REVIEW OF AMERICAN BIRDS. 



[part I. 



Vireosylvia barbatula. (Cuba.) 



Vireosylvia ahiloqna, Cassin, Pr. A. N. Sc. 1851, 152.— Ib. Illust. 1S54, 

 8, and 221, pi. 37 (Florida).— Bryakt, Pr. Bust. Soc. V, 1859, 113 

 (Bahamas). — Laavkence, Aun. N. Y. Ljc. 18G0 (Cuba). 



Ilah. Cuba; the BaLamas, and Charlotte Harbor, Florida. (W. Coast.) 



(No. 259,58, % , Cuba.) Proportion of quills as in V. cali'Jris, 2. =3. 4. 1. 5., 

 but the tipd of the quills closer together, and the 1st quill about half or a little 



less than half the distance 

 between 5 th and 4th ; the 

 quills narrower. 



Colors similar to those 

 of V. calidris, but of a 

 purer and paler olive 

 above ; the back tinged 

 with ash ; the cap purer 

 ash, and better defined, 

 without olivaceous wash, 

 its dusky edge more dis- 

 tinct. The superciliary 

 stripe whitish, or grayish, with the cheeks paler, and both, as well as the chin, 

 without the buff tinge. Under parts nearly pure white, very faintly tinged 

 across the breast with ashy ; the sides olivaceous ; the crissum and axillars 

 pale sulphur yellow. 



(No. 25,958, %.) Total length, 5.50; wing, 3.15; tail, 2.50; difference of 

 1st and 2d quills, .18, of 5th and 2d, .22 ; length of bill from forehead, .82, 

 from nostril, .46, along gape, .89 ; tarsus, .72 ; middle toe and claw, .60, claw 

 alone, .21 ; hind toe and claw, .50, claw alone, .23. 



The black-whiskered Vireos of Cuba, Bahamas, and Florida are 

 distinguished by the characters just mentioned from the Jamaican 

 species, and agree in coloration very well am jng themselves. While 

 in V. calidris the first quill is, with scarcely an exception, about 

 midway between the fourth and fifth, the second a little longer than 

 the third, the tendency in the present series is to have the third quill 

 rather the longer, and the first only equalling the fifth. Only in 

 No. 17,111 and 25,958, from Cuba, and 34,513, from Nassau, is the 

 first quill longer, or reaching nearly half way fi'om the 5th to the 4th.
