Description
"Aithurus polytmus, the Long-tailed Hummingbird, peculiar to Jamaica, the two tail-feathers next to the outer pair are immensely elongated, and, after crossing one another, bend outwards in a curve; the lateral rectrices are bluish-black, as is the head with its divided crest; all the outer parts being luminous green, and the bill red with black tip. The female is chiefly green above and white below, with brownish brown." A. H. Evans, 1900
