This handsome _Myotis_ has been reported previously from Nicaragua only
from the Caribbean lowlands--from the Escondido and Prinzapolka rivers
(Miller and Allen, 1928:203). We netted two specimens, both males, at
Santa Rosa, 17 km N and 15 km E Boaco, 300 m, Boaco, in central
Nicaragua on 13 July and 9 August 1967, under the same conditions
described in the account of _Myotis elegans_. Testes of our specimens
were 7 and 6 mm, respectively, in length. External and cranial
measurements are as follows: total length, 84, 83 mm; length of tail,
31, 33 mm; length of hind foot, 9, 9 mm; length of ear, 15, 15 mm;
length of forearm, 32.9, 35.1 mm; weight, 6.4, 6.2 gms; greatest length
of skull, 13.9, 14.4 mm; zygomatic breadth, 8.9, 9.0 mm; postorbital
breadth, 3.8, 3.9 mm; breadth of braincase, 7.2, 7.3 mm; mastoid
breadth, 7.4, 7.6 mm; breadth across upper molars, 5.6, 5.5 mm; length
of maxillary toothrow, 5.3, 5.3 mm.
