Jh. Bill longer than the head, turned,

 long and pointed. Tail slightly rounded. 

 Tarsi partly clothed. 



Range. Guiana. 



With a bill similar in structure to that 

 of the species in the preceding genus, the 



single member of the present one possesses also fiery metallic tail feathers, very 

 similar to those of the species contained in the genus immediately succeeding. It 

 seemed, therefore, that here was the proper place for it to occupy. The single 

 species is rather small, of a not ungraceful form, and brilliant plumage.
