This is the largest known species of the genus. The cars are 

 very large, the lips acuminate and hhmtly pointed, the outer margin 

 concave below the tip and divided from the large and long antitragus 

 bj a deep re-entering angidar notch. 



Nose-leaf greatly developed and peculiar. The anterior leaf very 

 large, projecting over the lip in front and at the sides, deeply in- 

 cised in tlie middle. Sella expanded on each side of the base of 

 the ex'ect jirocess into a rounded fiat disk, one above each nosiril. 

 The transverse erect process is much higlier than the short longi- 

 liidinal posterior buttress, the Tree maj-gin of the latter is rounded.
