their small size (Table 2).

Six of our specimens are females and each carried an embryo (range in
crown-rump length 20-28 mm). Three adult males had testes 5, 6, and 7
mm in length. External measurements (extremes in parentheses) of our
series are: total length, 55.9 (51-60) mm; length of hind foot, 10.7
(10-12) mm; length of ear, 14.8 (14-16) mm; weight of four males, 9.9
(8.8-11.5) gms; weight of six pregnant females, 14.9 (12.7-16.9) gms.

Artibeus toltecus toltecus (Saussure, 1860)

_Specimens._--_Matagalpa_: Santa Maria de Ostuma, 1250 m, 5; 2
km N, 6 km E Esquipulas, 960 m, 1.

This bat has been reported from Nicaragua previously by Andersen
(1908:300) and Davis (1969:28), based on a total of four specimens. We
netted this species at Santa Maria de Ostuma in patches of cloud forest
at a cafetal. The specimen from near Esquipulas was taken in a net
placed across a trail in second growth forest. Two females collected on
11 April and one taken on 30 June were pregnant (embryos 21, 26, and 12
mm, respectively, in crown-rump length). Testes of a male netted on 14
March were 7 mm in length, whereas those of two obtained on 11 April
measured 4 and 7 mm. Selected measurements of our six specimens are
given in Table 2.
