574 Mr. O. Thomas on a new Genus and 



tail. General colour of fur uniform sandy buff above^ rather 

 paler below, stroii[;ly contrasting with the blackish ears and 

 wings; the hairs unicolor throughout. Ears rather short ; 

 inner margin strongly convex at base, almost straight above 

 to the rounded tip ; outer margin flattened niesially, convex 

 below and ending in a long low antitragal lobe. Tragus 

 short, its inner margin slightly concave, tip rounded, outer 

 margin convex with a well-marked rounded basal lobule. 

 Wings to the metacarpus. Extreme tip of tail projecting. 



Skull slender, with a small brain-case, but widely expanded 

 zygomata. Muzzle remarkably flattened, the space between 

 the orbits quite flat or even concave, the strong supraorbital 

 ridges rising up higher than its central line; as a result the 

 upper profile-line of the skull is decidedly concave in its 

 anterior half, only becoming gradually convex over the brain- 

 case. Nasal notch sharply angular behind. 



Inner upper incisor conical, uuicuspid in the type, but a 

 supplementary cusp may have been worn off; outer incisor 

 similar in shape, about one fourth the size of the inner. 

 Lower incisors crowded, overlapping, tricuspid, the outer 

 notch on each deeper than the inner one. 



Dimensions of the type (measured on the skin) : — 



Forearm 35 mm. 



Head and body (c.) 41 ; tail (c.) 32 ; third finger, meta- 

 carpus 35, 1st phalanx 11, 2nd phalanx 13; tibia 14. 



Skull : greateat length 12'3 ; basal length in middle line 

 10 ; front of canine to back of ni^ 4*5; front of lower canine 

 to back of wg 4*7.

 August, 1899, by W. Dodson. One specimen. 



This little bat has so remarkable a resemblance to Scoto- 

 pUlus Schlieffeni that it was included among the specimens 

 of that species recorded in my paper on the Dodson mammals 

 from Aden*. Now, however, that its skull has been looked 

 at it proves to be a Vespertilio, in which genus its peculiar 

 colour distinguishes it from all described species except 

 V. Floicerif, from which its smooth forearms and unusually 

 flattened muzzle readily separate it. 



I have named this interesting species in honour of my 

 friend Dr. Paul Matschie, of the Berlin Museum, whose notes X
