 middle ones chevron-shaped, the distal one heart-shaped, the basal 

 ones divided into two rounded plates ; the plates under the apex of 

 the digit large, together cordtform. Upper surfaces covered with

 spine-like tubercles. Eostral pentagonal, completely divided medi- 

 ally ; nostril pierced between the rostral, the first labial, and three
