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 ®?°. Mr. F. M. Chapman has recently 
proposed to separate this bird from the South-American form as Colymbus dominicus 
brachyrhynchus (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 
(¢. 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 
darker below. ae 
We agree with Mr. Chapman that the birds with the longest bills are those from 
San Domingo, Cuba, and Jamaica, and Mr. Oates also remarks on the larger size 
of the eggs of Jamaican examples as compared with those from Antioquia?!. 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. domenicus of Linnzus,
