274 TEOCHILID^. 



E. mpreiceps was described by Mr. Lawrence in 1866 from male specimens sent to 

 the United States National Museum by Carmiol from Barranca in Costa Rica ^- A 

 female from Tucurriqui liad 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 U. cMonura 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 Eica, where it inhabits the mountain -forests at 

 about an elevation of 3000 feet above sea-level.

HYPUROPTILA. 



Agyrtria, 8. Chalybura, Reich. Aufz. d. Col. p. 10 (1854). 

 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 Lam'pornis 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. isauroB and H. melanorrlioa are 

 restricted to Panama and Costa Rica and Nicaragua respectively.
