S. A. Buturlin on the Geographical 



synonymy. Its range is confined to the valley of Zerafshan 

 in Buchara, so that it is the most eastern representative of the 

 little group of rufous-bellied Pheasants, and is by no means 

 a near relative of /'//. mongolicus, though it has a white collar 

 just visible, or of Ph.persicus, though it somewhat resembles 

 this last in its breast-colour. 



In the north the water-parting of the Zerafshan and the 

 Syi'-Daria serves as a limit between this bird and Ph. tur- 

 cestanicus, with its black belly, greyish wings, and broad 

 collar (not to mention other points of dissimilarity), and in 

 the south the Gissar Mts. separate it from Ph. bianchii with 

 its black belly and blackish-green throat. To the west its 

 range nearly meets that of Ph. zarudnyi, as in times of high 

 floods the Zerafshan reaches the Amur-Daria. But, so far 

 as I know, these two birds are specifically distinct, as 

 Ph. zerafshanicus seems always to be recognisable at a glance 

 from the members of the group of Ph. principalis by its collar 

 and the colouring of the breast. In the Museum of my friend 

 Baron Harald Loudon I have examined specimens from the 

 most western part of its range, and they do not differ from 

 my own specimens from Siadin, and from others that I have 

 seen from still more eastern parts of the Zerafshan valley.
