Eutoxeres salvini, Gould, Ann. Mag. Nut. Ili.st., 4th ser., vol. i, p. 458 (18C8), e.\ Vcragua. 



Hah. Costa Rica (eastern side), Vcragua, Columbia. 



Adult. Top of head and occiput brownish-black, fearhcrs tipped slightly with 

 buff. Upper parts dark .shining green; wings purple; under par's brownisii-black, 

 striated with buffy-white on the throat and breast, pure while on abdomen and 

 flanks. Median reprices shining dark green tipped with white. Lateral ones 

 dark green on outer webs, brownisli-green on inner, and broadly tipped witlr white. 

 Maxilla black; mandible Hesh-color. Total length, b-^'^ in. Wing, 3 in. Tail, 

 2j?g in. Culmen, l^^g in. 



I cannot perceive that the difference of coloration pointed out by Mr. Gould is 

 of sufficient importance to separate the Vcraguan birds specifically from those of 

 Columbia, and have therefore placed the E. fMlcini as a synonym of E. aquila. 



2. Eutoxeres heterura. 



Eutoxeres heterura, Gould, Ann. Mag. Nat. Hist., 4th ser., vol. i, p. 455 (ISfiB). 



Hah. Ecuador. 



Exactly like the preceding, E. aquila, except that the striaj upon the feathers of 

 the under parts are bright buff. This difference is apparently constant. Dimensions 

 the same. 



3. Eutoxeres condamini.

Hab. Ecuador. 



Easily distinguished from the other ^wo species of the genus, by the coloring of 

 the rectrices. The median ones are dark shining green, tipped willi white ; next 

 on either side, blackish-brown tipped with white, remainder deep buff, graduating 

 into white at the tips. Total length, 6 j% in. Wing, 8 in. Tail, 2 j'^ in. Culmen, 

 ly^g in. Description taken from the type in my collection.
