Mr. Lawrence'a type of albilinea is alinont precisely like itâa little larger, and with patches of a more bluish gloss on the back. ' ' ' '- '^ "'"â¢â ""' '"":â â This species is very similar to P. leucorrhoa,* of iJufiios Ayres, which is, however, much ldr}.rer, and lacks the concealed white of the forehead and hind neck. The greenish-black collar margining the jugulum in leucorrhoa is more nearly continuous below, and is in a measure completed by concealed dusky edges to the feathers across the breast. There is no dusky appreciable on the shafts of the feathers of the under parts, and almost none on the rump, and there is no distinct white at the base of the tail feathers. The outer tail feather is narrowly edged with whitish. An albino '^.vallow, collected by Col. Grayson, at Mazatlan, heloiigs, as nearly as I can ascertain, to H. albilinea. Both these species are distinguished from P. leucoptera of eastern, and P. meyeni of western South America, by their white loral stripo or line. I add description of these two species in order to complete the history of the genus. ' Hirundo leucorrhoa. Jlirundo leucorrhoa, Vieill. Nonv. Diet. XI«', 1817, 519, and Encycl.
