Disk nearly twice as broad as long; angles acute, blunted. Tail slender, 

 short, longer than the body in young, shorter in old, without a spine. Eyes 

 prominent, pupil vertical. Teeth minute, pentagonal, with point directed into 

 the cleft of the mouth, or with two or more points. The bands extend nearly 

 to the angles. The teeth appear to vary greatly with age. Day states that 

 they are small like flattened tubercles, as broad as long in adults, twice as broad 

 in young. On jaws 12 inches across the gape, from a specimen 18 feet in width 

 the rows were ||B, jaws of 4 inches in width lu, and Cantor found the rows 

 to be §5 on the jaws of one 30 inches in width. The last specimen had a total 

 length of about 45, from snout to vent 15^, and a width of 30| inches. Doisal 

 between the ventrals, subtriangular, hind margin short, origin slightly in 

 advance of the ventrals; in the figures published by Russell and by Day the 

 end of the dorsal is some distance in front of the ends of the ventrals. 



Young intense purple on the back, with ventral surfaces, sides of head behind 

 the eyes, tip of dorsal, outer margins of ventrals, outer and lower surfaces of 

 rostral fins, and tail to ends of ventrals white; jaws, margin of snout, and tail
