RAYMOND HALL When Gerrit S. Miller, Jr., published his "Revision of the North American Bats of the Family Vespertilionidae" (N. Amer. Fauna, 13:1-140, 3 pls., 39 figs. in text, October 16, 1897), the red bat, _Lasiurus borealis_, was known from the southern half of Mexico but he did not know that the hoary bat, _Lasiurus cinereus_, also occurred there. Therefore, the name _A[talapha]. mexicana_ Saussure (Revue et magasin de zoologie, 13 (ser. 2): 97, March, 1861) that clearly pertained to a lasiurine bat, almost certainly from southern Mexico, was applied by Miller (_op. cit._: 111) to the red bat as a subspecific name. Subsequently, the hoary bat, _Lasiurus cinereus cinereus_ (Beauvois 1796), was shown to occur in southern Mexico. For example, an adult male _L. c. cinereus_ was obtained on May 6, 1945, by W. H. Burt from the Barranca Seca in the State of Michoacan (see Hall and Villa, Univ. Kansas Publ., Mus. Nat. Hist., 1:445, December 27, 1949). Because two, instead of only one, species of _Lasiurus_ are now known to occur in the general part of Mexico visited by Saussure, it has seemed desirable to re-examine the application of the name _A[talapha]. mexicana_ Saussure which that naturalist proposed along with a description as follows: Long inrolled tail; femoral patagium as in the vespertilios. Teeth 4/2, 1/1, 4/5 or 5/5. _A. mexicana_ Valida. Molar teeth 4/5. Head and throat with a tendency toward fulvous, mouth and chin dark. Ears small and rounded, black, exterior at the base dark and hairy, interior with the anterior margin and an area in the middle yellow-haired. Back chestnut, above [hairs apically] grayish, below [hairs lower down] reddish, everywhere marbled with white. Tibiae, feet and the femoral patagium reddish marbled with white. Venter dusky-gray, with hairs at the apex and on the breast whitish, on the abdomen with tendency toward fulvous. White spot on humerus. Wings black; underneath the arm and the superior half of the wing yellow-haired. Above [on the upper side] with three whitish spots on the base of the thumb and fifth finger situated in the angle of the elbow.--Forearm length 53 mm. [Above is translation from the Latin original.]
