1864. _Mormops megalophylla_ Peters, Monatsb. preuss. Akad.
Wiss., Berlin, p. 381, type from southern Mexico.
_Distribution in Tamaulipas._--Throughout state, except
possibly west of the Sierra Madre Oriental.
Specimens from the Sierra de Tamaulipas were taken in mist nets in
which _Pteronotus rubiginosus_, _Lasiurus borealis_, or _Centurio
senex_ also were captured. The specimen from Rancho Santa Rosa was shot
as it flew at a height of six feet.
Tamaulipan specimens of _Mormoops megalophylla_ are here assigned to
_M. m. megalophylla_ instead of to _M. m. senicula_ following Villa and
Jimenez (1961:503), who regarded _senicula_ as indistinguishable from
_megalophylla_.
Weight of four specimens from the Sierra de Tamaulipas averaged 16.2
(15-18) grams.
_Records of occurrence._--Specimens examined, 5: Sierra de
Tamaulipas, 3 mi. S, 16 mi. W Piedra, 1300 ft., 2; Sierra de
