longer, first lower premolar close to canine, other ones 

 distant, second lower premolar nearly equal in size with 

 the anterior one, strongly cusped; third much flatter and 

 more equalling the narrow crowned molars in size and 

 shape. Bony palate strongly extended posteriorly. Palate- 

 ridges seven in number, the anterior six regularly arched, 

 equidistant, the posterior one has a triangular form and 

 is separated from the other ones by a rather wide interval. 

 Wing-membrane from the base of the fourth toe.

Rhinarium small, the groove between the feebly promi- 

 nent nostrils passing down to the border of the upperlip, 

 although not making a deep impression on the latter, there 

 are two more slight impressions on the border of the up- 

 perlip ; lowerlip divided by a rather deep groove into two 

 cushions ; at the base of the outer margin of the ear a 

 slightly triangular lobule. Upper incisors in pairs, very 

 small, set at intervals somewhat wider apart than in the 

 Java-species, the outer ones a trifle larger, upper premolars 

 more triangular than in the Java-species, the anterior 

 rather close to the canine, the second at equal distances 

 from first and third, posterior upper molar much smaller
