 formed dorsal fin in a line over it, nearly one inch in length 

 at its base, with about one-third of the fin, which contains 

 from thirty-five to forty very slender rays, in advance of the 

 vertical line of the anal aperture. Between the head and the 

 anal orifice there are on the body of the fish about thirty 

 sculptured plates or segments, and nearly sixty on the tail, 

 diminishing gradually in size as they approach the tip.

 are tinged with yellowish brown, and both are occasionally 

 varied with darker shades of colour on the body. 



The largest specimens seldom exceed nine inches in length. 

 The figure at the head of this subject is the exact size of the 

 specimen from which it was drawn.
