VespertiUonine Bat from Angola. 205 



I have now been able to make a careful study of this 

 specimen, and have come to the conclusion that it represents 

 a new genus, which may be called 



CiSTUGO, gen. nov. (yespertiUomdce) . 



Allied to Myotis, but with differently proportioned teeth 

 and with glands in the wings. 



Skull essentially as in Myotis, but the brain-case not 

 specially vaulted and the muzzle rather less ])iuclied in laterally. 



Dental formula as in Myotis. 



Incisiors of the same essential structure as in Myotis, but 

 shorter. (canines similar. [Small premolars subequal, 

 minute, not half as laige as the incisors, short, stumpy, 

 quite without the similarity to a minute canine shown at least 

 by the anterior one in Jlfyotis, their tips barely rising to the 

 level of the cingulum of the canine, the two closely pressed 

 togetlier and just filling the space between the canine and the 

 large premolar. Large premolar with an unusually well- 

 developed antero-internal cusp, as high as the large inner 

 cusp of the molars. Lower incisors as in Myotis; canines 

 proportionally short, barely rising as high as the posterior 

 premolar; premolars all with their antero-posterior less than 

 their transverse diameter, the two small ones closely crowded 

 together between the canine and posterior premolar. 



General external characters as in the smaller species of 

 Myotis. Tragus of medium length, differing from that of 

 most species of Myotis by being broader slightly above its 

 base than at the base, its inner and outer edges both slightly 

 convex. 



Wings with peculiar thickened glands in them on the 

 outer side of the forearms distally ; tiiree present on the left 

 side and two on the right in the single specimen, but the 

 situation of the third one is perceptible in the right wing, so 

 that the normal number is probably three ; the glands them- 

 selves about 3-;V5 ram. in length by 1-1*5 in breadth, more 

 sharply outlined than tiie corresponding glands in Fizonyx; 

 also situated closer to the forearm than in that genus, less in 

 the centre of the wing. 



Type:- 



Cistugo seahrce, sp. n. 



General appeal ance that of a Ptpistrellus, say P. kuhlii, 

 to which there is a considerable resemblance in size and 

 colour. Ears of average size, their anterior margin convex 

 at base, then nearly straight to the tip, which is narrowly
