UROCRYPTUS.— NYCTICEJUS.

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- 

 what less than the preceding ; and is found in numerous bands on the 

 copse which skirts the banks of the River Amazon.

SPECIFIC CHARACTERS. 



The Hair 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 three inches ; of 

 the tail not an inch ; 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 inches. 



GENUS XXII. UROCRYPTUS— CONCEALED-TAIL 

 BATS. 



Syn. Urocryptus, ( Chauve-souris a queue Cachee.) — Temm. Mon. II. 144. 



Although M. Temminck indicated the existence of this genus as far 

 back as the year 1838, with the promise he would immediately publish 

 the details concerning it, yet the work has hitherto been delayed. He 

 states that this 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 

 the dental apparatus, which corresponds to that of the Bats.

The Ears small. The Muzzle simple. 



The Chanfrin very broad. The Forehead narrow. The Occiput 

 elevated. 



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.*Rafinesque, 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 the 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, aDd 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.

SPECIFIC characters. 



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 short and obtuse. 



The 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 head is long; the ears wide apart; 

 the lips also are long, but 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.
