 claw, strongly decurved from base, narrowly rounded; gonys nearly 

 twice as long as mandiblular rami, faintly concave, narrowly rounded 

 or very indistinctly ridged; maxillary tomium mthout trace of sub- 

 terminal notch. Nostril longitucUnally ovate or sUghtly coma-

 rather short, much rounded, the longest primaries exceeding distal 

 secondaries by less than length of exposed culmen; fourth, fifth, and 

 sixth primaries longest, the eighth shorter than second, ninth very 

 much shorter than secondaries, and tenth (outermost) decidedly less 

 than half as long as sixth. Tail about one and a haK times as long as 

 wing, graduated for nearly half its length, the rectrices relatively 

 rather broad. Tarsus about one-fourth as long as wing, sUghtly but 

 decidedly longer than middle toe with claw, only the extreme upper 

 portion in front feathered.
