booted (nonsciitellate) or with scutella of acrotarsium faintly defined; middle toe, with claw, slightly more than three-fifths as long as tarsus (as long as or slightly longer than whole culmen); outer toe, without claw, reaching to or slightly beyond subterminal articulation of middle toe, the inner toe slightly shorter; hallux shorter than inner toe, considerably but not conspicuously stouter; basal phalanx of middle toe united for about half its length to outer toe, for loss than half to inner toe; claws rather short, slightly curved, that of hallux decidedly shorter than the digit. Plumage full, soft, and blended, that of rump and flanks (especially the former) more elongated and lax, that of pileum short, with feathers distinctly outlined; a very small naked postocular space.
Coloration. — Above olive (more grayish or dusky, on pileum) the back sometimes streaked with buff, the wings sometimes varied with buff or tawny; a buff orbital ring (indistinct or obsolete in H. dives); under parts with at least throat and abdomen white, the chest, sides, and flanks more or less buffy, ochraceous, or tawny, the first (at least) more or less streaked with black; sexes alike.
Range. — Nicaragua to Cayenne, southeastern Brazil, and western Ecuador.
