Eriocnemis aurea sp. nov. 



E. ctipreiventri (Fras.) similis, sed minor, corpore toto, gula et pec- 

 tore exceptis, aureo-oeneo, caudae tectricibus longis prasinis, subcaudali- 

 bus cobaltinis plus minusve viridi marginatis, tibiarum pappis minoribus,

E. cupreiventris measures : wing, 62 mm. ; tail, 45 mm., bill 

 of equal length. The coloration of the specimen above described 

 differs so considerably from cupreiventris that it cannot be taken 

 for an individual variation. While cupreiventris is only slightly 

 tinted with bronze, aurea is covered with golden bronze all over, 

 and in part of a most lively tint, even on the shorter tail and 

 wing coverts. The throat and upper breast are lighter green 

 than in cupreiventris, and in certain lights washed with bronze 

 too, and each feather has a concealed white cross band as in E . 

 dybowskii Tacz. Further, the long upper tail-coverts are not 

 greenish blue, but green, and the under tail-coverts are not 

 violet, but cobalt blue, only in certain lights they are hya- 

 cinth-blue, some margined with green. The color of the wings 

 as well as of the tail is not as lively as in cupreiventris ; and, 

 finally, the white plumes on the thighs are much shorter and not 

 as abundant. The specimen cannot be taken for a young cu- 

 preiventris, being much more brightly colored on the whole 

 body, than the adult of this species.
