Type in the collection of the British Museum. 
This species resembles V. (Alobus) temminckii, Riipp., but may 
be at once distinguished by the form of the tragus, which is narrowed 
towards the tip and subacutely pointed, by the deeply fimbriated 
margin of the interfemoral membrane, by its much greater size, &e. 
ce. Ears triangular, the outer margin terminating in a distinct 
well-defined round lobe midway between the base of the tragus 
and the angle of the mouth; lobule at base of outer margin of 
tragus very small or absent ;~ postcaleaneal lobe distinct ; wings 
from the base of the toes; base of the thumbs and soles of the 
feet with fleshy pads as in Tylonycteris ; premolars — Sub- 
genus Glischropus. 
3. VESPERUGO NANUS. 
Vesperugo nanus, Peters, Reise nach Mossambique, i. p. 63. 
Resembles V. pipistrellus in the general form of the muzzle and 
ears; but the ears are narrower, and their outer margin distinctly 
angularly emarginate opposite the base of the tragus, terminating in 
a sharply defined, projecting round lobule; the inner margin is 
regularly slightly convex from the base to the tip, which is shortly 
rounded off; the upper half of the outer margin distinctly concave. 
Tragus without triangular lobule or projection at the base, narrowest 
opposite the base, broadest opposite the upper fifth of the inner 
margin, the outer margin sloping inwards above to join the inner 
margin, and form with it a narrow rounded terminal projection 
curved slightly inwards. 
Base of the thumb swollen, rounded, the surface marked with 
deep wrinkles; the sole of the foot similarly swollen aud wrinkled, 
but flat, or slightly concave as in Tylonycteris pachypus ; toes short, 
about half the length of the whole foot. Postcalcaneal lobe distinct, 
rounded, placed on the calcaneum at a distance equal to about three 
fourths the length of the foot from the end of the tibia. Tail as 
long as the head and body, the extreme tip projecting. Above dark 
brown or black, with shining tips; beneath brown or black at the 
base, with ashy extremities. 
Upper incisors nearly equal in length, inner incisors bifid at 
extremities, outer unicuspidate. Lower incisors distinctly trifid, and 
not crowded. Second upper premolar separated from the canine by
