Leaden-gray, rather brighter and more ashy on the crown, but without marked contrast, faintly glossed with olive on rump ; a conspicuous white line from nostril to and around eye, and below this a dusky loral stripe ; below, pure white, sides of neck aud breast shaded with color of the back, tlanks, axillars and crissum with a mere trace of olivaceous, or none; wing and tail dusky, with conspicuous pure white edgings and cross-bars. Size of the last or rather larger ; bill nearly Plumbeousviieo. J; tarsus §; middle toe the same; spurious quill about f, one-third as long as the second quill. Central Plains to the Pacific, U. S., and especially Southern Rocky Mountains, where it is abundant. A large stout species, a near ally of soUlarius, but nearly all the olivaceous of tiiat species replaced by plumbeous, and the yellowish by white, so that it is a very different looking bird. It may prove onl^' a variety, but I have seen no intermediate specimens, and cannot reconcile the obvious discrepancies, upon this supposition. Coues, Pr. Ac.
