ANTHRACOTHORAK 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,? 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).® 
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 subtermi- 
nally, 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 
@ 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.
