Note 23 — THE MISSOURI RIVER JOURNALS 1843 (Continued)

The fact that the Antilocapra americana does shed its horns was not satisfactorily established till several years after 1843. It was first brought to the notice of naturalists by Dr. C. A. Canfield of California, April 10, 1858, and soon afterward became generally known. (See Proc. Zoöl. Soc. Lond. 1865, p. 718, and 1866, p. 105.) Thereupon it became evident that, as Audubon says, these animals are not true Antelopes, and the family Antilocapridæ was established for their reception. On the whole subject see article in Encycl. Amer. i., 1883, pp. 237-242, figs. 1-5.—E. C.
