Length (of skin) about 5 inches. Anterior feathers of crest, cinereous, succeeding and most elongated, black, others margined with white, short occipital feathers black. Throat black, line commencing behind the eye, thence curving and uniting with the space of the same color on the throat, black. Line above the eye running into the crest and around on the neck, white. Entire plumage above cinereous, tinged with olive, below ashy white, bill and feet dark. Hab. Texas. Spec. in Mus. Acad. Philada. Obs. This species considerably resembles _Lophophanes cristatus_, (Linn.) a common European bird. I have no doubt that the names given above are synonymous; that applied by us being about one month later than the publication of the description by Bonaparte as cited. III. GENUS PSALTRIA. Temminck. Pl. Col. III. Bill very short, thick, upper mandible curved, entire, nearly of the same thickness as the lower, nostrils basal, concealed by projecting feathers, wings rather short, first quill spurious, fourth and fifth longest and nearly equal, tail long and slightly wedge-shaped. Tarsi long and slender, feet rather strong, claws curved and acute, that on the posterior toe strongest. Not crested, colors of all known species principally cinereous and white. This genus was established by the celebrated naturalist Temminck, of Leyden, (in Planches Coloriees, vol. iii.) with a little bird as its type named by him _Psaltria exilis_, which inhabits Java. The bird discovered by Dr. Townsend in Oregon, and now well known to American Ornithologists as _Parus minimus_, Townsend, not only belongs to this genus, but only materially differs in size from _Psaltria exilis_. Temm. Its colors and general appearance much resemble it. The American species are: 1. Psaltria minima. (Townsend) Townsend’s Chickadee. Parus minimus. Townsend, Jour. Acad. Philada. vii. p. 199. (1837.) Length (of skin) about 4 inches. Head above deep cinereous, inclining to purplish brown, body above cinereous, with a tinge of olive. Throat and breast whitish, abdomen and flanks cinereous, tinged with purplish brown, bill and feet black. Female rather smaller. Hab. Oregon and California. Spec. in Mus. Acad. Philada. Obs. As frequently turns out to be the case with birds to which such names as minor and minimus are applied, this little bird is considerably _larger_ than its near relative, _P. exilis_, Temm. which otherwise it much resembles. It is now frequently brought in collections from California. 2. Psaltria melanotis. (Sanbach.) The black-eared Chickadee. Parus melanotis. Sandb. Proc. Brit. Ass. for Adv. Sci. vi. p. 99. (1837.) “Parus melanotis. Sandb.” Hartlaub, Rev. Zool. 1844, p. 216. Psaltriparus personatus. Bonaparte, Comptes Rendus Acad. Paris, xxxi. p. 478. (Sept. 1850.)
