 with o-reat agility, often making considerable jumps. If disturbed in the daytime it 

 moves quite slowly, almost like a chameleon. — E,. B. W.]

 A member of the B. leachi group, the limbs being thickly covered with hair. 

 Size and general characters about as in B. leachi. Fur loose and shaggy, very 

 abundant, its limits not sharply defined as in B. leachi; that on the head about 8 mm. 

 in length, mixed with a large number of much longer hairs, attaining over 20 mm. On 

 the back the fur is thick and woolly, passing out on to the proximal half of the upperside 

 of the forearms, and continued thickly down the hind-limbs and the wing-membrane, 

 external to them, to the ankles, the feet being also thinly clothed above. Interfemoral 

 thickly furry above, except just along its posterior margin. Below, the wings are 

 thinly hairy to a point level with the middle of the forearm, the hind-limbs and 

 interfemoral membrane being also less thickly haired than on the upper surface. 

 Ears narrow, rather longer than the muzzle. Palatal ridges as in B. leachi. 



General colour above bistre-brown, becoming warmer posteriorly; head darker. 

 Under surface near broccoli-brown, but with a yellowish suffusion ; some of the longer 

 hairs quite yellow. 



Skull rather more delicately built than in B. leachi, the bones thinner and lighter, 

 ■muzzle rather longer and narrower; postorbital processes very thin; anterior palatine 

 opening unusually broad. 



Teeth conspicuously smaller throughout, each molar and premolar slightly shorter 

 and very much narrower than in the allied species. 



Dimensions of the type (measured on the spirit-specimen) : — •
