Natalus stramineus saturatus Dalquest and Hall, 1949

_Specimens._--_Granada_: 6 km S Nandaime, 5. _Zelaya_: S side Rio

Mico, El Recreo, 25 m, 2.

This funnel-eared species occupies an extensive geographic range

(northern Mexico to Brazil) but appears to be relatively rare in Middle

America to the south of Guatemala. Our specimens represent the first of

this species to be reported from Nicaragua.

Both specimens from El Recreo, adult males, were caught by hand at

night after they flew through an open door into a small room, possibly

seeking insects that were swarming around a light bulb. Those from near

Nandaime (three males, two females) were caught in a mist net set over

the mouth of a well in which they were roosting; the well was

approximately 2 m in diameter, and the water level was about 5 m below

the rim. The females were not reproductively active (6 August).

We have compared our Nicaraguan material with a number of Mexican

specimens, including the holotype of _N. s. saturatus_ and topotypes of

_N. s. mexicanus_. We concur with Goodwin (1959) that in Mexico there

are two rather distinct subspecies, between which a broad zone of

intergradation obtains. Our Nicaraguan specimens agree most closely

with _N. s. saturatus_, and, until additional comparative material is

available from Middle America, we tentatively refer them to that race.

Handley (1966b:770) and Starrett and Casebeer (1968:15), however,

regarded _mexicanus_ as the appropriate name for specimens from Panama

and Costa Rica.

Selected measurements of two males from El Recreo are: length of

forearm, 41.2, 39.0 mm; greatest length of skull, 17.1, 16.5 mm;

zygomatic breadth, 8.4, 8.5 mm; mastoid breadth, 7.7, 7.6 mm; breadth

of braincase, 8.2, 8.1 mm; interorbital constriction, 3.2, 3.2 mm;

length of maxillary toothrow, 7.3, 7.1 mm.
