18/6.J MR. H. E. DRESSER ON A NEW TETRAOGALLVS. 675 



extends I cannot positively say ; but there is a specimen in the Cam- 

 bridge Museum sent by Mr. Blyth and stated to have been obtained 

 in " India ;" but no precise locality is given. All the other specimens 

 from India and Baluchistan are referable to L. platgrhyncha. I may 

 add that there is a specimen of L. sibirica in full summer dress, from 

 Siberia, in the Cambridge Museum. 



9. On a new Species of Tetraog alius. 

 By H. E. Dresser, F.Z.S. 



[Received June 20, 1876.] 



Mr. Charles Danford, who has just returned from the Taurus 

 mountains with a rich collection of mammals and birds, has brought 

 a fine series of specimens of a Snow-Partridge, which he has 

 requested me to compare and determine. As I find it is as vet 

 undescribed, and quite distinct from any known species, I propose to 

 give it the name suggested by him of Tetraogallus tauricus, as 

 the Taurus range appears to be its true habitat. 



Though allied to Tetraog alius caucasicus, this species is very easily 

 distinguishable from that bird, not only by its coloration, as will be 

 seen by the detailed description, but also by its much larger size. 

 The following is the description of a pair selected from the series.

 cervino cinereo ; co/lo postico et dorso antico cervino-cinereis ; 

 corpore supra reliquo sicut in Tetraogallo caucasico picturato, sed 

 pallide cervino cinereo nee saturate cinereo ; alis sicut in T. caspio, 

 sed tectricibus majoribus magis cceruleis et ad basin minus vermi- 

 culatis ; Cauda sicut in T. caucasico, sed pallidiore ; J route, stria

 rate cana ; guiture etpectore superior e cinereo-canis, plumis cinereo-
