Vespertilionine Bat from East Africa. 461 
coppery or cinnamon (Dr. Hinde speaks of the colour as 
“‘bronze’’). Under surface paler brown, the tips of the hairs 
becoming almost white in the pubic region. 
Fur above not extending on to arms or wing-membranes, 
though there are a few fine hairs on the thumbs; but the 
legs are clothed as far as the knee, the backs of the feet are 
finely hairy, and the basal half of the interfemoral is thinly 
covered with fine and inconspicuous hairs. Below the wing- 
membranes are finely clothed nearly as far outwards as a line 
from the elbow to the knee, but the interfemoral membrane 1s 
more nearly naked than above. No trace of an interfemoral 
fringe. 
Kars large, much larger than in Vesperé¢lio, but not so large 
as in Plecotus, Otonycteris, or Histtotus ; not connected across 
the forehead with each other. Inner margin with a distinct 
basal fold, ending below in a narrow lobe; its basal third is 
strongly convex forward, so that the basal line is at right 
angles to the upper two thirds, which are very slightly con- 
vex and pass gradually into the rounded tip; outer margin 
nearly straight above, slightly convex below; antitragus low, 
half-oval, marked by a distinct notch behind. Tragus un- 
fortunately damaged in the type on both sides, but enough is 
left to show that it is long, broad at base, with a slightly 
concave inner margin and a broadly rounded tip. 
Wings of normal Vespertilionine proportions, the meta- 
carpals of the third, fourth, and fifth digits approximately 
equal in length. Insertion of wing-membrane at base of the 
digits, so far as can be made out in the dry skin. Calcar 
reaching about halfway towards the tip of the tail; post- 
calcaneal lobule present, but very narrow. ‘lip of fourth 
finger T-shaped, or even slightly spatulate. Membranes and 
ears uniformly brownish grey, except that the wing-membrane 
from the tip of the fifth finger to the ankle is edged with 
whitish. 
Skull very thin and papery, long and narrow, low, smooth, 
and scarcely ridged at all. Nasal notch comparatively 
shallow. Intertemporal region not strongly constricted, the 
intertemporal but little less than the interorbital breadth. 
Palatal notch penetrating to the level of the middle of the 
canines. Palate narrow, the greatest breadth across the outer 
corners of m.’ going nearly three times in the total length of 
the skull; its posterior part produced behind the molars a 
distance equal to the combined lengths of p.* and m.'. 
Upper incisors slightly convergent, of about the same 
relative proportions as in the Serotine, the inner one long, 
with a secondary postero-external cusp near its tip and a small
