Authors have, I think, been mistaken in referring the Picolaptes 
rufinucha, of Lafresnaye, from eastern Mexico, to the P. capistratus, 
of Lesson, from, and apparently confined to the west coast of Central 
America. The specimens before mé are not in very good condition, 
but they indicate, both in coloration and proportion, differences which 
are not readily reconciled. In both species the whole top of the 
head, with the line back and in front of the eye, are blackish. In 
rufinucha, however, the exposed feathers of the back and scapulars 
are streaked conspicuously with soiled whitish, with the blackish 
external suffusion, the black sometimes forming large rounded spots 
on each side the shaft. The spots on the wings are whitish, rather 
than brownish-yellow. The tail feathers are black, broadly ended 
with white, soiled at the end, but the outer webs of all (except the 
two central), exhibit a series of six or seven quadrate white spots, 
instead of being fewer in number and confined to the outer feather. 
The under parts are soiled whitish; each feather, as far as can be 
ascertained, except perhaps the chin and throat, with two or three 
very small spots, usually in pairs, The crissum shows conspicuously
