272 Riley, The Broad-icinged Hawks of the West Indies. [f^^. 



The bird named Buteo antiUarum by jNIr. A. H. Clark differs 

 from the Cuban series principally in size, being smaller; in having 

 the throat generally darker and the barring on the thighs averaging 

 narrower; there are apparently no other differences. 



Mr. Clark^ gives the color of the irides of the St. Vincent bird as 

 "yellowish white in all stages," and describes^ the eggs as "dull 

 bluish white in color and .... unspotted," but jNIr. J. G. Wells^ says 

 they are "buff' color, spotted and blotched with reddish brown." 

 This latter condition may be unusual, however. 



The U. S. National Museum has an immature bird from Grenada, 

 marked male, but probably a female, and an immature female from 

 Tobago, which, though large for this form, probably belong to it, 

 or are migrants from further north — an improbable supposition, 

 as this hawk is not known to be a migrant in the West Indies, to 

 my knowledge. Although I have only examined specimens of this 

 form from two other islands of the Lesser Antilles, besides the above, 

 I think I am safe in assigning the records from the following islands 

 to it: ?Martinique, Santa Lucia, St. Vincent, Bequia, Mustique, 

 Cannouan, Carriacou, Grenada, ?Tobago.

The series from Dominica are darker than specimens from St. 

 Vincent, more sooty above, more heavily marked below, and with 

 the'bars darker, as has already been pointed out by Mr. A. H. Clark,^
