Uppor part bright bronze-green, with a slight coppery tinge on 

 the head ; cliin white ; throat, breast, and sides of the neck bright 

 metallic grass-green ; flanks and abdomen dull green ; middle of 

 abdomen, vent, and under tail-coverts pure white; median rec- 

 trices bronze-green ; lateral purplish black, the edges of the outer 

 webs and tips bronze-green ; wings purplish brown ; bill flesh- 

 colour (perhaps red in life) with a dark tip. Total length 3'5 inches, 

 wing 3-12, tail 1-5, bill (culmen) 0-75." (Elliot, I. s. c.) 



I do not recognize any specimens answering to this description in 

 the Museum Collection. The pure white under tail-coverts indicate 

 its relationship to A. tephrocephala.

Adult male. Very similar to that of A. tephrocephala, but 

 decidedly smaller, and with the median rectrices darker above. As 

 in A. tephrocephala, the middle of the abdomen and under tail- 

 coverts are pure white. Total length about 3-4 inches, wing 2, 

 tail 1-15, bill 0-72. 



Mr. Elliot also gives as the habitat of this bird, Trinidad and 

 Guiana. I have not seen skins from either place.
