[25] Scops asio, var. enano, Lawrence, MSS. This well-marked race is founded upon two specimens,—one from Mexico, in the cabinet of Mr. Lawrence, and another from Guatemala, in the collection of the Boston Society of Natural History. They are exactly similar in colors; but, as might be expected, the more southern specimen is the smaller of the two. This form very closely resembles the S. atricapilla (Natt.) Steph. (Temm. Pl. Col. 145), but may be readily distinguished by the haired toes, they being perfectly naked in atricapilla. The latter species is found as far northward as Mirador.

[26] Scops semitorques, Schlegel, Fauna Japonica, t. 8. For the privilege of comparing specimens of this bird with S. kennicotti, I am indebted to the courtesy of the officers of the New York Museum, who kindly sent the fine specimens of that museum for examination.
