l. This
situation led to formation of small "rooms" or "cubicles" under some
shorter trees; the bats were shot as they hung from small branches
under one such tree, which was in fruit. All of our other specimens
were captured in mist nets.

Pregnant females were taken on the following dates (crown-rump length
of embryo in parentheses): 25 February (12 mm), 2 March (17 mm), 15
March (14 mm); a nonpregnant female also was taken on 15 March. Five
males captured at San Antonio on 9 and 10 March had an average
testicular length of 5.6 (5-6) mm. A male taken in July had testes 4 mm
in length, whereas those of one obtained on 14 March were 5 mm long.

Selected measurements (average, with extremes in parentheses) of 11
adults (seven males and four females) are as follows: length of
forearm, 42.5 (41.5-43.7) mm; condylobasal length (10 specimens only),
14.8 (14.5-15.0) mm; zygomatic breadth, 14.8 (14.4-15.1) mm;
interorbital breadth, 5.0 (4.7-5.2) mm; breadth across upper molars,
10.6 (10.5-11.0) mm; length of maxillary toothrow, 5.0 (4.8-5.3) mm.
These measurements generally agree with those given by Paradiso
(1967:600) for 20 individuals from Panama. Females in our series
average slightly larger than do males in external and cranial
measurements. Six males weighed an average of 22.9 (20.7-25.1) gms; one
nonpregnant female weighed 17.1 gms.

Our specimens constitute the first report of this species from
Nicaragua. We follow Burt and Stirton (1961:37) in regarding _D.
ecaudata_ as monotypic.

Specimens from Los Cocos (three males and two females) were captured in
a mist net stretched across a large, quiet pool in a small stream. The
banks supported well-developed gallery forest, the understory of which
had been cleared for human habitation; grassland (grazed) and small
stands of secondary forest obtained beyond the riparian habitat.
Domestic ducks, a possible source of food, were observed sleeping along
the bank of this stream and on top of large boulders situated in the
stream. Males from this locality taken on 20 February, 4 April, and 18
July had testicular lengths of 5, 6, and 6.5 mm, respectively. Two
adult females collected there on 4 April were reproductively inactive.
An adult male (testes 6 mm) from near Condega was c
