Molossus mexicanus Saussure, Rev. et Mag. de Zoöl., 12:283, July, 1860, type from Cofre de Perote, 13,000 feet, Veracruz.
Tadarida mexicana, Miller, Bull. U. S. Nat. Mus., 128:86, April 29, 1924.
Range.—Statewide.
Specimens examined, 12: nos. 100100-100111, distributed by localities as follows: 1 mi. N Zamora, 5,450 ft., 1; 3 mi. N Pátzcuaro, 6,800 ft., 3; 3 mi. NW Pátzcuaro, 6,700 ft., 3; Isla Janitzio, Lago de Pátzcuaro, 6,600 ft., 5.
Remarks.—This species is widespread in México, ranging from sea level to high elevations as at the type locality. In Michoacán most of our specimens were shot as they flew about at early dusk. The five from Isla Janitzio were shot as they clung to the roof of a cave along with scores of other individuals of the same species.

Eumops underwoodi Goodwin, Amer. Mus. Novitates, 1075:2, June 27, 1940, type from El Pedrero, 6 km. N Chinaela, approximately 3,000 ft. elevation, Dept. La Paz, Honduras.
Range.—Known only from Tancítaro Mtn.
Specimen examined, 1: no. 89461, Univ. Michigan Mus. Zoöl., from Rancho Escondido, 2 mi. N Apo, Tancítaro Mtn., ♀ ad. with much worn teeth, taken June 11, 1945, by W. H. Burt.
Remarks.—Selected measurements of this specimen are: Total length, 158; ear from notch, 32; mastoid breadth, 16.1; width across crowns of M3, 12.6; maxillary tooth-row (from anterior face of canine above cingulum to posterior face of M3), 11.8. The total length is less than in E. underwoodi or than in Eumops sonoriensis Benson (1947:133); the other measurements given above exceed those of E. sonoriensis and equal or approach those of E. underwoodi. The ears seem not to be connected across the forehead; the color is near (l) Bister above and slightly lighter on the underparts.
