Nyctinomous bivittatus, Heiiglin, Nova Acta Acad. Leop.-Carul. 

 Nat. Cm: 1861, p. 13; Dobson, P. Z. 8. 1876, p. 722. 



Ears conjoined by a low band, very slightly raised above the 

 muzzle ; tragus very small, quadrate ; upper lip grooved by vertical 

 wrinkles. No gular sac in male or female. Base of the thumb 

 with a remarkably large circular callous pad. Wings from the 

 middle of the tibise. Fur above umber-brown, the extremities of 

 the hairs conspicuously tipped with grey, especially on the top of 

 the head, where either side is streated with grey, and on the 

 shoulders and middle of the back spotted over with the same 

 colour ; beneath similar, but paler. Distribution of the fur and 

 dentition as in N. plicatus.

Hab. N.E. Africa (Bogos Land). 



Type in the collection of the Stuttgart Museum*. 



This species is very closely allied to N. plicatus, of which it may 

 be considered the African representative.

 of the upper incisors beneath ; outer and inner margins continuous, 

 evenly convex above, the inner margin with three minute horny 

 points ; autitragus well developed, separated by a deep notch, quad- 

 rangular, with shortly rounded angles, the length of its base but 

 slightly exceeding the depth of its anterior margin ; tragus small, 

 quadrate, its superior margin directed upwards and inwards, a small 

 projection at the base of its outer margin ; keel of the ear-conch 

 large, thickened, expanded, and flattened externally in its lower 

 third ; extremity of the nose projecting very much, the distance 

 from the anterior margin of the nostril to the margin of the upper 

 lip exceeding the diameter of the base of the antitragus ; upper lip 

 with vertical wrinkles (Plate XXII. fig. 3). 



Wings from the middle of the tibia). No gular sac in male or female. 



* The writer desires to express again his obligations to Dr. Krauss for the 

 (i)iportuiiity aflorded him of examining the type of this species.
