case is decidedly more flattened and less dome-shaped ; and 
both nasal and anterior palatal notches are much deeper*, the 
latter reaching nearly to the line of the front of m.'. 
Type “ Scotophilus” albofuscus, ‘Thos. 
In my first description of it S. albofuscus was only 
placed provisionally and with great doubt in Scotophilus. 
Mr. de Winton, in describing S. A¢rundo, expressed his opinion 
that neither were properly congeneric with the previously 
described species, and, now that a third member of the group 
has turned up, I think it advisable to form a special genus 
for all three. In the characters above noted the three pre- 
cisely agree, and differ from any of the members of the true 
Scotophilus. 
In some respects, perhaps, Scotwcus 18 even more nearly 
allied to the American Nycticedus, which shares with it the 
triangular m.° and more complicated m.3, but still has, like 
Scotophilus, the marked disproportion between the sizes of 
the two lower premolars, the canines rounded in front, and the 
comparatively shallow nasal and prepalatal notches. 
Scotecus Hindet, sp. n. 
Size largest of the genus. Fur close and soft, hairs about 
3 mm. in length on the back; not extending either above or 
below on limbs or membranes, except slightly on and around 
the base of the tail. General colour above chocolate-brown, 
the bases of the hairs darker; below the colour is paler, the 
hairs being brown basally and dull buffy terminally. Muzzle 
and chin blackish brown. ars of medium length, their 
tips rounded, with a slight and even concavity below them. 
Tragus short, of equal breadth above and below, an indistinct 
lobe at its external base. Wings to the metatarsus. Post- 
caleaneal lobe well-defined. Penis very long, apparently 
provided with a bone. 
Skull very similar to that of S. hirundo, but larger and 
heavier throughout ; nasal notch very deep, its depth, 
measured from the base of ¢.", going only about three times in 
the distance from it to the occiput; prepalatal notch reaching 
to the level of the front of m."; sagittal crest fairly developed. 
Upper incisors short, stout, strongly convergent. Lower 
incisors transverse, slightly overlapping. Anterior lower pre- 
molar three fourths the height of the posterior one. 
Dimensions of the type :— 
Forearm 85 millim.; height of ear 12, of tragus (on inner 
edge) 2:4,
