Description of a Dew Scotophilus from the Gambia, with remarks on some of 

 the allied species; by oldfield thomas, Natural History Museum, London. 



In a further consignment of bats sent to the Natural History 

 Museum from Bathurst , . on the River Gambia , by my friend 

 D,'' Percy Rendali, I find two examples, one adult and the 

 other immature , of the following interesting new species of 

 Scotophilus. 



* Scotoplxilvis allbofixscxis , sp. n. 



Size small ; body stout and heavy compared to the size of 

 the wings. Head very broad and flat; muzzle considerably 

 swollen, the glandular prominences much developed. Ears rather 

 thick and fleshy, especially along their outer edge ; laid forward 

 they reach to just about halfway between the eye and the tip of 

 the nose ; their internal basal lobe scarcely developed at all ; inner 

 margin nearly straight, tip narrowly rounded off; outer margin 

 evenly convex in its upper third, slightly concave in its middle 

 third, and' terminating in a long fleshy lobule running forwards 

 towards the angle of the mouth. Tragus unusually short (see 

 measurements below), its inner and outer edges straight and 

 nearly parallel, tip broadly rounded off, external basal projection 

 fairly well developed. Wings to the metatarsus. Post calcaneal 

 lobe broad and prominent. Extreme tip of tail projecting. 



Fur short and close, scarcely encroaching at all upon the 

 membranes or limbs. Colour of body above and below dark 

 umber brown; naked skin of all those parts which are visible 

 when the wings are folded dark brown or black, i. e. muzzle, 

 ears, lines of arms, forearms and fingers^ wing membranes 

 internal to a line drawn from the elbow to the knee, and whole 

 of hind-limb, interfemoral membrane and tail ; on the other hand
