1949. _Natalus mexicanas saturatus_ Dalquest and Hall, Proc.
Biol. Soc. Washington, 62:153, August 23, type from 3 km. E
San Andres 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 Jimenez, 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 Mexico 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 Potosi, from
which state the collector (Dalquest) evidently thought it had
originated. Actually the place eight kilometers northeast of Antiguo
Morelos is in Tamaulipas.
