muzzle, projecting slightly by their inner margins in front, opening 

 STiblaterally, emarginate between, and closer together than in other 

 species of this genus (Plate XTV. fig. 3 a). Ears very rhomboidal 

 in outline ; the outer and upper angle, forming the tip, rounded ofi'; 

 the lower half of the outer margin slightly reflected backwards at 

 the edge ; emarginate opposite the base of the tragus, and termi- 

 nating in a distinct rounded lobe close to the angle of the mouth, 

 not hanging vertically downwards at its termination as in C. gouldii 

 (fig. 3) ; tragus expanded outwards above, reaching its greatest 

 width above the middle of the inner margin, the breadth of the 

 summit equal to the length of the inner margin, which is straight 

 or slightly concave. On the whole, the form of the tragus is very 

 similar to that of C. gouldii. 



Wings to the base of the toes ; postcalcaneal lobe rounded, well 

 developed, about the breadth of the foot from the tibia ; last rudi- 

 mentary joint of tail free. 



Above deep black, the tips with a slight brownish or greyish 

 tinge ; beneath similar, the tips ashy and generally of a lighter shade 

 on the pubes and along the sides of the body. 



Distribution of the fur and dentition quite similar to those in 

 Ch. gouldii.

The crown of the head is abruptly elevated above the face-line as 

 in Miniopterus, but to a much less extent ; muzzle short, very obtuse 

 in front, broad and flattened above ; nasal apertures wide apart in 

 front, separated by a slightly concave space, opening sublateraUy, 

 bounded laterally by the front margins of the labial glandular pro- 

 minences, which are separated from the nostrils above by a sulcus on 

 each side, as in the other species of this genus. Beneath, on each 

 side of the chin, below the under lip, a smooth broad rounded ele- 

 vation exists, separated from its fellow of the opposite side by the 

 small naked space on the lip in front of the lower incisors. These 

 elevated sides of the chin are covered with short hairs and enclose a
