154 CLASS MAMMALIA. 



Its epithet, pictus, is given from the yellow streaks which 

 proceed from the carpus, and extend over the fingers. Its 

 head is large, the muzzle slender. The forehead is arched, 

 and the front of the cranium considerably incurvated; but 

 this is not very visible in the fresh state, as this part is 

 covered by long hairs, in which the ears are also partly 

 concealed. 



These, though oval, have a small point above. The 

 auricula is subulated, very narrow and long ; the fur is of 

 a very beautiful colour, being of a most brilliant golden- 

 red. The membrane of the wings is of a fawn-coloured 

 brown, and is radiated with yellowish streaks the whole 

 length of the fingers. 



The rough-tailed bat {vesp. lasiurus) inhabits Cayenne. 

 Schreiber and Pennant have given a tolerable description of 

 it. It is about the size of the emarginatus. Its ears are oval, 

 shorter than the head. The auricula narrow, and shaped like 

 ademi-heart ; the fur varied with yellowish and red ; radii 

 of a grayish-brown, proceed from the carpus, and extend 

 over the fingers. The hair above is yellow for almost its 

 whole length, and cinnamon-colour at the point. The belly 

 is yellowish. 



The Timor bat ( vespertiiio timorensis) is owing to the la- 

 bours and researches of M. M. Peron and Lesueur. The 

 ears are large, of the length of the head, and joined together 

 by a small membrane ; the auricula like a demi-heart. It is 

 brownish-black, and ashy in the under parts. The fur is 

 long, soft, and thick. 



The Bourbon bat {vespertiiio Borbonicus,) comes from the 

 island of Bourbon. It may thus be characterized : Ears tri- 

 angular oval, half as short as the head; auricula long, formed 

 like a demi-heart ; fur red above, and white below. Its head 

 is short and large ; muzzle inflated, and nose projecting. 



The Senegal bat of Pennant (vespertiiio nigritd) was called, 

 by Daubenton, the flying marmotte. Seba was the first who
