Condega, 800 m, in Madriz, on 23 June 1964, provide the first record of
this small sac-winged species from Nicaragua. The bats were shot from
daytime roosts in small, well-lighted, cave-like spaces formed among
immense blocks of granite in a small patch of tropical deciduous forest
surrounded by extensive pine-oak woodland. None of the adult females
was reproductively active. _Glossophaga soricina_, _Diphylla ecaudata_,
and a large nursery colony of _Desmodus rotundus_ were found in
association with the _Peropteryx_. Measurements of our specimens agree
closely with those reported for material from El Salvador (Felten,
1955:284) and Costa Rica (Starrett and Casebeer, 1968:3-4).

This species has been reported previously from Nicaragua by several
authors. All our specimens were netted over small streams or shot as
they foraged; parts of scarabids and lepidopterans were found in the
mouths of several individuals shot at Finca Amayo. Twenty-six of 31
autopsied females taken in April were pregnant, each containing a
single embryo--average crown-rump length 16.7 (5-26) mm. Testes of 15
males collected in April had an average length of 4.6 (2-7) mm, those
of four taken in June, 5.2 (4-6) mm.

We follow Cabrera (1958:55), Husson (1962:63), and Handley (1966b:758)
in use of the subspecific name _labialis,_ the type locality of which
is the "Mosquito shore" of Nicaragua, rather than Peru as suggested by
Hershkovitz (1949:433-434).

This fish-eating species, first reported from Nicaragua by Davis _et
al._ (1964:376), apparently occurs throughout Middle America, although
known from the region by comparatively few records. We have 13
additional Nicaraguan specimens as listed above.
