r evidently was
reproductively quiescent. Testes of adult males varied in length from 3
to 10 mm on the following dates (testicular lengths in parentheses): 25
February (10 mm); 21 March (8, 8 mm); 17 June (3, 4 mm); 13 July (6
mm); 27-28 July (4, 4 mm); 3 August (4 mm); 5 August (3 mm); 9 August
(4 mm).

We follow Starrett and Casebeer (1968:12) in the use of the specific
name _major_, rather than _caraccioli_ as suggested by Cabrera (1958),
Goodwin and Greenhall (1961), and Handley (1966b).

Vampyressa nymphaea Thomas, 1909

A pregnant female (crown-rump length of embryo 5 mm) was captured in a
mist net set in a small banana grove on the south side of the Rio Mico,
El Recreo, 25 m, in the Caribbean lowlands, on 27 February 1968. This
specimen provides the first record of the big yellow-eared bat from
Nicaragua. The species was recently reported for the first time from
Costa Rica (Gardner _et al._, 1970:721); it was characterized as
uncommon in Panama by Handley (1966b:767). The one Costa Rican locality
of record also is in the Caribbean versant.

Selected external and cranial measurements of our female are: total
length, 58 mm; length of hind foot, 11 mm; length of ear, 16 mm; length
of forearm, 36.2 mm; weight, 12.3 gms; greatest length of skull, 21.1
mm; condylobasal length, 18.4 mm; zygomatic breadth, 12.3 mm; mastoid
breadth, 10.5 mm; breadth across canines, 4.6 mm; breadth of braincase,
9.4 mm; length of maxillary toothrow, 7.2 mm; length of mandibular
c-m3, 7.8 mm.

The only previous record of occurrence for the small yellow-eared bat
from Nicaragua is based on an adult female from Hda. La Cumplida, 670
m, Matagalpa (Starrett and de la Torre, 1964:60).

Two individuals taken near Esquipulas in mid-March, a pregnant female
(crown-rump length of embryo 16 mm) and a male (testes 4 mm), were
captured in nets set across trails cut through secondary forest. The
wind was quite strong in this area at the time of our visit and only a
few other species of bats--_Glossophaga soricina_, _Artibeus
jamaicensis_, _A. toltecus_, _A. phaeotis_, _Uroderma bilobatum_,
_Sturnira lilium_, _Centurio senex_, and _Diphylla ecaudata_--were
taken in the same nets. The speci
