1876.] MR. G. E. DOBSON ON THE MOLOSSI. 725 



Thumb long ; feet large ; wing-membrane from the middle of the 

 tibiae. 



Fur above and beneath very short; above white at the base, 

 terminal three fourths of the hairs deep reddish-brown ; beneath, 

 yellowish-white or pale reddish-yellow ; the shoulders, sides of the 

 neck, chest, and abdomen reddish brown. On the upper surface the 

 membranes are almost quite naked ; beneath, the wing-membrane is 

 covered with very short fine pale yellowish-white hairs as far out- 

 wards as a line drawn from the middle of the humerus to the knee ; 

 and similar short fur appears upon the interfemoral membrane. 



First upper premolar very small, scarcely visible without the 

 aid of a lens, in the outer angle between the closely approximated 

 canine and second premolar ; sometimes deciduous. Lower incisors 

 crowded. Length (of an adult $): head and body 2" -9 ; tail 1"*8, 

 tail free from membrane 0"*95 ; head 1" # 05 ; ear 0" - 75, tragus 

 0"*lx0" - 03; forearm 1 "85 ; thumb 0""45 ; second finger — meta- 

 carp. l"*85, 1st ph. 0""85, 2nd ph. l" - 25; third finger — metacarp. 

 1"'8, 1st ph. 0"'7, 2nd ph. 0"*65 ; fourth finger — metacarp. 1"*2, 

 1st ph. 0"'55, 2nd ph. 0"-22 ; tibia 0"-65 ; foot and claws 0"-4. 



Hab. Africa (iVngola, Coanza river) ; Madagascar (Mahanora). 



Nyctinomus hepaticus, Heuglin (Nov. Act. Acad. Leop.-Car. 

 xxiii. 1864, p. 14), appears from the original description to be very 

 closely allied to, if not identical with, N. angolensis. But Dr. 

 Krauss informs me that the type is not in the Royal Zoological 

 Museum at Stuttgart, where the types of the other species of Bats 

 described by Herr von Heuglin are preserved ; and he doubts 

 whether any specimen of the species was brought by the descriherto 

 Europe. As the description is very imperfect, and as the type cannot 

 be found, this species must remain doubtful.

Nyctinomus miarensis, Grandidier, Rev. et Mag. Zool. 1869,

Nyctinomus unicolor, Grandidier, /. c. 1870, p. 49. 



About the same size as N. cestoni. Ears shorter than the head, 

 united on the muzzle by a band about 0"*15 high in the centre, at 

 a distance of 0"*2 behind the extremity of the nose; ear-conch 

 broadly rounded off above, the outer and inner margin continuous ; 

 antitragus longer than high, irregularly quadrate, the shortest side 

 above, separated by a deep notch posteriorly ; tragus narrow, much 

 longer than broad, shortly rounded off above, inner margin slightly 

 concave, outer straight, in general shape altogether different from 

 that of any of the previously described species ; keel of the ear- 

 conch well developed, prominent, thickened and expanded in lower 

 third, upper lip very expansible, deeply grooved by vertical furrows. 



Thumb short, with a large circular callosity. Wings from the 

 lower end of the tibiae. Fur above dark brown, beneath brown with 

 slightly ashy extremities.
