Synonymy. 



Literature. 



Cabanis's Sand-Plover belongs to the subgeneric group JEgialophili minores, and 

 appears to be perfectly distinct from any of its allies, having black legs and white lores. 



It is only known from the mountain plateaux in the extreme north of Chili. It is 

 quite distinct from C. nivosus, which is a smaller bird, with paler feet and a white nuchal 

 collar. It appears to be nearest related to C. ruficapillus, though it is probably a temperate 

 form of its tropical ally C. collaris. It is a larger bird than any of its tropical allies, the 

 wing from carpal joint measuring about 4f inches. It is no doubt subject to some 

 variation in size, but it is only known from the type in the Berlin Museum, which 

 Herr Reichenow informs me came from Chili, and from the small series obtained from 

 Tarapaca by Mr. H. B. James (Sclater, Proc. Zool. Soc. 1886, p. 403). 



Males scarcely differ from females, but young in first plumage and adults in winter 

 plumage are unknown.
