_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. _Range._--Known only from Tancítaro Mtn. _Specimen examined_, 1: no. 89461, Univ. Michigan Mus. Zoöl., from Rancho Escondido, 2 mi. N Apo, Tancítaro Mtn., [F] 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. 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. Soc. Washington, 44:17, February 21, 1931). _Procyon lotor hernandezii_, Allen, Bull. Amer. Mus. Nat. Hist., 3:176, December 10, 1890. _Range._--Statewide. _Specimens examined_, 2: no. 100113 from 10 mi. ESE Zamora, 5,500 ft., 1; no. 52220 from 15 kms. W Apatzingan, 1,040 ft., 1.
