This little Grebe has a wide range in the New World, and has been recorded as 



extending over a large part of South and Central America and the Greater Antilles, and 



as occurring also in Texas and Lower California ^ 20. Mr. F. M. Chapman has recently 



proposed to separate this bird from the South-American form as Colymbus dominicus 



hrachyrhynchus (Bull. Amer. Mus. Nat. Hist. xii. Art. xix.). He would also distinguish 



the Texan bird as a separate subspecies under the name of C. dominicus brachypterus 



(t. c. p. 256), on account of its shorter bill and wings, the whiter underparts, and the 



lesser amount of fuscous colour on the sides of the body. The extent of white on the 



under surface of all Grebes seems to depend upon the age of the individual and the 



season of the year, and the greater or less amount of the fuscous colour is, in our 



opinion, due to the approach of the nesting-season, when adults become gradually 



We agree with Mr. Chapman that the birds with the longest bills are those from 

 San Domingo, Cuba, and Jamaica, and Mr. Gates also remarks on the larger size 

 of the eggs of Jamaican examples as compared with those from Antioquia2i. If, 

 therefore" this character were confined to specimens from the Greater Antilles, it might 

 be possible to separate them, and they would be the true P. dominicus of Linnaeus.
