taken on March 12, 1943, from a crevice in the wall of an abandoned chapel where 35 or more individuals of both sexes were living. Miller (1897:59) records the species from Pátzcuaro and Miller and Allen (1928:91) record it from there and also from Lake Chapala, La Palma, Acámbaro (now in Guanajuato) and Negrete.

Myotis thysanodes thysanodes Miller

Fringed-tailed Myotis; Spanish, Murciélago Colirugosa

Myotis thysanodes Miller, N. Amer. Fauna, 13:80, October 16, 1897, type from Old Fort Tejon, Kern County, California.

Remarks.—In the original description five specimens are recorded from Pátzcuaro and Miller and Allen (1928:127) mention the same locality of occurence.

Myotis californicus mexicanus (Saussure)

California Myotis; Spanish, Murciélago de California

V[espertilio]. mexicanus Saussure, Rev. et Mag. de Zoöl., 12 (ser. 2):282, 1860, type from somewhere in the warmer part of the state of México.

Myotis californicus mexicanus, Miller, N. Amer. Fauna, 13:73, October 16, 1897.

Remarks.—Specimens from Pátzcuaro are recorded by Miller and Allen (1928:160).

Eptesicus fuscus miradorensis (H. Allen)

Big Brown Bat; Spanish, Murciélago Fusco

S[cotophilus]. miradorensis H. Allen, Proc. Acad. Nat. Sci. Philadelphia, p. 287, 1866, type from Mirador, Veracruz.

Eptesicus fuscus miradorensis, Miller, N. Amer. Land Mamm., 1911, p. 62, December 31, 1912.

Lasiurus borealis mexicanus (Saussure)

Red Bat; Spanish, Murciélago Rojizo

A[talapha]. mexicana Saussure, Rev. et Mag. de Zoöl., 13(2):97, March, 1861, type probably from Veracruz, Puebla or Oaxaca.

Lasiurus borealis mexicanus, Miller, N. Amer. Fauna, 13:111, October 16, 1897.

Remarks.—This specimen, a male with much worn teeth, answers well to the description of L. b. mexicanus except that the minute premolar between the canine and fourth premolar is missing on each side of the upper jaw. This, however, seems the less remarkable after examination of 18 skulls of L. b. borealis from the United States in two of which these minute premolars are likewise absent; one of the two specimens from the United States has unworn teeth and the other much worn teeth.

Lasiurus cinereus cinereus (Beauvois)

Hoary Bat; Spanish, Murciélago Pardo

Vespertilio cinereus (misspelled linereus) Beauvois, Catal. Raisonné Mus. Peale, Philadelphia, p. 18, 1796, type locality, Philadelphia, Pennsylvania.

Lasiurus cinereus, H. Allen, Monogr. N. Amer. Bats, Smithsonian Misc. Colls., 7(1): 12, June, 1864.

Corynorhinus rafinesquii mexicanus G. M. Allen

Long-eared Bat; Spanish, Murciélago Narigudo

Corynorhinus megalotis mexicanus Allen, G. M., Bull. Mus. Comp. Zoöl., 60:347, April, 1916, type from "near Pacheco," Chihuahua.

Corynorhinus rafinesquii mexicanus, Miller, U. S. Nat. Mus., Bull., 128:83, April 29, 1924.

Corynorhinus macrotis pallescens, Miller, N. Amer. Fauna, 13:52, October 16, 1897.

Remarks.—Miller (1897:53) recorded one specimen from Pátzcuaro and Allen (1916:349) merely alludes to Miller's record.

Tadarida mexicana (Saussure)

Mexican Free-tailed Bat; Spanish, Murciélago Coludo

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.

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 underwoodi Goodwin

Mastiff Bat; Spanish, Murciélago Mastin

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.

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.

The specimen is clearly intermediate in size, as it also is geographically, between Eumops underwoodi underwoodi Goodwin and Eumops underwoodi sonoriensis Benson and gives basis for arranging these two named kinds as subspecies of a single species as Benson (1947:134) suggested might prove to be necessary. We are not certain whether this specimen should be referred to the subspecies underwoodi or sonoriensis and probably this uncertainty will remain until the range of individual variation in underwoodi is known.

Procyon lotor hernandezii Wagler

Raccoon; Spanish, Mapache; Tarascan, Apátze (Apatz)

Pr[ocyon] hernandezii Wagler, Isis, 24:514, 1831, type from Valley of México, according to Nelson and Goldman (Proc. Biol.
