32. Helminthophila celata lutescens Ridgw. Western Orange-crowned Warbler.—A few were seen late in April near Tucson.
Although not perfectly typical of lutescens, both of the Orange-crowned Warblers obtained by Mr. Stephens are clearly referable to that race. They are not quite as yellow beneath as Nicasio (California) specimens, but they come within a shade of it, and are brighter by many shades than any of the same sex among my eastern examples; while in the vividness of the olive-green on the upper parts, they fully equal any of the California females. The supposed difference in the tail markings of these races does not hold in the series before me, for a male from Nicasio has the edging on the inner webs of the rectrices quite as broad and pure as that of any of the Florida ones. The loss of this character, however, would be of little consequence, as the two forms could be readily separated by the wide difference in their general coloring. Mr. Henshaw considers his Arizona specimens true celata, and lutescens is now for the first time announced from that Territory.
