There are several species. 



T. Mauritianiu. Fur, chestnut above, ruddy below. Earlet termi- 

 nated by a sinuous border. Locality, Mauritius. 



'J'tiph'jzoit* Mauritianus, and profile of the same. 



Mormopi, Leach. Four upper unequal incisors, of which the inter- 

 mediate ones are widely notched, and four below which are equal and 

 trifid ; two canines in each jaw, the upper ones twice the length of 

 those below, almost compressed and canaliculated before ; five molars 

 above and six below on each side. A single nasal leaf united to the 

 ears, which are very complicated. 



M. Blainrillii, the only species ; and it is remarkable for the 

 extreme elevation of its front ; the excavation of its chanfrein ; the 

 lobated crenellated form of its upper lip, and the division of the 

 lower one into three membranous lobes ; the existence on the tongue 

 of papilla?, of which the anterior are bifid and the posterior multifid ; 

 the folding of the nasal leaf, and the division of the upper border of 

 its ears into two lobes. Locality, Jamaica. 



Nyctophtiut, Leach. Two upper, elongated, conical, pointed 

 incisors ; six lower ones, equal and trifid, with rounded lobes ; two 

 canines above and two below, the lower ones having a small point at 

 the back part of their base. Four molars on each side of the jawf, 

 with crowns furnished with pointed tubercles. Two nasal leaves, of 

 which the posterior is the largest. Tail projecting a little beyond the 

 interfemoral membrane. 



N. Geoffroyi, the only species known. Fur, yellowish above. Belly, 

 breast, and throat dirty white. Ears large. Membranes brownish - 

 black. 



2. Anutiofi/xiri, Spix. 



Bats without any nasal appendage. 



3. Sub-Family, VctpertUionina. 



Molar teeth with pointed tubercles. Wings wide and extended 

 A single phalanx to the forefinger (index). Head elongated. Th 

 lips Kiinple. Tongue short. Tail long. 



Vetptrtilio, Linn., Geoff. Upper incisors four, sometimes two. 

 Lower incisors six. Muzzle very simple. Ears separated, but some- 

 times united at their base. Earlet internal. Tail long, entirely 

 enveloped in the interfemoral membrane. Cheek pouches.

Lesson observes, that many Vaperlilione* have but two incisors. 

 The species of the genus are many in number, and their geographical 

 distribution is very wide. 



e. European Species. 



V. murintu, Linnaeus. This is the Flitter-Mouse, Flutter-Mouse, 

 and Rear-Mouse, of the English* ; La Chauve-Souris of Buffon, 

 ami, according to Pennant, the Ystlum of the Welsh ; the Nattola, 

 Notula, Sporteglione, Vispistrello, and Vilpistrello, of the Italians ; 

 Murciegalo and Morciegalo of the Spaniards ; Morcego of the Portu- 

 guese ; Speckmaus and Fledermaus of the Germans ; Vledermuys of 

 the Dutch ; Laderlap and Fladermus of the Swedes ; and Flagermaus 

 and Aftenbakke of the Danes. 



The ears are oval, of the length of the head ; the earlets falciform. 

 The fur of the adults is ruddy-brown above, whitish-gray below; 

 that of young individuals is gray-ash. 



This species is common in Europe. It has been supposed to exist 

 in Asia, and even in Australia. Its haunts are caves, ruined build- 

 ings, church-towers, the roofs of houses or churches, and hollow trees, 

 where it hybernates during the whole winter, snugly wrapped up in 

 the wing membranes, and suspended by the hind feet. We have 

 given the skeleton of this species, and below will be found a head and 

 skull of V. Pipistrdlus, another European species.

ft. African Species. 



V. nigrita. Adanson discovered this species at Senegal. The ears 

 are oval, triangular, very short, one-third of the length of the head. 

 Earlet long, aud terminating in a point. Fur yellowish-brown above, 

 and yellowish-ash below. 



7. Asiatic Species. 



V. pictus. The ears are shorter than the head, oval, wider than 

 they are high. Earlet oval-shaped. The fur is reddish, passing into 

 bright yellow upon the back, and of a tarnished yellow on the belly. 

 Citron-coloured rays mark the course of the fingers in the wings, 

 which are chestnut-brown. Locality, Ceylon. 



S. American Species. 



V. Nam. This species, remarkable for the length of its nose, was 

 first described by the Prince de Neuwied. The nasal organ is elon- 

 gated in a straight line above the upper jaw, almost like a proboscis. 

 The ears are small, and very much pointed. The fur is grayish-brown 

 above and yellowish-gray below. Locality, Brazil, in trees. 



Plecotut, Geoff. This genus in many of its characters agrees with 

 Veipertilio, but the ears are very much developed, being larger than 

 the head.

There are several species, and the form occurs in all the four quarters 

 of the globe. 



P. Ttmaritnrii. This species was discovered by PiSron and Lesueur 

 in the island of Timor, one of the Moluccas. The ears are ample, 

 united at their base by a small membrane. The fur is blackish-brown 

 above, and ash-brown below.

The genera Atalapka, Ilypexodun, and Nyctiocus of Rafinesque, are 

 considered doubtful by Lesson and others. 



Myopterii, Geoff. The chanfrein is united and simple. The ears 

 are large, insulated, and lateral, with an internal earlet. Tail long, 

 half enveloped in the interfemoral membrane. Muzzle short and large.

M. Daubenlonii, Geoff. ; Le Rat Volant (Flying Rat) of Daubenton. 

 The locality of this species, is unknown. The upper part of the head 

 and body is brown ; beneath, the colour is dirty white, with a slight 

 tinge of yellow. 



4. Sub-Family, Noctilionina. 



Molars tubercular. Wings long and straight. Two phalanges to 

 the forefinger (index). Head short and obtuse. Lips very large.
