Show 139 GENUS HETEROSPIZ1AS, SHARPE. Urubitinga AUCT. ( nee LAFRESXAYE). Spizigeranus GRAY, Hand List, i, 1869, 9 ( nee KAUP, 1644). Heterospmas SHARPE, Cat. Ace. B. M. 1874, 160. Type Falco meridionalis GM. CH.- Similar to Uriibitinga, but wings larger proportionally, reaching to or beyond the end of the comparatively short tail. Tibial plumes better developed, and feathers of the pileum longer and more lanceolate. Plumage more variegated, rufous prevailing. Five outer primaries with inner webs sinuated; third, fourth, and fifth quills nearly equal and longest, the fourth usually exceeding the rest; first shorter than the seventh. Tail more than half as long as the wing, slightly, bat decidedly, emarginatf d, the lateral pair being longest.* Tarsus much more than twice as long as middle toe; outer toe nearly as long as the middle; inner much shorter; hind toe a little shorter than the inner. Claws moderate in size, of normal form, decidedly graduated, the outer being only about halt the length of the posterior, which is equal to its digit. Toes with large transverse plates in an uninterrupted series, and tarsus with continuous frontal and posterior series of similar scutellte. A well- developed web between outer and middle toes. Less than one- third the upper portion of the tarsus feathered in front. Bill rather small, exactly as in Uriibitinga anthradna. With a general correspondence to Urubitinga in most of the external features of form, this genus, or more properly subgenus, differs sufficiently in the greater development of the. remiges and tibial plumes, the more lanceolate form of the feathers of the pileum, and the strikingly different coloration.
