14. Nyctinomus australis. 



Molossus australis, Gray, Mag. Zool. Bot. ii. p. 501 (1838). 



Ears large, but shorter than the head, their inner margins arising 

 close together on the muzzle from distinct points of origin, as in N. 

 africanus ; integument forming the ear-conch rather thin ; keel very 

 deep in lower third, but short and exceedingly thin, bent upwards 

 and backwards ; margin of the conch straight or slightly concave in 

 superior third ; antitragus very large, as high as long, posterior 

 margin straight, anterior slightly convex, narrowly rounded oif above ; 

 tragus short and broad as in N. cegyptiacus ; but its outer margin is 

 distinctly concave about the middle, and there is an obtuse projec- 

 tion at its base. Upper lip with short vertical wrinkles. The mouth 

 of a very large gular sac, larger than in any other known species of 

 this genus, extends across the throat from a point on each side near 

 the anterior termination of the antitragus, opening forwards as in 

 Taphozous. 



\Vings from the distal third of the tibia. Fur moderately long ; 

 above dark reddish-brown, beneath paler ; the base of the hairs on 

 both surfaces much lighter. On the dorsal surface the wings are 

 covered as far as a line drawn from the middle of the humerus to the 

 distal third of the femur, also the base of the interfemoral as far as 

 a line drawn between the knees ; beneath, a narrow band of fur 

 extends outwards behind the forearm, becoming wider in the angle 

 between the forearm and the fifth metacarpal bone, along which it 

 extends for half its length, and, passing over, covers the space be- 

 tween it and the upper third of the fourth metacarpal. 



Upper incisors rather long, separated by a narrow space in the 

 middle ; lower incisors 4, bifid : first upper premolar minute, in the 

 space between the canine and second premolar, drawn slightly in- 

 wards.
