 to the base of the tail ; head 3.2-3.4 in the same. Eye 4.6-4.7 

 in the head, 1.4-1.5 in the snout, and 1.3-1.4 in the interorbital

 first dorsal ray 2.9, pectoral hu 1.06, and ventral fin 1.2-1.3

Eye placed well below the profile of the head, the 

 interorbital space very convex ; its length is much less than 

 that of the snout, and is only about one-third greater than 

 its distance from the preorbital margin. Nostrils close 

 together, nearer the eye than the end of, the snout, the 

 anterior with a free dermal lobe. Maxillary naked, reaching 

 a little beyond the vertical of the anterior orbital margin. 

 Cheek with seven rows of scales, operculum with about ten ; 

 three and a half rows on the temporal region. Naked 

 surfaces of the upper portion of the head, snout, preopercular 

 limb, and mandible covered with minute pits and muciferous 

 canals. Preopercular margin finely serrated posteriorly, the 

 serrae enlarged on the angle which is produced slightly 

 backward. Some rather strong canines anteriorly in each 

 jaw, which become smaller on the sides ; behind these is a 

 band of villiform teeth which extends onto the sides of the 

 upper jaw, but is confined to the front in the lower. A 

 broad triangular patch of villiform teeth on the vomer, and 

 a narrow elongate patch on each palatine. Suprascapular 

 serrated.
