84 MR. R. F. TOMES ON BATS FROM S.W. AFRICA. [Jan. 22, 



positions. I have two specimens which were collected by INIr. An- 

 dersson at Lake Ngama. 



The top of the head is on the same plane with the face ; the muzzle 

 is moderately obtuse, a little more so than in the >S^. kuhlii of 

 Europe ; the nostrils are slightly tubular, ovoid, and opening sub- 

 laterally ; between them is a shallow notch, which passes into a kind 

 of narrow groove or canal, and is continued along the mesial line of 

 the snout until it meets the fur of the forehead. The ears are con- 

 siderably shorter than the head, triangular, rather longer than wide, 

 a little rounded at the ends, and with scarcely a trace of external 

 emargination or scooping out. There is no prolongation of the outer 

 margin along the face anteriorly, to the root of the tragus. The tra- 

 gus is about half the length of the ear ; its greatest breadth is at one- 

 third from the bottom, from which part it curves evenly to the tip, 

 which is narrow and rounded ; the inner edge is straight or a little 

 concave, which gives the tragus somewhat of an inward tendency ; in 

 the outer margin, near to the base, is a notch, and below it a distinct 

 but rounded lobe. 



The thumb is small, its penultimate phalange the longest, its claw 

 small and weak. The feet are rather small, the toes taking up more 

 than half their length, the claws of medium size. 



The wing-membranes extend to the root of the toes. The wings 

 themselves are of medium size, and the membranes slightly translu- 

 cent, but nowhere papillated. 



The fur of the forehead extends to more than halfway between the 

 root of the ear and the nostrils ; sides of the face scattered with fine 

 short hairs ; over the eye a tuft of straight black hairs ; and on the 

 upper lip a straggling moustache of shorter and finer ones. The fur 

 of the back extends on to the membrane beneath the humerus, and 

 sparingly on to the interfemoral membrane ; beneath, it encroaches 

 on the membranes for a short distance all round the body. 



On all the upper parts the fur is bicoloured, almost black at the 

 roots for half its length, the remaining part of a dark brown colour, 

 sometimes approaching an umber-brown, but more frequently dark 

 greyish-brown. Beneath it is also bicoloured, brownish-black for 

 two-thirds of its length, and tipped with whitish-brown ; about the 

 chin and sides of the neck it is tinged with chestnut, and on the 

 pubes it is nearly cream-coloured. Cutaneous system dark brown, 

 claws pale brown. 



The cranium in its general outline very greatly resembles that of 

 S. kuhlii and that of »S. jiipistrellus : but its similarity to the former 

 of these is the most striking ; to this species, indeed, it is rather 

 closely allied, although perfectly distinct. 



Dentition : M. ^-=? ; Can. ^^ ; Premol. ^^ 5 ^^ol. 1^=^^. 



The upper iucisors are very unequal in size ; the outer ones very 

 small, and pointed ; the inner ones twice the length of the outer ones, 

 slender, and pointed, with an ill-defined second point, which is situated 

 outwardly. The canines are rather slender, and have a regularly 

 disposed cingulum. The premolar tooth is rather longer than the
