274 TROCHILIDA. 
E. cupreiceps was described by Mr. Lawrence in 1866 from male specimens sent to 
the United States National Museum by Carmiol from Barranca in Costa Ricat. A 
female from Tucurriqui had for some time been in our collection; but we did not 
venture to describe it from such insufficient material. The resemblance of this species 
to EF. chionura is obvious; but at the same time its distinctive characters can readily 
be recognized in its more curved bill and coppery head. 
Its range seems confined to Costa Rica, where it inhabits the mountain-forests at 
about an elevation of 3000 feet above sea-level.

Hypuroptila, Gould, Mon. Troch. ii. t. 89 (May 1854). 
In this and the following genera of this section the bill is stouter than in the genera 
immediately preceding, but the ends of the tomia of the maxilla are not curved inwards 
to any great extent. In Hypuroptila and in Lampornis the culmen is feathered at the 
base, but the nasal covers are partially exposed, and the sexes are dissimilar. 
In Hypuroptila the under tail-coverts are large and full, and the rectrices are bronze 
or greenish-bronze—both characters by which it may at once be distinguished from 
Lampornis. 
The range of this genus extends from Nicaragua to Colombia and Venezuela. Of 
the five species all but one occur within our limits; H. tsawre and H. melanorrhoa are 
restricted to Panama and Costa Rica and Nicaragua respectively.
