Ears oval-triangular, shorter than the head; tragus terminating in a round head: fur long, bright chestnut above, darker beneath : under surface of the flying membrane with a broad band of hair along the fore-arm.

V. Leisleri, Desm. Mammal, p. 138.


Length of the head and body two inches two lines; of the head seven lines and a half; of the tail one inch eight lines; of the ears five lines; of the tragus two lines and a half; breadth of the ears four lines ; of the tragus one line and a quarter ; length of the fore-arm one inch six lines and a half; of the thumb one line and three quarters: extent of wing eleven inches.


Muzzle rather more elongated than in the Noctule; nose depressed, naked, as is also the region of the eyes: ears oval-triangular, shorter than the head, broad, the outer basal margin advancing forwards to nearly the corners of the mouth ; tragus terminating in a round head, bulging out about the middle of the external margin, slightly bending inwards at the extremity, considered relatively, somewhat larger and longer than in the last species. Fur on the upper parts bright chestnut, this colour occupying the tips of the hairs, the roots of which are deep brown; under parts darker than the upper, the hair being grayish brown at the tips, dusky at bottom : Hying membranes dusky ; the portion contiguous to the body very hairy; a band of scattered hair also extends along and beneath the fore arm, about five lines in breadth : upper half of the in-terfemoral membrane both above and below likewise very hairy. Thumb short: bones of the arm and fore-arm much slenderer than in the Nodule.

The only indigenous specimen which I have seen of this species is in the British Museum. It is not known where it was taken. According to Desmarest it resides constantly in hollow trees in large companies, and is attached to the neighbourhood of stagnant waters.
