Very small, short-tailed, broad-gaped, frugivorous Tanagers, with

 or else with only the pileum and hindneck })lue, the remaining upper 

 surface plain dark steel blue, glossy blue-black, or olive-green. 



Bill short (exposed culmen about half us long as tarsus), triangular 

 in vertical profile, ))ut extremely variable as to proportionate length, 

 breadth, and depth, the extremes, connected by intermediate forms, 

 being represented by three types, as follows: (1) Bill very broad and 

 depressed, its width at base equal to length of exposed culmen, its 

 lateral outlines distinctly sinuate (convex basally and concave ter- 

 minally); depth of bill at base equal to only about half its width. 

 (E. musica, type of the genus.) (2) Bill slender, almost terete, its
