THE PROPER BATS.

would be general, wliercas the hair generally is black, and it is only the 
points that are white. Their habitat is far from being ascertained, though 
it is probably South America, as the individuals in the Leyden Museum 
were discovered in a collection which was made in that part of the world. 
The examination of those which have come to hand proves that they 
were young, and probably the adult will be of much larger dimensions. 
75. V. PARVULUS THE LITTLE BAT. 
M. Natterer, of Vienna, captured this Bat in the Brazils, and deposit- 
ed specimens in Austria and Holland. M. Temminck considers it as new. 
It is less than the Pijiislrelle of Europe. The ears are small, straight, 
pointed, with a very distinct lobe at the lower part ; the tragus too is 
straight, shaped like the willow-leaf, with an external leaf at its base ; the 
muzzle is very short and obtuse, and there is a very large wart on the 
lower lip : the interfemoral membrane is clad both above and below. The 
fur is bushy, but not very long ; the superior parts are of a dull black ; 
the sides of the neck, and lateral parts of the chest, are more dingy than 
the back ; the front of the neck, and the mesial line of the abdomen, 
and the sides, have the points of the hair brown ; an isabelle hue to- 
wards the limbs. The total length is 2J", the expanse 7". 
76. V. iENOBARBUS — THE RED-BEARDED BAT. 
The size of this animal is much less than the Pipistrelle of Europe, 
and the expanse, especiallj', is very limited. The muzzle is short ; the 
ears as broad as long, round at the point; the tragus is curved towards 
the head. The tail is very short, and its delicate point is free ; the base 
only of the upper surface of the interfemoral membrane is clad. The fur 
is long, and bi-coloured throughout. Above, it is reddish. brown, the 
base of the hair being black ; the forehead, checks, and chin, are red ; 
the sides of the neck reddish ; the pubic region pure white ; the abdomen 
whitish, the flanks light reddish, but in all these places the roots of the 
hair are black. The total length is '2" 3"', the breadth 6|-", (French.) 
The habitat of this species is not ascertained, being grounded on a single 
female specimen which was sent from South America. — (Fig. in Temm. 
Mon. II. pi. 58, iig. 4) 
77. V. ARSINOE.— ARSINOE’S BAT. 
M. Temminck regards this as a new species, an old female having 
reached Leyden from Surinam. It has the same dimensions and forms 
as the Whiskered Bat of Europe. (See No. 8.) Its head is short and 
depressed; its muzzle obtuse ; its ears conical, with a round point, and 
no scooping out ; the tragus straight, and lance-shaped. There are six 
molar teeth above and below, two of which, in each jaw, are false. The 
fur is very short, smooth, and spare, and the membranes are totally naked. 
The upper parts of the body are perfectly black and shining ; the lower 
of a blackish-brown, the tips being fawn-coloured. The robe on the 
flanks, and round the coccyx, are larger than on the chest, of a blackish 
brown, tipt with white; this marking forms, round the body, a kind of 
whitish grey. The total length is upwards of 2|", the expanse more 
than 8". 
78. V. POLYTHRIX.— THE POLYTHRIX BAT. 
This, and the preceding species, were transmitted by M. Augttste St 
Hilaire from the Brazils, and were described by his brother, M. Isidore, 
in the Ann. ties Sden. Nat. t. 3. They are unaccompanied, however, 
with figures, which is a great deficiency, so much so, as to leave some 
doubt as to their being distinct from those described by the Prince de 
Wied. However, they probably are. The size of this one is somewhat 
greater than that of the Pipistrelle. Its ears are small, larger than they 
ate broad, and scooped out at their external margin ; the body is nearly 
as long as the arm and fore-arm ; the tail as long as the fore-arm only. 
The interfemoral membrane is sparingly covered on its tipper face with 
hair; the face is much clad, being covered with very long hair; and only 
the end of the snout is left naked. The superabundance of fur gives it 
a rem.arkable and hideous appearance. The fur is soft, abundant, and 
substantial ; above, it is of a very deep marone colour, and below, a 
marone,, slightly verging to grey. The total length is 3^", and width 9", 
(French.) There is a specimen in the Paris Museum. 
79. V. LEVIS.— THE SWIFT BAT. 
This second species, described by M. Isidore GeofFroy, from the Brazils, 
>s smaller than tlie Pipislrelle of Europe, but is not less remarkable for 
the large development of .all its membranes. Its ears are nearly twice the 
size of those of the preceding species, and its tragus is prolonged in near, 
ly the same proportions, at the same lime, resembling them in shape. 
