Ch. Bill about as long as the head, straight, 

 wide at base graduating to a point at the tip. 

 Frontal feathers not projecting on to the culmen. 

 Wings long and broad for their length. Tail

 E. nigriventris, Lawr. 



moderate, slightly rounded. Under tail coverts 

 reaching half the length of the rectrices. Feet 

 small; tarsi partly clothed. Sexes entirely unlike 

 in the color of their plumage. 



Range. Costa Rica and Vcragua. 



But one species is known, a miniature EuPHE- 

 RUSA in many particulars, which seems to find its 



natural place between the members of that genus and those of Elvira. The term 

 Clotho, bestowed on this species by j\I. Mulsant, having been previously employed 

 in various branches of zoology, I propose in its place Callipharus.

In the style of coloration observed in the wing, this species resembles those of 

 the next genus. 



The members of the genus Eupheru.sa arc birds of moderate size, differing chiefly 

 in the coloration of their tails. Thev resemble eacli other in the hues of tlieir
