regions being so distinct from one another in general appear- 

 ance, and have, besides the characters given by Uobson, the 

 very important difference in tlie incisor teeth. 



The first npper incisor in Olauconycteria is bitid, having 

 an outer or rear cusp. 



Glauconycteris Fioweri, sp. n. 



Colour above pale fawn, the bases of the fur greyish ; the 

 lower side cream-colour, yellower on the throat, ]ialer on the 

 belly. The fur on the forehead ends in a point barely in 

 advance of the eyes, and the furred area is limited in extent 

 in all directions, barely encroaching on to the upper arms, 

 and leaving the tail and legs entirtdy bare. The skin of the 

 face and ears is nearly black and naked, with the exception 

 of a few short hairs more conspicuous round the lips. The 

 wing-membrane is pale and transparent, with the veins and 

 lines showing slightly darker ; the posterior portion in front 

 of the tibia? and the distal portion of the intei femoral mem- 

 brane is yellowish white. Tlie upperside of the forearms, 

 legs, and tail, and all the proximal portion of the wings and 

 interfenioral membrane, are thickly studded with dark warty 

 papilla?. 



The measurements of the type taken by the collector from 

 the animal in the fle?h, an adult male, are: — Head and body 



47 niillim., tail 34, hind foot 5"0, ear 12, forearm 35. 



The specimen in spirit gives the following measurements : — 

 Head and body 42, tail 34, hind foot 5*8, ear 12, forearm 

 36-5. 



In size and general colour this bat somewhat resembles 

 Scotophilus SchJieffeni: the body-colour is, however, paler 

 ab'jve and blighter on the lower parts, and the furred area is 

 less extensive ; but the paler wing-membrane, the dark face, 

 and the extraordinary shagreening on the forearms, tail, and 

 surrounding membranes distinguish this new species at a 

 glance. 



The skull is readily distinguished from that of Scotophilus 

 by its rounded form and short facial portion ; the lower jaw 

 is likewise more rounded or blunter.
