pty BREWSTER AND BANGS—A NEW AITHURUS 49 
1894. Aithurus taylori Rothschild, Bull. Brit. Orn. Club, Vol. III, p. 46, based 
on two males from the District of St. Andrew, just north of Kingston, 
Jamaica, each of which had a large ruby-colored spot on the throat. Mr. 
C. B. Taylor, who took the specimens, said he had frequently met with this 
ruby-throated variety in this locality. Hartert considers this “an aberration 
of the male,” and of course of the yellow-billed species. In the large series 
of A. polytmus taken by Scott in the vicinity of Kingston, there is one young 
male with two or three ruby-colored feathers in the throat. 
Gould, in his monograph, figured and described the red-billed 
species (the color of the bill being taken from accounts of the 
bird in life, and of course not from dried specimens). Elliot, in 
his Synopsis, appears to have known this form only, as did Salvin 
(in Cat. Birds Brit. Mus., Vol. XVI); and Hartert, in Das Tier- 
reich, Trochilide, 1900, makes no mention of the small black- 
billed species, which apparently was unknown to him, too, even 
at this late date. 
Aithurus scitulus' Brewster and Bangs, sp. nov. 
Type, from Priestman’s River, Portland Parish, Jamaica, ¢ adult, no. 37,405, 
coll. of Museum of Comparative Zodlogy, Cambridge, Mass., collected Feb. 11, 
1891, by W. E. D. Scott. 
General characters.— Color pattern and form as in A. folytmus (Linn.), 
except that the lengthened second rectrices are narrower; size considerably 
less; bill short, very slender, and wholly black; green color of back much 
darker and without a trace of coppery tinge; under parts, in the male, much 
darker, less yellowish green. 
Color.— Adult male: pileum and elongate occipital crest black; back, 
rump, upper tail coverts, and wing coverts, shining dark grass-green (without a 
trace of the coppery green of these parts in 4. folytmus); under parts lumi- 
nous emerald-green (much darker, less yellowish, green than in 4. polytmus) ; 
wing purplish brown, outer edge of first primary narrowly white; under tail 
coverts purple-black; tail purple-black with a slight greenish tinge on middle 
rectrices, above; bill short, slender, and wholly black. (The bill in the adult 
male of A. po/ytmus, in dried specimens, is clear yellow with a black tip.) 
Adult female: pileum dark brown with slight green tips to some of the 
feathers; back, rump, upper tail coverts, and wing coverts, dark shining 
grass-green (without a trace of the coppery green of these parts in 4. polytmus); 
under parts and under tail coverts white, with green spots on sides of neck 
and body; wing purplish brown, outer edge of first primary narrowly white; 
1 Scztulus — handsome, pretty, graceful.
