204 On a new Bat from British East Africa. 



case is decidedly more flattened and less dome-shaped ; and 

 both nasal and anterior jjalatal notches are much deej)er*, the 

 latter reaching nearly to the line of the front of m.\ 



Type " Scotojjhilua'^ alhofuscus, 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. hirundo, 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, Scotoecus is even more nearly 

 allied to the American JSycticeius, which sliares with it the 

 triangular m.^ and more complicated r/i.3, but still has, like 

 Scotojjhilus, the marked disproportion between the sizes of 

 the two lower premolars, the canines rounded in front, and the 

 comparatively shallow nasal and prei)alatal notchc>'. 



Scotcecus Hindei, 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. Ears 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- 

 calcaneal 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 i.\ going only about three times in 

 the distance from it to the occiput ; prepalatal notch reaching 

 to the level of the front of w.* ; 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 35 millim.; height of ear 12, of tragus (on inner 

 edge) 2 •4. 



* At least in 6'. hirundo and Hindei, the skull of 'S'. alhofuscus being 

 broken.
