Total length : 1 foot 6 inch. 



The length of the head is 4| in the total ; the horizontal diameter 

 of the orbit is ~ of the length of the head ; the distance of the eyes 

 across the head two such diameters. The long helmet is finely sha~ 

 greened to between the eyes, where its breadth is ^ of its length ; the 

 occipital point is narrow triangular, occupying half the interval between 

 the occiput and the dorsal spine, and receiving in a notch the point of 

 the second interspinal. The mastoid and suprascapular processes form 

 an elongated arch surrounding the opercle and nearly touching the 

 humeral. The latter is elongated triangular, its length twice its height. 

 The opercle is finely shagreened like the rest of the bones forming the 

 helmet, and has besides some radiating lines. The greatest breadth of 

 the head nearly equals its length, and also the greatest vertical diame- 

 ter of the body, in front of the dorsal spine. The card-like teeth are 

 disposed on narrow bands in the jaws and on the vomer.
