small inner posterior basal lobe, and a well defined collar. 3folars, 

 above, first and second equal, having three pointed sharp ridges 

 externally, formed by two triangular groves in the crown of the 

 tooth, and two sharp similar ridges internally ; each with a strong 

 triangular sharp inner basal lobe ; third molar, a compressed 

 sharp ridge with a small tubercle on either side at the base. 

 Molars below ; first and second nearly equal, showing two 

 exterior triangular concical tubercles, the anterior one the larger, 

 and three inner smaller tubercles ; third smaller, with two outer 

 similar ridges and two inner tubercles. 



There is no sign of a gular pouch.* 



A few long hairs directed forwards on the side of the 

 face, a fringe of short hairs on the lips, nostrils on margin of 

 upper lip, terminal, simple ; the fur on the throat and chest long 

 and silky, a few black hairs at the base of the ears inside. The 

 ■wins membrane extends from the ankles. The whole of the 

 membrane, skin and fur of the upper surface jet black, silky ; the 

 whole of the under surface silky white. Sex, a male. 



Hab. holes and caverns in rocks, near Bulli, sea coast, East 

 coast of N. 8. Wales. 



This fine species was first found some twelve months ago, by my 

 friend Ralph Hargrave Esq., at Stan well, near Bulli. It is larger 

 than the majority of our bats, and may easily be distinguished by 

 the snow-white colour of the fur on the under side ; and the mem- 

 brane and whole of the fur on the upper side being black. It seems to 

 be allied to Taphozous affinis, of Dobsonf, from Labuan, but 

 differs in having no pouch, and in the shortness of its tail, also in 

 the colouring of the different parts. The tail is remarkably short 

 about half an inch within the outer margin of the caudal membrane, 

 which is three-sided {not pointed), the two lateral margins con- 

 nected with the ankles are thickened. 



* The skin is much mutilated, but I hare examined it carefully in water,
