(2.9-3.2) mm; length of maxillary toothrow, 4.7, 4.7, 4.5, 4.3

Tadarida laticaudata yucatanica (Miller, 1902)

One adult male (testes 5 mm) of this free-tailed bat from Potosi, 5 m,
Chinandega, on the Cosigueina Peninsula, provides the only record of the
genus _Tadarida_ from Nicaragua. This specimen was netted after dark
over a small stream that flowed into the Bay of Fonseca approximately
200 yards below our nets (see account of _Noctilio leporinus_). Other
species taken in the same net included _Carollia subrufa_, _Sturnira
lilium_, _Eptesicus furinalis_, _Molossus ater_, and _Molossus
molossus_.

Selected measurements of the male are: total length, 92 mm; length of
tail, 31 mm; length of hind foot, 10 mm; length of ear, 15 mm; length
of forearm, 39.2 mm; weight, 10.3 gms; greatest length of skull, 17.2
mm; zygomatic breadth, 10.6 mm; postorbital constriction, 4.0 mm;
breadth of braincase, 8.6 mm; length of maxillary toothrow, 6.5 mm.

Eumops auripendulus (Shaw, 1800)

A broken skull (USNM 339917) of a female of this species from Hda.
Mecatepe [2 km N, 11.5 km E Nandaime, _ca._ 40 m], Granada, represents
the only known specimen of the genus _Eumops_ from Nicaragua. This bat
was obtained by M. K. Clark on 25 August 1964, but the conditions under
which it was captured are not known. Available cranial measurements
are: zygomatic breadth, 12.6 mm; breadth of braincase, 10.7 mm;
postorbital breadth, 4.3 mm; rostral breadth, 7.4 mm; length of
maxillary toothrow, 9.1 mm; length of mandibular c-m3, 10.0 mm.

_Specimens._--_Chinandega_: Potosi, 5 m, 21; 4.5 km N Cosigueina, 15
m, 2; El Paraiso, 1 km N Cosigueina, 20 m, 17; Hda. Bellavista, 720
m, Volcan Casita, 4; Hda. San Isidro, 10 km S Chinandega, 20 m, 2;
San Antonio, 35 m, 2. _Nueva Segovia_: Corozo, 15 km NNE Jalapa,

Only one specimen of this large molossid (from Volcan de Chinandega--J.
A. Allen, 1908:670) has been reported from Nicaragua. All of our
specimens are from the northern or northwestern part of the country.
Many were shot in early evening as they followed a straight, direct
flight pattern (presumably from day-roosts toward foraging or watering
areas); the series from Potosi was netted over a small stream as
described in the account o
