Disk wide, being from one-third to one-fourth wider than long, front of head 

 obtuse with the snout slightly produced at its extremity. Tail of somewhat 

 vai'ying length, but equal to about one-half of the total length. Anterior edge of 

 the disk undulated and scarcely passes beyond a line drawn from the end of the 

 snout to its rounded angle : the hind margin of the disk convex, one-fourth 

 shorter than the front edge. Eyes — rather large, their diameter being about one- 

 fourth of that of the snout, and from lj to 1| in the interorbital space. The 

 spiracles placed close behind the orbits, than which they are somewhat smaller. 

 Mouth arched, and its width equals nearly half its distance from the end of the 

 snout. Nostrils ratlin- wide asunder, the distance between their outer borders 

 equalling about that from the end of the snout. Teeth — large, those in young males
