164 SOCIAL PLOVER. 



The female resembles the male, but the tints are less pure, "and 

 more diiFused, particularly the under parts. 



The young of the year, according to Degland, have the top of 

 the head grey brown, bordered with russet; wing coverts and wings 

 olive brown, with lighter brown borders; forehead and superciliary 

 streak very bright buff; throat white; sides of the head, neck, and 

 crop, spotted like the wing coverts; abdomen pure white, the rest as 

 in adults. This description fairly corresponds with specimens of the 

 young in the collection of Mr. Harting. 



My figure is taken from a specimen from the Volga, sent me by 

 Canon Tristram. The egg is in my own collection; it was taken in 

 South Russia, and sent to me by Herr Moeschler. I have also a 

 series taken by Herr Glitsch in South Russia. 



The species has been figured by Bonaparte, Faun. Ital., pi. 41; 

 and Gould, Birds of Europe, pi. 292. 



Mr. Harting informs me that Gray and Hardwick^s plate, in their 

 '^''Illustrations of Indian Ornithology," of the "Black-sided Sandpiper" 

 of Latham, which they identify with Chm^adrius ventralis of Wagier, 

 is referable to the present species, and that Charadrius ventralis of 

 "Wagier is the Indian Spur-winged Plover. The latter, however, is 

 figured on another plate in the same work, and there correctly 

 designated. By some confusion the authors have figured two very 

 difierent species under the same name.
