Head and muzzle as in H. suillus ; but the nostrils are differently 

 shaped. Each nostril forms a distinct tube directed sublaterally, 

 -with a circular aperture marked by a very smaU notch on the outer 

 and upper margin. The central part of the upper lip is cut off by 

 a small but distinct groove beneath each nostril, the centre is con- 

 cave, the sides project and support the base of the nasal tube on 

 each side. Ears small, almost regularly oval ; the inner margin of 

 the conch evenly convex, the outer margin similarly convex in the 

 upper two thirds, the lower third slightly flattened opposite the 

 base of the tragus, and terminating in a small but very distinct 

 rounded lobe. Tragus very acutely pointed, tapering, slightly curved 

 outwards ; lower fourth of outer margin straight, sloping slightly 

 outwards, with a rounded projection opposite the base of the inner 

 margin, and a second point slightly higher up, where the tragus 

 attains its greatest breadth (Plate XVII. fig. 1, ear, enlarged 2|). 



Thumb very long, armed with a large strong claw. Wings to the 

 base of the claws. Interfemoral membrane large ; last caudal ver- 

 tebra and half antepenultimate vertebra free. 



The whole body is thickly covered with hair ; both surfaces of the 

 ear-conch are clothed, the inner surface less densely ; the fur on the 

 muzzle is short ; but the short fur extends almost to the ends of the 

 nasal tubes, and between them a few hairs pass down to the lip. 

 Upon the wing-membrane the fur is thin but long, extending as far 

 as a line drawn from the elbow to a point on the free margin of the 

 membrane nearly half an inch from the ankle ; the back of the 

 forearm, as far as the base of the claw of the thumb, is covered with 

 short golden-yellow fur, which also extends upon the third finger 

 as far as the end of its second phalanx, and upon half the metacarpal 

 bone of the fifth finger ; the interfemoral membrane is covered 

 with very long hair, which forms a dense fringe along its free 

 margin, extending also upon the legs and backs of the feet, and 

 projecting beyond the extremities of the toes. Beneath, the wing- 

 membrane is covered as far as a line drawn from the elbow to the 

 knee ; and the whole interfemoral membrane is clothed with short 

 bright silvery hairs. 



Pur on the upper surface black, with bright golden-yellow ex- 

 tremities, more distinct in the middle of the back ; beneath black, 

 the extremities of the hairs silvery white, the white being most 

 conspicuous beneath the lower jaw and upon the neck and pubis.
