1866. _R[hogeessa]. tumida_ H. Allen, Proc. Acad. Nat. Sci.
Philadelphia, 18:286, type from Mirador, Veracruz.
_Distribution in Tamaulipas._--Southeastern part of state.
Specimens obtained from the vicinity of La Pesca were shot as were some
from the Sierra de Tamaulipas. Others from the Sierra de Tamaulipas
were taken in mist nets that were stretched across a small pool in an
arroyo; _Eptesicus fuscus_, _Myotis velifer_, _M. keenii_ and
_Nycticeus humeralis_ were captured in the same nets.
Females evidently bear young in Tamaulipas in April and May. Fourteen
of 15 females collected at La Pesca in May were lactating, as were five
of 31 taken in the Sierra de Tamaulipas in June. The weight of 46
females averaged 5.5 (4-7) grams, and that of nine males, 4.5 (4-5)
grams.
Comparison of specimens from Tamaulipas with individuals from Veracruz
reveals little difference in general color between the two samples.
Most Tamaulipan specimens examined are dull yellowish brown, but some
are darker. Goodwin (1954:6) reported a specimen from Santa Maria as
being dark brown. Measurements of 10 females (see below) from the
Sierra de Tamaulipas average a little larger than those reported by
Miller (1897:123-124), Hall (1952:232), and Goodwin (1958:10-12). I
follow the last author in using the specific name _R. tumida_ for this
bat.
_Measurements._--Average and extreme measurements of 10
females from the Sierra de Tamaulipas are as follows: 80.1
(78-83); 35.5 (33-37); 7.9 (7.5-8.0); 13.1 (13-14); length
of forearm, 31.9 (30.6-33.0); greatest length of skull, 13.4
(13.1-13.8); zygomatic breadth, 8.6 (8.2-8.8); mastoid
breadth, 5.6 (5.3-5.8); breadth across M3, 5.7 (5.5-6.0);
length of maxillary tooth-row, 4.8 (4.7-4.9).
