The Rev. Dr. Bachman, of Charleston, S. C., has fully established the identity of the two, and we have fully confirmed the accuracy of his observations (in Aud. Orn. Biog., V. p. 392). The young birds, as stated by him, are red when fully feathered, or nearly so; but we have observed that previously they are transversely striped with brown and white, with but little tinge of red, and presenting a general appearance somewhat like the adult mottled bird. They pair and breed in the red plumage, and it is not unusual to find a mottled male and red female associated, or the reverse. According to Dr. Bachman, the perfect plumage is assumed at the age of two years. Intermediate specimens, impossible to be referred absolutely to either of the plumages, are not uncommon. This bird holds its place throughout the country in spite of the constant destruction of the woodlands; and though universally known and scarcely regarded favorably by our people, is seldom molested. Its food is principally insects. 2. Scops McCallii. Cassin. _New species._ (July, 1854.) The Western Mottled Owl. In form and general appearance like the preceding (_S. asio_), but much smaller; short and robust; wing with the fourth quill longest; tail short, slightly curved inwards; tarsi rather long, fully covered; toes partially covered with long hair-like feathers. Adult. _Male._—Much resembling in color the adult of the species immediately preceding, but darker; entire plumage above, ashy-brown, nearly every feather with a longitudinal stripe of brownish-black, and with numerous irregular transverse lines and points of the same; under parts, ashy-white, every feather with a longitudinal stripe of brownish-black, and with well-defined but irregular transverse lines of the same; flanks and sides tinged with pale fulvous; quills brown, with several transverse bands of pale reddish-white, assuming the form of quadrangular spots on the outer webs, and pale reddish ashy on the inner webs; tail, ashy-brown, with about ten narrow transverse bands on all except the two central feathers, well defined on the inner webs; scapular feathers and some of the greater coverts of the wings, edged with white; bill greenish horn-color, light yellowish at the tip; irides, yellow. Dimensions. Total length, 7½ to 8 inches; wing, 6; tail, 3 inches. _Male._ Hab. Texas (Mr. Schott); Northern Mexico (Lieut. Couch). Spec. in Mus. Acad., Philada., and Nat. Mus., Washington city. Obs. This species very considerably resembles the adult or grey plumage of the _Scops asio_, but is uniformly much smaller and darker in color. The transverse lines on the under surface of the body are better defined and more numerous. It also somewhat resembles _Scops choliba_ of South America, under which name we suppose the female of the present bird to be alluded to by Mr. Lawrence, in Annals N. Y. Lyceum, VI. p. 4.
