der one is a circular space, callous in the middle. The eyes are 

 small and high. The membranes of the gill-covers are exposed 

 to view. 



The ridge of the back is convex. The lateral line runs 

 straight, near the middle of the side, but rises a little at the 

 shoulder. The scales are large in proportion, and adhere firm- 



The dorsal fin is before the middle ; the first of its rays is 

 short, and, with the second, is undivided ; the others are

The back is nearly straight, with a convex edge. The late-
