7 2 THE CONDOR I VoL. V examples from the same general region (i.e., Utah and Montana), one of them be- ing actually from the same locality (Fort Bridger)." It would appear from the foregoing quotations that the chief objection to the recognition of a Pacific coast race is the inconstancy and comparative slightness of the distinguishing characters. For the past thre? years I have taken pains to personally gather a series of California yellow warblers, and these, together with similar material kindly loaned me by Mr. T. J. Hoover and Mr. F. S. Daggett, amount to ninety seven specimens. The former has also provided a series of eastern birds, and the Na- tional Museum, through Dr. C. W. Richmoud, has granted me the use of a most requisite series of yellow warblers from the Rocky Mountain region. Even a superficial view of the above material suffices to impress one with the conspicuous peculiarities of the California race, as distinguished from the bird of the Rocky Mountains and eastward. These differences are surely of as much value as those marking the lutescent warbler, long-tailed chat, golden pileolated warbler, Calaveras warbler (much more so!), or many others of the better-known subspecies that could be mentioned. As to the application of the name rnorcomi the remarks of Mr. Brewster seem wholly correct. Coale's name was based on individual extremes of Z)endroica lira ?estiva, as well as on examples of the actually different race from West of the Sierra Nevada Mountains. The type was undoubtedly one of the former, hence the necessity of retiring the name morcomi to the synonymy of ?estiva, and sup- plying the California race with a new name. This I do, commemorating in the name selected an ornithologist toward whom we feel grateful for his extensive and careful work on western birds. Dendroica a?stiva brewsteri new name. Su?SPECIX*IC CHARA?TERs.--Resembling Oendroica r?sliva r?sliva, from which it differs in smaller size, paler (or less brightly yellow) coloration, and, in the male, narrower streaking on un- der surface; differs from Dendroica restira rubi?inosa in much smaller size and yellower colora- tion, and from Dendroica restira sonorana in smaller size and much darker coloration. TYPES.--(? ad.; No. 47oi Coil. J. G.; Palo Alto, California; May I8, I9OI. ?? ad.; No. 4154 Coil. J. G.; Palo Alto, California; May I4, I9OO. (The types were carefully selected to represent the average manifestation of subspecific char- acters.) DESCRIPTION OF TYPEs.--fl[ale. Whole mantle and hindneck yellowish olive-green (the feathers with faintly more yellowish edgings), becoming lemon yellow on rump, and subdued Indian yellow on crown and forehead; wings and tail "fuscous" edged with canary yellow; sides of head and throat lemon yellow; rest of lower parts deepening into gamboge yellow; breast and sides "narrowly" streaked with chestnut (approaching liver brown), these streaks approximating one millimeter broad at widest. Female. Upper parts olive-green, becoming more yellowish on rump and forehead; lower surface pale canary yellow, weakening to primrose yellow on lores, throat and belly; sides faintly and very narrowly streaked with pale liver brown.

Specimens examined from Oregon: Salemi; and California: Siskiyou, Battle Creek, Redding, Amador City, Palo Alto ?, Santa Cruz, Los Angeles ?, E1 Monte, Pasadena ?. INDIVIDUAL VARIATION.--In the matter of streaking in the male there is surprising constancy, Among the fifty-four adult males of brewslerz at hand, but one specimen (No. I849 , Coil. T. J. H., Palo Alto, May 7, I898.) is so heavily streaked as to resemble in that respect even the lightly streaked extremes among thirty-seven males of true r?sliva. This specimen is also brighter yel- low than usual, and closely matches No. IO983, Coil. U.S. N.M. (Fort Bridger) which is a topo-
