ANTHRACOTHORAX AURULENTUS (Audebert and Vieillot).

PORTO RICAN MANGO.

Similar to A. dominicus but decidedly smaller; adult male with black of under parts confined to chest and breast, and middle rectrices usually much more coppery bronze; adult female with basal portion of lateral rectrices light grayish, or partly so, instead of more than basal half wholly chestnut-rufous,[1] black of subterminal portion brightly glossed with bluish green, and under parts more extensively and uniformly grayish, the sides without green spotting or inter- mixture.

Adult male. — Above metallic greenish bronze, golden bronze, or (more rarely) coppery bronze or bronze-green, the middle rectrices dull blackish bronze to bright coppery bronze; tail (except middle rectrices) dark violet-chestnut or maroon-violet glossed with metallic violet-purple, the rectrices broadly margined terminally with glossy steel-blue; remiges dull slate-blackish or dusky faintly glossed with violet-bluish; chin and throat metallic greenish bronze to golden bronze; chest and upper breast opaque velvety black, passing into dull brownish gray on sides, flanks, and lower abdomen; under tail- coverts dusky brownish gray, usually more blackish subterminally, usually margined (more or less distinctly) with paler, and faintly glossed with violet; conspicuous femoral and lumbar tufts white; bill black; iris dark brown; feet blackish; length (skins), 105-111 (108); wing, 59-65 (62.5); tail, 32-39 (36.7); culmen, 21-25 (22.9).[2]

Adult female. — Above metallic bronze-green to golden bronze, usually much duller on forehead and crown; middle rectrices dull bronze-green to bright bronze (rarely coppery bronze), usually darker (sometimes blackish) terminally; other rectrices brownish gray (rarely partly chestnut on inner webs) basally, steel blue subterminally, and tipped with white (broadly on lateral rectrices) ; remiges slate-blackish or dusky, faintly glossed with violet-bluish; under parts pale brownish gray, paler (sometimes dull white) on chin and throat, passing into white on abdomen and anal region, the sides some- times slightly intermixed with metallic bronze or bronze-green; under

tail-coverts pale gray centrally, margined with white; bill, etc., as in


  1. A few specimens have the basal half of the lateral rectrices mostly chestnut-rufous, but these I think are immature males; one of them certainly is, the collector having taken pains to emphasize the determination of sex.
  2. Seventeen specimens.
