Head very slightly elevated above tlie face-line ; muzzle conical, 

 not concave between the crown of the head and anterior extremities 

 of the nasal bones ; extremity of the nose projecting slightly beyond 

 the upper lip, with a very shallow concavity between the nostrUs, 

 which open sublaterally. Ears ovate, with rounded tips directed 

 outwards ; the outer margin is abruptly and irregularly concave 

 beneath the tip for about one third its length, then gradually convex 

 and terminating opposite the basal lobe of the inner margin in a 

 small lobe : tragus long, narrow, and obtusely pointed ; inner margin 

 straight, outer margin curved outwards at the base for about one 

 third of its length, then ascending straight, equally inclined to the 

 inner margin ; on the curve at the base a very small lobule is 

 placed. 



Wing-membrane very broad, attached to the base of the toes, 

 remarkably variegated with orange and rich brown-black. The 

 portions of dark-coloured membrane are triangular in form, and 

 occupy the spaces between the second and third and third and 

 fourth fingers, and also the space included between the fourth 

 finger and a line drawn between the carpus and the ankle. All the 

 remaining portions of membrane, including the ears and interfemoral 

 membrane, are orange. The orange-colour extends in narrow lines 

 along each side of the fingers (the bones of which are of the same 

 hue), and is dispersed over the dark triangular spaces in dots and 

 streaks. 



The fur of the head extends upon the face, forming a fringe along 

 the margin of the upper lip ; from the back it extends upon the 

 humerus and antehumeral membrane, covering half the extent of 

 the latter ; on the wing-membrane it is confined to a narrow space 

 along the sides of the body and terminates rather abruptly : behind, 

 it passes on to the interfemoral membrane, covering nearly half its 

 surface, and, leaving the posterior half of the interfemoral and 

 calcanea bare, reappears on the back of the toes. Beneath, the fur 

 of the thorax extends along the humerus tq^the elbow-joint, and as 

 far as a line drawn from the elbow to the knee-joint the wing-mem- 

 brane is covered with a few scattered hairs ; behind, the fur of the 

 abdomen extends upon the interfemoral membrane, rather densely 

 at the root of the taU, but quickly thins out into a few very short 

 scattered hairs, which extend over half its surface. 



Dentition quite similar to that of Y. muriniis ; the second upper 

 premolar very small, and in many specimens difficult to distinguish 

 even with the aid of a lens.
