A single individual of this rare species was procured by Gap-tain Stansbury. This bird was first described by Edward Harris, Esq., from a specimen shot on the Yellow Stone River in July, 1843, and is the largest of the American species of true Black- cap Titmice, three in number. It is not improbable that two species may be confounded under the name of septentrionalis, as this specimen is quite different from one collected by R. H. Kern, in New Mexico. The latter is, however, too much mutilated and faded to serve as a proper standard of comparison, for which we must wait to get better specimens. 6. STURNELLA NEGLECTA, Audubon.- Western Lark. Sturnella neglecta, Aud. Biog. 2d ed. VIL 840 ( 1848). The distinctions between the old Sturnella ludoviciana and the present species are quite obscure. A specimen from Fort Union, presented to us by Mr. Audubon, agrees with the published characters in nothing but the bands on the middle tail- feathers, which replace the scolloping seen in S. ludoviciana. The tail is quite as much rounded, and the bill of the same size. The Salt Lake bird has the tail more square, and the bands on the middle tail- feathers still more distinct than in the one from Fort Union. The size is fully as large as that of the common species. The specimen was shot March 18, 1850, in the cafions between Salt Lake City and the Hot Springs. This lark utters a single rough note like that of the European starling. Length 10} inches.
