DESCRIPTION (_apud_ Dobson).--"Gular sac absent in both male and
female; its usual position indicated in the male by a semi-circular
fold of skin and nakedness of the integument in this situation; in
other respects similar to _T. nudiventris_. The deposits of fat about
the tail very large."

SIZE.--Head and body about 3 inches; tail, 1-1/4.

_T. nudiventris_, above alluded to, is an inhabitant of Asia Minor,
Egypt, and Nubia; similar to the above, only that it has a small gular
sac in the male, of which a trace only exists in the female. Its most
striking peculiarity is the deposit of fat at the root of the tail,
which may possibly be for purposes of absorption during the dormant
winter season.

_GENUS NYCTINOMUS_.

"Ears broad, short, approximate or connate with the outer margin,
terminating in an erect lobe beyond the conch; tragus small,
concealed" (often very small and quadrate, but never reduced to a
mere point, as in _Molossus_--Dobson); "wings narrow, folded as in
_Taphozous_; intercrural membrane short, truncate; tall free at the
tip; feet short, with strong toes; muzzle thick; lips tumid, lax;
upper lip with coarse wrinkles."--_Jerdon_.

Dental formula: Inc., 2/6 or 2/4; can., 1--1/1--1; premol.,
2--2/2--2; mol., 3--3/3--3.

NO. 75. NYCTINOMUS PLICATUS.
_The Wrinkle-lipped Bat_ (_Jerdon's No. 34_).

HABITAT.--India generally.

DESCRIPTION.--Muzzle broad and thick; upper lip overhanging the
lower, marked by vertical wrinkles; ears large and quadrilateral;
outer margin ending in a decided anti-tragus; tail thick; the lower
part of the leg is free from the wing membrane, which however, is
connected with the ankle by a strong fibrous band; fur dense, smoky
or snuff brown above (or bluish black--_Dobson_); paler beneath.

SIZE.--Head and body about 2-1/10 inches; tail, 1-1/10. Jerdon gives
length, 4-1/4 to 4-1/10; expanse, 13-1/2; tail, 1-3/4.

This bat is common about Calcutta, frequenting ruins, dark places
and hollow trees. It is allied to _N. tenuis_ (_Horsfield_), and it
is mentioned as inhabiting hollow trees in such numbers as to attract
attention by the hissing noise from within, every available spot in
the interior being occupied. A synonym of the genus is _Dysopes_.

NO. 76. NYCTINOMUS TRAGATUS.

HABITAT.--India generally.

DESCRIPTION.--This differs from the last in having the wing membrane
from the ankles, and in the free portion of the tail being shorter;
ears united at the base
