Tamaulipas.
_Distribution in Tamaulipas._--Known only from southeastern
part of state.
Specimens from three miles south and 16 miles west of Piedra were found
in a crevice inside a cave. Two days previously _Desmodus rotundus_ and
_Natalus stramineus_ were obtained from the same cave. All other
specimens from the Sierra de Tamaulipas were caught in mist nets.
_Nycticeus humeralis_, _Myotis velifer_, _Eptesicus fuscus_, _Lasiurus
borealis_ and _L. intermedius_ were taken in nets that also captured
_T. laticaudata_.
All specimens taken (June 19-23) in the Sierra de Tamaulipas were

each, the embryos averaging 27.0 (25-28) mm. in crown-rump length; the
