1st ph. 0"-85, 2nd ph. 0"-6 ; fifth finger— metacarp. l"-35, Ist ph. 

 0"-75, 2nd ph. 0"-3 ; tibia 0"-7, foot 0"-5. 



Hah. Madagascar. 



Type in the collection of the Paris Museum. 



This species may be at once distinguished from all the known 

 species of the genus by its peculiarly shaped tragus, which is much 

 longer than broad and narrowly rounded ofi' above.

Ears larger than in iV. angolensis; upper three fourths of the 

 margin of the ear-conch regularly convex, forming almost an arc of 

 a- circle ; inner margins conjoined by a deep band 0"-2 high in the 

 centre ; tragus very smaU, quadrate ; antitragus large, quadrilateral, 

 with rounded angles, nearly as high as long, separated posteriorly 

 by a deep notch, ending abruptly anteriorly close to the angle of 

 the mouth. Upper lip with deep vertical wrinkles. ISTo gular sac 

 in male or female. 



Thumb rather long, armed with a well-developed claw ; wings 

 from the lower third of the tibia. 



Fur very short above and beneath ; on the dorsal surface dark 

 brown, somewhat paler beneath, extending upon the wing-mem- 

 brane along the sides of the body onlJ^ 



Upper incisors short, separated by a small interval in front ; 

 lower incisors 4, crowded ; first upper premolar very small, deci- 

 duous, in the outer angle between the closely approximated canine 

 and second premolar. 



Length (of the type specimen), head and body 3", tail 1""5, tail 

 free from membrane 0"-95, ear 0"-95, tragus 0"-l, forearm 1"'8, 

 thumb 0"-4, third finger 3"-5, fifth finger l"-8, tibia 0"-7, foot 0"-45. 



Hah. Sumatra. 



Type in the collection of the Paris Museum. 



This species is closely allied to N. angolensis, agreeing with it in 

 the position of the minute first upper premolar, which is quite ex- 

 ternal to the tooth-row, in the remarkable length of the thumb as 

 compared with other species of this genus (except N. joTiorensis), 

 and in the peculiar shortness of the fur. It is, however, readily 

 distinguished by the form and size of the ears, and by other cha- 

 racters described above. 

 a. 2 ad., al. M. Lidth de Jeude [C.]. 



The next species is distinguished from all the known species of 

 the genus by the very peculiar manner in which the ears are united, 

 and on this account was made by me the type of a subgenus, 

 Chcerephon (Journal Asiat. See. Beng. 1873, p. 144).
