nside the cave. Therefore, the specimen in question may
be of Recent origin.

It is perhaps worthy of note that Lasiurus cinereus is primarily a
tree-dwelling bat, although a few Recent specimens have been reported
from caves (see Beer, 1954:116).

_Corynorhinus tetralophodon_ Handley

A single cranium of a _Corynorhinus_ LACM (CIT) 2989 was included in
the original materials sent to Kansas by Professor Stock. Subsequently,
this specimen was loaned to Charles O. Handley, Jr., who described it
as a new species, _C. tetralophodon_. The latter is said to differ from
all other plecotine bats by the retention of a well-developed fourth
commissure (ridge extending posteroexternally from metacone) on the M3
(Handley, 1955:48).
