Of this species, onl}^ three specimens were obtained — a male and two 
females — all from San Julian. The male was cut down with a pole 
as it flew about the hut at dusk; a female was secured in the same 
manner a few days later, and the third was shot in a small cave, where it 
was in company with J^erojjfcJ'i/,r lajjjder/' iind Gloampluuja longlr<isf)'h. 
This species differs greatly in general appearance from the other two 
species of sac- winged bats; It lacks the pompadour bang, its ears are 
very ditferently shaped and proportioned, the w^ng sacs are difl'erently 
located, are operated l)y a larger muscle, are larger, and are very 
difterent on the interior. Both sexes have the sacs, but those of the 
male are much the larger. When opened, the interior is seen to be 
coarsel}^ rugose and whitish in color. The odor emitted is not very 
decided. 
The two whitish lines on the back are not parallel l>ut wavy, making a 
double lyre-shaped pattern as they exteild out upon the interfemoral 
mem))rane. 
Both females contained f(jetuses ready for exclusion.

33. LASIURUS BLOSSEVILLEI (Ferussac). 
SOUTH AMERICAN RED BAT. 
One specimen preserved in alcohol, a nearly adult male. It was 
brought in by a small boy at Macuto. The specimen, although present- 
ing some diflerences from topotypes of L. hlo-sseviUel from Paraguay, 
seems not to be separal)le from it, as the differences are slight and 
may be due to age. The Venezuelan bat is in every way a slightly 
smaller animal. The ear is smaller than that of Paraguayan s})ecimens, 
with smaller tragus, which is straighter and less convex anteriorly. 
The skull is smaller, with a rather relativel}' shorter facial portion. 
The palate is narrower, and also the notch between the incisors in 
front. Compared with the Mexican red l)at, it differs in being some- 
what smaller, Avhich may be due to its immaturity, and in having a 
slightly narrower ear, a noticeably smaller skull, relatively smaller
