The Nose prolonged, pointed, and somewhat pendant. 
The Wings projecting far before the head. 
Inhabits the Brazils. 
The information we possess of this species is very scanty. It is some- 
wliat less than the preceding ; and is found in numerous bands on the 
copse whicli skirts tlie banks of the River Amazon.

The Haib of a uniform deep brown colour, as are the membranes. 
The Snout prolonged, and somewhat turned up. 
The Alar Membranes ample ; the interfemoral long and truncated. 
The Tragus very short. The Spur very long. 
Inhabits Brazil. 
The length of the head and body of this Bat is nearly tliree inches ; of 
the tail not an incli ; the extreme breadth is eleven. The fur throughout 
is dense, soft, and long. Prince Maximilian found it among old ruined 
edifices.

The Fur reddish-brown. 
The Membranes dark brown, and very ample. 
The Muzzle somewhat pointed. The Tail short. The Foot 
small. 
The Spurs very long, so as almost to touch, making 
The Interfemoral pointed. 
Inhabits Brazil. 
The length of the head and body of this species is about two and a 
half inches, and its extreme breadth somewhat more than twelve. The 
ears are long, pointed, and distinctly rugous externally. Prince Maxi- 
milian observed this animal in the small river Joucou, near the Santo 
Spirito.

specific characters. 
The Face depressed. Forehead rounded. 
The Spurs about four lines long. 
A satisfactory account of this species has not hitherto, we believe, been 
published ; at least, we have not been able to find it in any work of Kuhl 
to which we could refer. The animal, however, is preserved in the Ley- 
den Museum, and is reported to have been received from Java. Mr 
Gray says that the wings are brown ; expanse, six indies.

Although M. Teinrainck indicated the existence of this genus as far 
back as the year 1838, with tlie promise he would immediately publish 
the details concerning it, yet the work has hitlierto been delayed. He 
states that tliis genus and the Emballonura form two small groups be- 
tween the Taphozous and the True-Bats. In both groups the interfe- 
moral is pierced by the tail as in Taphozous, but they differ from it in 
tlie dental apparatus, which corresponds to that of the Bats.

The Ears small. The Muzzle simple. 
The Chanfrin very broad. The Forehead narrow. The Occiput

The Interfemoral Membrane pierced by the tail, which is usually 
long. 
Inhabits all the Continents, except Europe. 
The Roquet-Dog Bats, with the ears of moderate size, and the 
simple muzzle of the Proper Bats, have only two incisors in the 
upper jaw. The known species are of South America, [as well as 
of the Old World.] 
This genus was instituted by M.vRafinesque, upon the examination of 
some of the numerous species of Bats which he discovered in the pro- 
vinces of Ohio, Indiana, and Illinois, in North .America ; and it is a mat- 
ter of regret that these have not subsequently been re-examined by any 
competent scientific Naturalist. The incisors always nearly approximate 
to tlie canines, and are invariably long, conical, and pointed like the eye- 
teeth. The intermaxillary bones are rudimentary, and firmly united to 
the maxillaries throughout their extent. The lower incisors are always 
more or less crowded. When the false molar is present, it is always ex- 
tremely small, not in the range with the other teeth, and placed behind 
the heel of the canine. The enlarged form of the chanfrin, and the ele- 
vated occipital bone, confer on this genus a strong resemblance to many 
dogs, more especially the Roquet-Dogs. Their mouth and muzzle are 
large, and their head appears so from the ears being so far apart : these 
appendages are not complicated, but always short and round ; their tra- 
gus, too, is short and obtuse. Their fur is generally short, and very 
smooth, and some species are partially naked, more especially on the ab- 
domen, croup, and thighs. 
The genus may be divided into two groups, those which belong to the 
Old World, and those found in the New. These latter have the fur 
usually longer, and the interfemoral membrane more or less clad with 
hair.

The Hair fawn brown above, and dark brown beneath. The Mem- 
branes black. 
The Ears are triangularly oval and short, being about one third the 
length of the head. The Tragus sliort and obtuse. 
Tlie two last joints of the tail extend beyond the membrane. 
Inhabits Senegal. 
This Bat is of large dimensions, extending, in extreme length, includ- 
ing the tail, measuring three inches, to more than seven ; the extreme ex- 
panse is about twenty inches. The liead is long ; the ears wide apart ; 
the lips also arc long, hut not warty, and the chanfrin projecting. 
It was Adanson who sent this animal from Senegal ; and it has long 
been preserved in the Paris Museum.
