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,'^ black of subterminal portion 

 brightly glossed with bluish green, and under parts more extensively 

 and uniformly grayish, the sides without green spotting or inter- 

 mixtiu'e. 



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 browaiish gray on sides, flanks, and lower abdomen; under tail- 

 coverts dusky brownish gray, usually more blackish sub terminally, 

 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 (sldns), 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 i)ale 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.
