Primary formula—4-3-5-2-6-7-8-9-10-1. | Lores whitish 
with black bristles, the latter extending in a thin line on 
malar apex and under chin (mental apex); rectrices nar- 
rowly tipped with wood brown, in all specimens. About 
fifty per centum of the adult and second year birds examined 
personally, had yellow or straw-colored irides; but collectors 
of greater experience state that brown is the usual color in 
North ‘America. In Cuba, Gundlach gives it as ochraceous 
with an inclination to dark gray; Riley notes the color on 
three eastern Cuban specimens is given as straw yiellow 
with a brownish wash, while in two apparently fully adult 
birds shot by Palmer and himself in western Cuba, the irides 
were brown; and of two skins in my own collection taken in 
Santiago de Cuba, the adult is labeled “iris yellowish, brown- 
ish near pupil,’ juvenile “e@ray brown.’ The Porto Rico 
specimens show ochraceous-yellow, with a gray wash—Gund- 
lach. United States of Columbia—male and female, brown- 
ish yellow—Sclater. Northeastern Peru, female, light chest- 
nut brown—Taczanowski. Ecuador, light hazel brown, Ber- 
lepsch and Taczanowski; female, whitish, brownish in lower 
part—Taczanowski and Berlepsch. dirty white—Sclater. 
Rarely, both ovaries are developed in females, and as 
Bishop suggests, may account for some unusually large 
“males.” The peculiar malformation of a supernumery toe 
has been noted once by Coale, and twice by Beebe. 
Buteo platypterus antillarwm “differs from the Cuban se- 
Ties 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.’—Riley. 
According to Clark the irides of the St. Vincent bird are 
yellowish-white in all stages, and it is given by Lister as 
vellow. ‘
