spondingly narrower; superciliary ochraceous and less clearly defined; throat 

 deeper in tone, oohraceous-buff rather than buff, its color spreading to the breast, 

 the sides of the head and auricular region; flanks and abdominal region more 

 ochraceous. Differs from iS. /. mvltostriata (Scl.) of the Bogota region, in being less 

 heavily margined with black below, the margins more even in outline, the throat- 

 patch much larger and paler, the upperparts browner, the frontal region less chest- 

 nut and less distinctly streaked.

Inhabits the Tropical Zone of the Pacific coast. Our ten specimens 

 differ from a single specimen of what I assume to be H. s. subulatus in their 

 deeper, more olivaceous underparts and the absence of shaft-streaks in 

 the crown and foreback.
