Ears considerably longer than the head, oval, broadly rounded off 

 above ; outer and inner margins slightly convex, the outer termin- 

 ating abruptly midway between the base of the tragus and the 

 angle of the mouth. Nose-leaf long, narrow, truncate above, with 

 straight not converging sides ; its horizontal base circular, with a 

 free margin, forming a concave disc above the extremity of the 

 muzzle, with the opening of the nostrils at the bottom of the con- 

 cavity; its anterior surface with a prominent central longitudinal 

 ridge, corresponding to a deep groove on the posterior surface of 

 the leaf, expanded below into a circular disc, the margins of which 

 conceal the nasal apertures. The projecting lip has a prominent 

 triangular naked space in front, divided by a longitudinal groove. 

 Wing membrane /rom the back of the foot, attached close to the base 

 of the outer toe ; interfemoral membrane square behind. Calcaneum 

 short, feeble; tail short, concealed within the base of the inter- 

 femoral membrane. Fur of a slaty blue colour, extends densely upon 

 the humerus and muscular part of the forearm. The four lower incisors 

 are equal in vertical extent, bifid, and not crowded.
