General characters. — See synopsis. 



Ears. — The ears are moderately long ; laid forward they I'each about 

 three-fourths of the distance from eye to nostril. Anterior border of 

 conch strongly convex immediately above base, then nearly straight to 

 narrowly rounded off" tip. Posterior l)order fiiintly concave immediately 

 below tip, convex through lower half The posterior border terminates 

 abruptly close in front of meatus, and almost directly below anterior 

 base. Six or seven transverse ridges on inner side of conch near poste-
