Indios). 



Seven specimens: Los Indios and Caleta Grande. 



Many years ago Poey recorded this species from the Isle of Pines 

 on the authority of Gundlach, which author later speaks of having 

 found a nest there, built in a " jucaro " tree, and constructed of twigs 

 like those of other hawks. " The egg was dirty white with a greenish 

 tinge. At the larger end were some very pale lilac spots. The di- 

 mensions were 58 by 45 millimeters." (Translation.) Mr. Zappey 

 failed to meet with the species in the island, however, and in the 

 absence of specimens Mr. Bangs was perforce obliged to follow 

 Gundlach and other authors in considering it the same as the conti- 

 nental species, U. anthracina. Shortly thereafter, however, the 

 receipt of a fine pair of adults from the coast of Cuba afforded 

 the much desired opportunity for comparison, which showed that 

 the Cuban and continental forms were quite distinct. The present 

 series, which includes two adult birds, abundantly confirms this 

 conclusion, although I cannot agree with I\Ir. Bangs that U. gundlachii 

 is only distantly related to U. anthracina. In form, proportions, and 

 style of coloration the two species are practically alike, but they may 

 be separated at a glance by their different colors. U. gundlachii is 

 chocolate-brown, with a slight purplish gloss, where U. anthracina 

 is black, except the tail, which is about the same color in both. The 

 bases of the remiges are broadly white underneath in U. gundlachii, 

 but merely mottled with white in U. anthracina. With a fairly 

 representative series of the latter before me, I fail to appreciate any 

 constant differences in the position and extent of the white bands on 

 the tail, to which Mr. Bangs calls attention. In fact, this is a variable 

 character in U. anthracina at least, and little importance can be 

 attached to it. The feathers of the upper parts are decidedly paler 

 basally in U. gundlachii than in U. anthracina, and the outer webs of 

 the primaries lighter gray. Immature birds, too, are duller in color 

 than those of U. anthracina, and the barring on the tibiae and tail 

 is not so coarse. The iris is given as dark brown in the adults and 

 light brown in the young. 



Mr. Link met with this species only in the southwestern part of the
