p. 133, note 1.) The wliole length 3", one half being allowed for the 
tail ; the ears are longer than the head, and have a tragus ; the fur, dark 
grey above, is blueish-grcy beneath; the alar membranes are of a deep 
blueish-grey ; the toes are black. 
24. V. Mei,4Notis Rafin. Total length d j", tail occupying one half, 
the expanse 11^"; the tragus roundish ; the fur blackish above, whitish 
beneath ; the membranes dark grey ; the toes black. 
^25. V. Calcabatus Rafin. Total length 4", expanse 12"; it has 
a kind of spur on the inner side of the first phalanx ; the fur is blackish- 
brown above, and deep fawn-colour beneath. The wings are block ; the 
toes rose-coloured ; the feet are black. 
26. V. Monachus Rafin. The size of the preceding ; the tail equal 
to a third of the length, clad above, and wholly enveloped in the mem- 
brane : the ears are small, and hid under the hair, which is very long ; 
the fur above is deep reddish-fawn, and beneath fawn ; the feet are 
black ; the membranes dark grey, and the toes and nose rose-coloured. 
This is probably the Rcd~tned Bal already described, (No. 67.) 
27. V. Phaiops — R afin. Total length 4|", expanse 13", that of the 
tail 2" S'"; the external pair of upper incisors are larger "than the interior, 
and bi-lobed ; the fur is dull ba 3 ’-brown above, and paler beneath ; the 
face, ears, and alar membranes, are blackish. This seems the identical 
animal already described, (No. 62.) 
28. V. Mf.galotis — R afin. Total length 4", expanse 12"; tail 
somewhat less than 2". The fur is of a deep grey colour above, and of 
a pale grey beneath ; the ears, very large and double, are provided with 
a tragus as long as themselves. This is probably our Lan^-eared Bat 
already described, (No. 5.) also found in North America. 
SouTn America will probably yet supply many new species of Bats. 
M. D’Orbigny has indicated one, which is a Rkd Bat, in his beautiful 
work. Voyage dam VAmer, Merid. (pi. II. fig. 5.) As the descriptive 
letter-press has not yet been published, we of course cannot more par- 
ticularly describe it,

The Craniu.m rises nearly at a right angle from tlie face. 
The Upper Jaw is exceedingly depressed. The face is flat-nosed, and 
bristled with hairs. 
The Nail only of the thumb projects from the membranes. 
This Genus, established by M. Fr. Cuvier, and subsequently adopted 
by others, is based upon a single individual Bat which the French Na- 
turalists received from M. Leschenault, who captured it in his first jour- 
ney in America. There is no'difference, as will be perceived, in the num- 
ber of teeth, from what is found in many of the Genus Vesportilio ; their 
form, however, materially differs. The upper incisors are of the same 
size, and are pointed, and are not in contact with the canines. The 
lower incisors, again, are placed regularly upon the arc of a circle, but in 
pairs, trident-like, at three different parts of it. The upper canines are 
much stronger than the lower, tricuspid, one point anterior, the other 
posterior, and the central one by much the largest, and conical. The 
lower ones have the same shape ; and the false molars appear much more 
associated with them than with the true molars, on which we have no re- 
mark to make. hi. Cuvier conferred the name Fury upon this genus, on 
account of its singular appearance. It is very small, flat-nosed, and 
boarded ; the frontal and parietal bones rise almost at a tight angle from 
the face, and the other parts of the cranium follow in their train. The 
zygomatic arch is not horizontal, but rises high in projecting backwards ; 
the height of the upper jaw is nothing almost when compared with the 
Proper Bats, and the ascending branch of the lower jaw is very great. 
The organs of motion present nothing particular, with the exception re- 
garding the thumb already specified.

SPECIFIC characters. 
The Muzzle very flat, and studded with hairs. The Ears large, aaJ 
as broad as long. The Fur of a uniform black colour. 
I.VHABiTS South America. 
The eyes of this Bat are very prominent, and remarkable for a size 
which is not often witnessed in this order. The nostrils are terminal, 
and are separated from each other only by a margin which surrounds 
them, and which forms a furrow at their upper part. The lips are entire, 
but, along the upper, there are four or five warts, and, upon the lower, 
eight similar ones, which are the more conspicuous, as they are white, 
and situated amidst the black hair. The ears are large, nearly as broad 
as long, simple in structure, and provided with a tragus of a particular 
structure, having three points, which are arranged in the form of a cross. 
The fur is soft and thick, except at the muzzle, where it is longer, stiffer, 
and more shaggy than in the other parts of the body. The colour is a 
beautiful uniform black. The total length is only an inch and a half; 
the expanse six inches. The individual possessed by M. Cuvier was a 
male, which was discovered at Mona, by M. Leschenault, during his first 
journey in America.
