(embryo 14 mm in crown-rump length), and
a hairless juvenile were shot, on 16 February 1964, from a small colony
in an attic of a large house southwest of Managua; _Glossophaga
soricina_ also was taken in this attic. The testes of an adult male
captured in June were 6 mm in length; those of four taken in July were
5, 5, 6, and 7 mm, and one obtained in August had testes that measured
3 mm.

Selected measurements of _M. s. sinaloae_ from El Recreo are given
in Table 4.

CHECKLIST OF NICARAGUAN BATS

Following is a checklist of the 68 species of bats thus far reported
from Nicaragua. Citations are given only to publications that are
primary sources of information on Nicaraguan specimens. In some
instances, specimens were reported in the literature under a name
different than the one here employed; we have mentioned earlier-used
names where it seemed appropriate to do so. Taxa preceded by an
asterisk are included in the present paper.
