This species is of* the same type as C. unicarinatum, Lamarck, but 

 is quite distinct, being more depressed, and having a much larger 

 umbilicus and more expanded keel.

An examination of the specimens of American Stilts in the col- 

 lection of Salvin and Godman has convinced us that two species 

 have hitherto been confounded under the name Himantopus nigri- 

 collis. 



The northern bird, which must retain Vieillot's name, extends 

 from the United States southwards as far as Brazil. Its southern 

 representative, found in South Brazil, the Argentine Republic, and 

 Chili, is easily known by having the whole top of the head white, 

 and a broad white band across the upper back just below the neck. 

 It must bear the name brasiliensis of Brehm, who has shortly 

 described this species in his ' Vtigel Deutschlands,' the previously 

 given term melanurus of Vieillot, based on Azara, if really intended 

 for this bird, involving an error in fact. 



The synonymy of the two species will stand as follows : —
