Small Trochilide (length about 65-70 mm.) related to Selasphorus 
but differing in form and coloration of the tail in the adult male, 
which is slightly rounded, with rectrices broadly rounded at tip, the 
lateral rectrices with basal half (more or less) cinnamon-rufous, suc- 
ceeded by a black band and white terminal spot; gorget with feathers 
rather more strongly individualized and relatively longer, especially 
the lateral ones. 
Bill about as long as head or slightly shorter, slender, straight, 
nearly terete; culmen rounded, slightly contracted or indistinctly 
ridged at extreme base; tomia smooth; mandible with the usual 
lateral median groove. Nasal operculum hidden by appressed frontal 
feathering, which anteriorly extends beyond nostrils, forming a very 
short obtuse point or antia on each side of culmen. Tarsus feathered, 
except along posterior side; outer toe slightly shorter than middle 
toe, the inner toe decidedly shorter, hallux (apparently) shorter than 
outer toe. Wing about three times as long as exposed culmen, the 
outermost primary, or two outermost, longest, the outermost nar- 
rower and abruptly more or less attenuated (but not acuminate) 
terminally. Tail about three-fifths as long as wing, rounded, the
