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 me 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
