ON TWO NEW SPECIES OF CINCLUS. 

 BY JOHN GOULD, F.R.S., ETC. 



I have the pleasure of bringing before the notice of the meeting 

 two new species of Cinclus, for the knowledge of which science is 

 indebted to the researches of Dr. A. Leith Adams, who collected 

 them in Cashmere. The first of these, which is very nearly allied 

 to our well-known Cinclus aquaticus, I propose to characterize as 

 C. cashmeriensis ; the other, which is more nearly allied to C. Pal- 

 lasi, as C. sordidus. 



The following are descriptions of these two birds : 



ClNCLUS CASHMERIENSIS. 



Crown of the head, ear-coverts, and mantle brown, passing into 

 deeper brown on the upper part of the back and wing-coverts ; lower 

 part of the back and tail-coverts grey, with a darker central mark on 

 each feather ; tail blackish grey ; wings the same colour as the tail ; 

 throat and breast white ; upper part of the abdomen brown, passing 

 into dark greyish-brown on the flanks and vent ; under tail-coverts 

 uniform dark grey ; tarsi brown, lighter on the front and on the 

 upper part of the toes. 



Total length 7 inches ; bill f ; wing 3J ; tail 2-J ; tarsi 1 J. 



Hob. Cashmere. 



Remark. As compared with adult males of the C. aquaticus, this 

 bird differs in being considerably larger in size, and in wanting the 

 rich chestnut colouring of the upper part of the abdomen ; the wings 

 exceeding in length those of its European ally by more than half an 

 inch. 



CINCLUS SORDIDUS. 



Crown of the head, back of the neck, throat, and chest chocolate- 

 brown, the throat and breast being lighter than the back of the head; 

 back, abdomen, and tail deep brownish-black, the abdomen some- 

 what the darkest ; wings nearly the same colour as the back ; tarsi 

 brown, lighter on the front and on the upper part of the toes. 



Total length 6^ inches ; bill -J ; wing 3^ ; tail 2 ; tarsi 1. 



Hab. Cashmere. 



Remark. If it were possible to conceive a cross between C. aqua- 

 ticus, or C. cashmeriensis, and C. Pallasi, the produce would, I 

 should say, be a bird like the one under consideration. I do not, 

 however, believe that any such occurrence has taken place, but that 

 the bird characterized as C. sordidus is a good species. In size it is 

 smaller than C. aquaticus ; at least the measurements of the only 

 example I have seen induce me to believe so.
