_Records_: Cueva de la Sepultura, 7.5 km. NNW and hence 7 km. SSW (_via_ highway) Cd. Victoria (Malaga and Villa, 1957:543); 5 mi. NE Antiguo Morelos, near El Pachón (de la Torre, 1954:114); El Pachón (Martin and Martin, 1954:585); Cueva de Quintero, 4 km. SSW Quintero (Malaga and Villa, 1957:543). =Natalus stramineus saturatus= Dalquest and Hall Mexican Funnel-eared Bat 1949. _Natalus mexicanas saturatus_ Dalquest and Hall, Proc. Biol. Soc. Washington, 62:153, August 23, type from 3 km. E San Andrés Tuxtla, 1000 ft., Veracruz. 1959. _Natalus stramineus saturatus_, Goodwin, Amer. Mus. Novit., 1977:7, December 22. _Distribution in Tamaulipas._--Central and southwestern parts of state. All specimens examined were obtained from caves. At Cueva la Esperanza, approximately 400 individuals were found along with individuals of _Desmodus rotundus_; _Natalus_ and _Desmodus_ also were collected together in a cave approximately 30 yards deep three miles south and 14 miles west of Piedra, and in a cave six and a half miles north and 13 miles west of Jiménez, the northernmost locality from which _N. stramineus_ is presently known. Tamaulipan specimens do not differ significantly in external or cranial measurements in comparison with the specimens from Veracruz reported by Dalquest and Hall (1949:154), but do differ in color. Most are in the gray phase and are Avellaneus (grayish with yellowish hairs mixed) instead of Clay Color as are specimens from Veracruz; those few in the red phase are between Clay Color and Tawny-Olive instead of between Burnt Sienna and Chestnut. By consequence, bats from Tamaulipas resemble in color the smaller _N. s. mexicanus_ of western México to a greater degree than they resemble _N. s. saturatus_, but I follow Goodwin (1959:7). Dalquest and Hall (1949:154) reported the specimen from eight kilometers northeast of Antiguo Morelos as from San Luis Potosí, from which state the collector (Dalquest) evidently thought it had originated. Actually the place eight kilometers northeast of Antiguo Morelos is in Tamaulipas. _Records of occurrence._--Specimens examined, 64: 6.5 mi. N, 13 mi. W Jiménez, 1250 ft., 14; Cueva de la Esperanza, 6 km. SW Rancho Santa Rosa, 360 m., 20; Sierra de Tamaulipas, 3 mi. S, 16 mi. W Piedra, 1400 ft., 7; 3 mi. S, 14 mi.
