bsided and remnants
of the old pelage (rich ochraceous orange) were confined to a narrow
strip at the lateral edges of the body.

We tentatively apply the subspecies name _fuscus_ to our Nicaraguan
bats on geographic grounds; one of us (Smith) currently is
investigating geographic variation in the genus _Pteronotus_.

Pteronotus suapurensis (J. A. Allen, 1904)

_Specimens._--_Chontales_: Cuapa, 1. _Matagalpa_: 3 mi E San Ramon,
24. _Zelaya_: Cara de Mono, 25 m, 4.

This relatively poorly known monotypic species occurs from southern
Veracruz to the Amazon Basin. It has been reported from several
localities in Central America including one in Nicaragua (Goodwin,
1942a:88). Three pregnant females from near San Ramon (9 May) carried
embryos that had crown-rump lengths of 27, 27, and 28 mm, and two
netted on 24 April at Cara de Mono each had an embryo that measured 22
mm. All of our specimens are in bright pelage that is fulvous red in
color.

Micronycteris megalotis mexicana Miller, 1898

_Specimens._--_Carazo_: 3 km N, 4 km W Diriamba, 600 m, 5. _Granada_:
Hda. Mecatepe [2 km N, 11.5 km E Nandaime], 5. _Managua:_ 5 mi NW
Managua, 1. _Matagalpa_: Rio Viejo, 7 mi WNW Dario, 4; 11 mi SE
Dario, 1. _Zelaya_: S end Isla del Maiz Grande, 9.

The individuals from Isla de Maiz Grande were shot on 30 June as they
flew from small caves and crevices in rocky outcrops on the south end
of the island. Of the three adult females obtained at that time, two
were lactating; each was accompanied by a young, the forearms of which
measured 19.7 (male) and 21.3 mm (female). Two adult males from Isla
del Maiz Grande had testes 2 mm in length.
