; tragus broad and rounded above, partially
concealed by the large anti-tragus.

SIZE.--About the same as the last.

SUB-FAMILY VESPERTILIONIDAE.

These bats have simple nostrils, as in the frugivorous ones, with
no complications of foliated cutaneous appendages; the muzzle is
conical, moderately long, and clad with fur; the ears wide apart;
the inner margins springing from the sides, not the top of the head;
the tragi are large; eyes usually very small, and the tail, which
is long, is wholly included in the membrane.

Dentition (usually): Inc., 2--2/6; can., 1--1/1--1, premol.,
3--3/3--3; mol., 3--3/3--3. The upper incisors are small, and placed
in pairs near the canines, leaving a gap in the centre. The lower
ones sharp-edged and somewhat notched. At birth there are twenty-two
teeth, which are shed, and replaced by others, with sixteen
additional ones, the adult bat having thirty-eight teeth.

_GENUS PLECOTUS_.

Ears very large, united at the base; outer margin of the ear conch
terminating opposite the base of the tragus, the inner margin with
an abrupt rounded projection directed inwards above the base; tragus
very large, tapering upwards, with a lobe at the base of the outer
margin.

Dentition: Inc., 2--2/6; can., 1--1/1--1; premolars, 2--2/2--2;
molars, 3--3/3--3.

The English species _P. auritus_ is very common there, and also in
France; its ears are nearly as long as its body, yet, when reposing,
they are so folded as to be almost out of sight. The Indian species
is only a variety distinguishable by its yet longer ears ("and
comparative shortness of the thumbs"--_Dobson_).

NO. 77. PLECOTUS AURITUS _vel_ HOMOCHROUS.

HABITAT.--The Himalayas and the Khasia Hills.

[Figure: _Plecotus auritus_.]

DESCRIPTION.--Head slightly raised above the face-line; ears nearly
as long as the fore-arm, joined by a low band across the forehead
at the bases of their inner margins; wings from the base of the toes;
feet slender; tip of the tail free; fur silky, short, and of a uniform
dull brown.

SIZE.--Head and body, 1.7 inch; ears, 1.55 (ears of English type of
same size, 1.4 inch); tail, 1.7 inch. Jerdon gives larger results,
but I put more reliance on Dobson's figures.

_GENUS VESPERUGO_.

Bats with very broad and obtuse muzzles; the glandular prominences
much developed between the eyes and the nostrils; crown of the head
flat; but what distinguishes it from the following genus,
_Scotophilus_, is the
