Eange. — Tobago, Trinidad, Venezuela, Guiana, and northern Brazil ; 

 accidental in eastern Massachusetts (?) 



Sp. char. — Adult (No. 88468, U. S. National Museum, Surinam; 

 Count von Berlepsch) : Above dark bronze-green, including two mid- 

 dle tail-feathers, the latter, however, much duller green than the back ; 

 remiges dusky, very faintly glossed with purplish ; outer tail-feather 

 dusky, inclining to blue-black subterminally, the tip dusky gray for 

 about .20 of an inch ; next feather similar, but with the dusky grayish 

 tip much less distinct, and the outer web slightly glossed with dull 

 bronze-greenish, except for terminal third ; next feather with dusky 

 gray tip reduced to a narrow terminal margin, and the outer web dis- 

 distinctly dusky bronze-greenish, except terminally ; fourth feather 

 similar, but no trace of grayish at tip. Malar region, chin, throat, and 

 chest, bright metallic emerald-green, more yellowish green laterally, 

 the feathers of the chin and throat dusky grayish at base, with a white 

 bar between the dusky and the green, those of the chest dusky imme- 

 diately beneath the surface ; breast, sides, and flanks bronze-green ; 

 sides of belly similar, but feathers margined with pale grayish or gray- 

 ish white; middle line of belly (narrowly) white; downy femoral tufts 

 pure white ; under tail-coverts brownish gray, broadly margined with 

 white. Upper mandible black ; lower pale yellowish brown (pinkish in 

 life), becoming blackish at tip; feet dusky. Length (skin), 3.90; wing, 

 2.15; tail, 1.20 (outer feathers a little shorter); exposed culmen, 0.80. 



A specimen of this species is in the collection of Mr. William Brew- 

 ster, which is said to have been taken in the vicinity of Cambridge, 

 Massachusetts, in August, 1865. If it were really taken there, its occu- 

 rence must of course be regarded as purely accidental. (See remarks
