Colors. Entire upper parts light brown, slightly tinged with rufous on the rump; quills brownish black, edged on their outer webs with lighter; tail brownish-black, with a reddish tinge, lighter on the under surface; an obscure ashy white superciliary line; auricular feathers dark brown, with central white lines; throat white; breast and sides light brown, tinged with ashy and fulvous; middle of the abdomen, flanks and under tail-coverts rufous, darker on the last; bill black; tarsi lighter; “irides hazel.” Sexes alike? Hab. California. Spec. in Mus. Acad., Philadelphia, and Nat. Mus., Washington. Obs. There are two other species of this genus, both of which the present bird somewhat resembles, but it can easily be distinguished on comparison by its larger size. From the published descriptions the different species cannot be distinguished so readily, on account of their similarity of form and general characters. Dr. Gambel regarded this bird as identical with a species mentioned and figured by the distinguished, though unfortunate navigator, La Perouse, and published in “Voyage de La Peyrouse autour du Monde,” Atlas, pl. 37 (Paris, 1797), under the name of “Promerops de la California Septentrionale.” Under this impression, Dr. Gambel gave this bird its specific name, _redivivus_. Whether it is the fact, however, that the figure in La Peyrouse represents the present bird, admits of some doubt. To us it is much more like _Toxostoma curvirostris_, a smaller species. [Illustration: Plate 43 The Vermilion Flycatcher Cardellina rubra (_Swainson_)] CARDELLINA RUBRA.—(Swainson.) The Vermilion Flycatcher. PLATE XLIII. Males. Of this brilliant-plumaged little Flycatcher, we have, we regret to say, but little information. It has been known as a Mexican bird since 1827, when specimens were sent to Europe for the first time by Mr. William Bullock, a Fellow of the Linnæan Society of London, who was then resident in Mexico, but has as yet been obtained once only within the limits of the United States. It was received in a collection made in Texas, and containing many interesting species, by Mr. J. P. Giraud, an accomplished and active ornithologist of the city of New York, and was by him first introduced as entitled to a place in the ornithological fauna of this country. Since that period no one of the several American naturalists who have visited Texas, has had the good fortune to meet with it. This bird was first described by Mr. Swainson, in the Philosophical Magazine, new series, I. p. 367, but little or nothing more is said of it than on the authority of Mr. Bullock, it is stated to be an inhabitant of the table lands, and that the specimens in his collection were obtained in the vicinity of Valladolid. Mr. Bullock himself, in his interesting book, “Six Months in Mexico,” does not allude to it.
