PIJKLIMINARY DESCRIPTIONS OF THREE NEW BIRDS 

 FROM ST. VINCENT, WEST INDIES. 



BY AUSTIN H. CL.\RK. 



On working up a eullectioii of l»inls ol^taint-d l>y myself on 

 the island of St. Vincent during 1903-04, I find three forms 

 apparently well worthy of recognition. All three of these birds 

 appear to he rare in collections, which possibly accounts for their 

 not liaving l)een previously characterized. Two (Urubitinga 

 (iiitlirar'nia cancrivora nob. and Holoqidscalvs dispar nob.) are 

 only known from St. Vincent, although the former possil)ly 

 occurs on St. Lucia and Dominica ; Buteo antillarum nob. has 

 an extensive West Indian range, and may be found to be separ- 

 able into several local races. 



Holoquiscalus dispar sp. nov. 



"BARBADOS" BLACKBIRD. BEQUIA SWEET. 



'Ii/pe. From Kingstown, St. Vincent, Oct. 31, 1903. No. 12,802, female 

 adult, coll. E. A. and O. Bangs. 



Characters. Bill much as in //. inflexirostris of St. Lucia; longer and 

 more compressed than in H. martinicensis of Martinique. The male is 

 similar in color to the males of both these species, but the female is very 

 different from either, being even darker than the female of H. fortirostris 

 of Barbados, though somewhat like it in color. In size the bird is a little 

 smaller than H. martinicensis.