The tail is as long as the body, and the interfemoral membrane is greatly 
developed, almost equalling the length of the fore-arm. The face is sen- 
sibly less covered with hair than the Polythrix, and the interfemoral mem- 
brane is scarcely at all clad. The colours are nearly the same as the 
preceding. The total length is 2" 9'", the expanse 9". 
80. V. CHILOENSIS.— THE CHILOE BAT. 
This species was discovered by Mr Darwin, in the recent expedition 
of the Beagle, and has been described by Mr Waterhouse, in the “Zoo- 
logy of that voyage.” The colours and size of this species likewise 
resemble the Pipistrelle; whilst, at the same time, the wings are broader, 
the fore-arm, leg, and tail, are longer, and the tragus is also longer and 
straighter. The snout is obtuse, and supplied with numerous small 
bristles. The forehead is concavej the ears narrow and pointed, mar- 
ginated externally, and supplied with four transversal folds ; the tragus 
is long, filiform, pointed, and notched externally. A small protuberance 
is placed on the chin, from which proceed a few radiating hairs ; the tail 
is free at its point. The fur is of medium length, and of a beautiful 
uniform brown colour ; it extends to the base of the interfemoral, both 
above and below ; the rest of this membrane is naked and black, as are 
also the wings. The total length is 2" IJ'", the expanse is 8" 3'". This 
species was captured in the island Chiloe. — (Fig. in Zool. Voy. of the 
Beagle, pi. 3.) 
These eighty species, which we have now discussed as amply as our 
limits admit, include the whole number of those which M. Temminck, in 
his late Monograph, considers as established on sufficient and satisfactory 
grounds. To these he adds a short notice of many other species, of which 
the original notices have been more superficial, and somewhat incomplete; 
and as this information may be useful, under certain circumstances, to 
many inquirers, we shall here give an abridgment of his valuable remarks. 
To these, still followdng his guidance, we shall subjoin an account of ten 
species, of which there are specimens in the Paris Museum, and which 
were recently described by the late M. F. Cuvier, in the first vol. of the 
Nouvettes Annales du Mas. d'llist. Nat. And this accomplished, we 
believe we have omitted nothing whereby we may bring our account of 
this genus, as of those which have gone before, up to the level of the 
most recent intelligence which has been accumulated upon this very ex- 
tensive order. 
DOUBTFUL SPECIES. 
{European.') 
We adduce first the five European species which M. Brehm ofReuthen- 
dorf pretends (we use M. Temminck’s expression) to have discovered in 
his immediate neighbourhood. He describes them in his Ornis, 3d No., 
in these terms. The measurements are upon the scale of the Rheinland 
foot : — 
1. Vespertilio Sobmdrtnos The ears are much shorter than the 
head; the upper canine has no conspicuous edge behind, so that the first 
false molar is isolated, the second false is most conspicuous ; the two false 
molars are tolerably long and pointed. The expanse is from seventeen to 
eighteen inches. The upper parts of the body are brownish, the lower 
light grey, passing into white ; the muzzle dark grey. It delights in the 
hollows of fruit trees. This animal, M. Temminck says, may be a va- 
riety of the Murinus. 
2. V. WiEDii. — Ears very small ; the free part of the tail 2J'" long; 
breadth of the wings medium size ; the fur long and silky; expanse from 
15^" to 16". The upper parts of the body of a deep brownish-grey ; 
the lower, light grey ; the muzzle greyish-black ; the membranes above 
blackish-grey ; beneath, greyish -black. M. Brehm says, that this species 
is very rare in his locality. It is not much smaller than the Myotis, but 
is distinguished from it by its small cars, its narrower wings — by its long 
fur, and peculiar marking. 
3. V. Okf.kii Ears small ; teeth large ; wings of medium size : tip of 
the tail 3"' free ; fur of medium length, and soft ; above, brownish-black, 
beneath, schiste colour. Expanse from 14J" to 15". 'This is stated to 
be somewhat less than the preceding ; the free tip of the tail is longer, 
and the marking different. M. Brehm says it is rare. 
4. V. Februcin-eos The ears short, and roundly oval ; fur short, rust 
coloured; the wings very narrow ; expanse from 15" to 15^". This ap- 
pears to be only the Noctula, with a slight variation in the colouring. 
5. V. ScuiNzii The ears are 6"' long, and 2'" shorter than the 
head ; the tragus is long, and lance-shaped ; tip of the tail free, only a 
; wings broad ; so long and soft, that the very short muzzle is en- 
tirely hid ; the expanse from 9" to 10"; above, it is brownish-black.
