 of the head. Dorsal spines filiform, and projecting beyond the 

 membrane. Colours brownish, with eight or nine rings of a darker 

 tint surrounding the body and wider than the ground-colour ; fins

 the vertical from the anterior margin of the eye. The length of the 

 pectoral is equal to the length of the head, and less than that of the 

 caudal, which is one sixth of the total length. The second dorsal is

Body subcylindrical, naked, or with the posterior part covered 

 with cycloid scales. Head oblong broad and depressed, with the 

 cleft of the mouth horizontal, or very nearly so. Jaws subequal ; 

 snout obtusely rounded ; lips not very thick, the lower with a series 

 of numerous, short, pointed, horizontal teeth. A single series of 

 fixed teeth in both jaws ; the anterior ones in the upper jaw are 

 closely set and tricuspid, anchylosed to groove on the superior surface 

 of the maxilla, those more remote and tiiose in the lower jaw 

 widely set, simple and conical. Behind the tricuspid teeth in the 

 upper jaw, lie several series of young teeth hidden in the gum, 

 which succeed the former teeth as they become worn out or broken. 

 Eyes of moderate size. Two dorsals, the anterior with six flexible
