An adult male captured in a mist net set in a forest clearing at Santa
Maria de Ostuma, 1250 m, Matagalpa, represents the first record of this
bat from Nicaragua. The testes of our individual, taken on 1 July 1966,
were 6 mm in length. Externally and cranially our Nicaraguan example
closely resembles specimens of _C. auritus_ from Veracruz and the
Yucatan Peninsula. Handley (1966b:762) and Starrett and Casebeer
(1968:12) expressed doubt as to the validity of the currently used
subspecific names in this species. Comparisons of cranial and external
measurements of the material at hand with those given in various
published accounts--Burt and Stirton (1961), Starrett and Casebeer
(1968), and Thomas (1905), for example--reveal little variation. Until
additional information is available (especially as concerns the South
American races), however, we tentatively apply the subspecific name _C.
a. auritus_ to Middle American populations.
