NO. 36. MEGADERMA LYRA.
_The Large-eared Vampire Bat_ (_Jerdon's No. 15_).

HABITAT.--India and Ceylon.

[Figure: _Megaderma lyra_.]

DESCRIPTION.--Above ashy blue, slaty or pale mouse colour; albescent
or yellowish ashy beneath; nasal appendage large, oblong, free at
the tip, reaching to the base of the ears with a fold down the centre;
tragus (_oreillon_) cordate, two-lobed, anterior long, narrow and
pointed, posterior lobe half the height and rounded; muzzle
truncated; under-lip cleft; wing membranes dark brown.

SIZE.--Head and body, 3 or 3-1/2 inches; wing extent, 14 to 19 inches.

Very abundant in old buildings. They are beyond doubt blood-suckers.
Blyth noticed one fly into his room one evening with a small
_vespertilio_, which it dropped on being chased. The smaller bat was
weak from loss of blood, and next morning (the Megaderm having been
caught), on both bats being put into the same cage, the little one
was again attacked and devoured; it was seized both times behind the
ear. McMaster writes that in Rangoon he had a tame canary killed by
a bat, and the bird's mate soon afterwards was destroyed in the same
way. The case was clearly proved.

Mr. Frith informed Mr. Blyth that these bats were in the habit of
resorting to the verandah of his house at Mymensing, and that every
morning the ground under them was strewed with the hind quarters of
frogs, and the wings of large grasshoppers and crickets. On one
occasion the remains of a small fish were observed; but frogs
appeared to be their chief diet--never toads; and of a quiet evening
these animals could be distinctly heard crunching the heads and
smaller bones of their victims.

NO. 37. MEGADERMA SPECTRUM.
_The Cashmere Vampire_ (_Jerdon's No. 16_).

HABITAT.--Cashmere.

DESCRIPTION.--Above slaty cinereous, whitish beneath; the vertical
nose-leaf of moderate size, oval; inner lobe of tragus ovate
(_Jerdon_).

SIZE.--Two and three-quarter inches.

Dobson makes this bat synonymous with the last.

NO. 38. MEGADERMA SPASMA.

HABITAT.--Tenasserim, Ceylon.

[Figure: _Megaderma spasma_.]

DESCRIPTION.--Muzzle, ear-conch, and tragus similar to those of _M.
lyra_; the posterior portion of the tragus, however, is longer and
more attenuated upwards, and more acutely pointed; the nose-leaf is
shorter, with convex sides; but the anterior concave disc is
considerably larger, and the base
