This species is allied to, and in some respects intermediate between, palmeri and H. cincrens : its closest relationships being decidedlywith the latter, though the appearance of the under parts is altogether dif-ferent. It is distinguished from palmeri in being much smaller, with a much.

In the latter, the bill, though of uearly the same length,is more curved; the tarsus is not longer than the middle toe and claw ; thethird-sixth quills of the wing are about equal and longest, the secondbeing about equal to the eighth ; while the under parts are as distinctly andheavily spotted as those of H. rii/us itself. The two are of about the samesize, and in the coloration of the upper parts are much alike. While fullyrecognizing the close relationships of R. hendirii to H. cinereus—in fact, hav-ing insisted upon them from the outset, when it was assumed that the birdw
