Disk broad and rounded, its length i.i in its breadth. 

 Snout broadly rounded, with a median rounded papilla, and 

 confluent with the anterior margins of the pectorals which are 

 almost straight. Ihe lateral margins of the pectorals are 

 rounded, as is the angle between them and the posterior 

 border. The distance between the outer margins of the eyes 

 is greater than that of the latter from the edge of the disk. 

 Preoral length much less than the distance between the outer 

 margins of the spiracles and 2.7 in the head to the last gill- 

 opening. Width of the spiracles one-third the preoral length. 



Nasal lobes produced backwards and outwards, the exterior
