Tail considerably shorter than the wing, slightly emar-i- natcd, the lateral pair of feathers longest.

Sexes alike in color; old and young plumages very different. Tiiis genus is peculiar to tropical America, and contains but a single species, the A. nitida, with its two climatic races, nitida of South AmerLa nnAplagiata of Middle America. The species of Rupornis, Kaup {R. may- nirostru and R. kucorrhou), have been associated with the species of the present genus, but they are very distinct. The genem (or. more properly subgenera) most nearly related to Asturina are Lcucopterinis, Kaup of' tropical America, and Kanpifalco, Bonap., of Western Africa. The former differs mainly in more or less rounded, instead of emarginated, tail, and in having the old and young similar; the latter in having the poste- rior face of the tarsus without a well-defined row of transverse Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Baird, Spencer F. , 1823-1887; Brewer, T.
