THE ROUSSETTE BATS. 
9 
SPECIFIC CHAKACTERS. 
The Hair, on tlie head, pure white and brown ; on the neck, pale 
yellow ; on the shoulders, white ; and on the back, grey. 
The Membranes brown above, white beneath. The Interfemoral 
hid by the fur. 
Inhabits Island of Ternate. 
The Masked Roussette is of the same dimensions as the Grey. The 
ears are of medium length, somewhat rounded at the point ; the interfe- 
moral membranes are rudimentary ; the upper portion being quite hid by 
the fur ; all the membranes are brown above and whitish beneath. The 
upper incisors are well arranged, and in pairs ; the lower are separate, 
very slender, short, and obtuse ; there is a small anormal tooth in both 
jaws, the upper scarcely visible. The head of this species is strikingly 
marked with pure wliite and brown. Pure white covers the whole chan- 
frin, extends beyond the eye, and forms a spot behind it; the cheeks, 
margin of the lips and chin, are of the same colour ; a broad brown zone 
covers the throat ; the extremities of this zone surround the cheeks and 
extend to the nostrils. The crown, occiput, neck, and cheek, are of a 
pale yellow hue ; the shoulders and hairs of the arm are white, those 
of the back are grey, mixed with brown ; the chest, abdomen, and 
sides, have downy hair, brown at their base, and of an isabelle hue at the 
point. 
We owe the discovery of this beautiful species to Professor Rein- 
wardt, who described it in his Voyages aux Moluques. Its habits have 
not been observed.

SPECIFIC CHARACTERS. 
The Hair, on the chest and sides, light red ; on the abdomen, white ; 
a white tuft on each side of the neck, in the male only. 
The Lips greatly elongated in the male only. 
The Membranes brown. The Interfemoral rudimentary. The 
Alar commencing from the sides. The Ears very long and pointed. 
Inhabits Abyssinia. 
This beautiful Roussette, the male of which is remarkable for the ex- 
treme length of its hunch of oily hair, and the elongation of the two lips, 
is of the size of the Common Bat of English writers, K. Murinus. The 
muzzle is long; the incisors slender and in contact; a narrow membrane- 
ous appendix supplies the place of the interfemoral, which is throughout 
hid, and nearly clad by the fur ; the alar membrane proceeds directly from 
the sides ; the ears are long and pointed. There is a downy fur over the 
whole body, particularly on the back. The lips of the male project se- 
veral lines beyond the teeth, and as completely hide the gape of the 
mouth as in some large mastiffs, producing a singular physiognomy. The 
downy fur clothes all the humeral region, and the margin of the alar mem- 
brane adhering to the sides ; this, and that of the head, short, and not 
very abundant, is of a reddish isabelle hue, redder upon the back and 
crupper; the root of the ears, and their posterior margins, are covered with 
white hairs. From each side of the neck, of a reddish-brown colour, 
there arises a large pure white tuft of long hair; these large tufts, proba- 
bly covering as usual an unctuous apparatus, form two bunches, the 
hairs of which diverge as from a common centre. The chest, humeral 
region, sides, and coccygeal region, are of a light red ; the middle of the 
abdomen, where the hair is sliort and smooth, is of a dull white. All 
the membranes have the colour of a decayed leaf. 
The female is destitute of the cervical tuft, and labial peculiarity, but is 
nearly the same in regard to the markings. 
M. Botta presented to the Paris Museum two individuals of this new 
and beautiful species, discovered in his Abyssinian travels. The Leyden 
specimens were derived, one, without label, from London, and the other 
from M. Botta’s collection. 
(B.) Tailed Roussettes. (Roussettes avec 
ONE PETITE Queue.) 
M. Geoffrey was the first to describe the species of this subdi- 
vision. One of them (Pteropus JEgyptiacus) is found in Egypt in 
the cavities of the Pyramids, and another, with a tail not quite so 
long, and engaged to about the extent of a half in the membrane, 
(Pier, amplexdcaudatus,) comes from the Indian Archipelago. 
The section of the Tailed Roussettes is distinguished from the previous 
one by other characteristics than that expressed by their name ; for in them 
we find that the one half of the thumb is engaged in the alar membrane, 
and the maramse are placed higher up than the insertion of the arms ; 
while in the Tailless Roussettes, the whole of the thumb is free, and the 
mammoe are placed underneath the insertion of the humerus. All the 
species comprehended in this section are likewise small, or of medium 
size. M. Isidore Geoffroy informs us that he has examined the 
crania of the majority of them, and found some interesting characters 
which seem to be common to them all. In the species without a tail, 
the cerebral cavity is separated from the face by a considerable con- 
traction, corresponding in situation to tile posterior part of the orbit, 
whilst in those which have this appendage, there is no appearance of the 
contraction, as M. Geoffroy had previously remarked in the Pteropus 
marginatus. In these last, moreover, the cranium is somewhat more de- 
veloped, and the muzzle is not so slender. The dental system presents 
no particular character. The small false molar is usually found in the 
upper jaw, but very insignificant and almost useless, whilst it is often quite 
wanting in other species. These distinctions are more conspicuous in the 
smaller species than in the larger.

SPECIFIC characters. 
The Hair dull yellow above, greyish beneath ; a demi-collar of golden- 
red hairs on the sides and front of the neck in the males only. 
The Tail very short. 
Inhabits Senoaar and Senegal. 
For a long time this Bat was thought to be an inhabitant of the island 
of Timor, and it is still generally described as derived from that locality. 
There would appear, however, to be a mistake in this ; and its resi- 
dence is now ascertained to be Africa, in the neighbourhood of Sennaar 
and Senegal. 
Though the total length is about eight inches, that of the tail does not 
extend beyond two lines. In the adull male the fur is smooth, very short, 
and thin. The region of the sides and front of the neck is adorned with 
a demi-collar of golden-red hairs, which are diverging and unctuous, and 
confined to the males. In the fem.ile these p<arts are of a dull yellow 
colour, more or less clouded with light brown. The rest of the fur 
is the same in both sexes. Above it is yellowish, or of a dull white, 
the points of the hairs being brown or ash-coloured ; yellow prevails 
about the ears ; the middle part of the chest and of the belly is grey, 
clouded with brown; the remainder of the inferior parts, and the under 
parts of the legs and wings, are of a dull pale yellow.

specific characters. ' 
The Hair short and woolly, dull grey, deeper above. The Membranes 
brownish-grey. The Interfemoral broad. The Tail very short, one 
half surrounded by the membrane. 
Inhabits Northern Africa and Senegal. 
M. Tcmminck, as appears in the synonyma, has proposed a name for 
this species, different from that originally bestowed by M. Geoffroy, its 
first describer, at the same time paying him a well-merited compliment. 
The motive which influenced him was, that this Roussette was not confined 
to Egypt, but extended widely tbrouglioiit Alrica. Now, though this con- 
sideration, had it been known at tlie time, might have induced M. Geoffroy 
to avoid the appellation, yet, having been once fairly affixed, it should be 
preserved. Tlie reasons "for this are numerous and urgent, and quite suf- 
ficient, we apprehend, to vindicate us for not following even the high au-
