horizontal diameter 4-15 in the preoral length and 3-85 in the width of the- 

 mouth; interocular width one tenth more than the preoral length. Angle of 

 upper jaw touching a line drawn between the anterior borders of the eyes. 

 Labial folds moderately developed, that of the lower jaw twice as long as the 

 upper fold, which is about one fourth of the ramal length ; a groove behind the 

 angle of the mouth. 



Teeth rather stout and moderately oblique, those of the upper jaw with 

 the tip straight, of the lower with the tip bent somewhat inwards, each with a 

 deep notch behind ; lower jaw without, upper with a median unpaired tooth. 



Gill-slits narrow, the width of the third 1-8 in the distance between the 

 upper angles of the first and fifth and seven tenths more than the eye-diameter; 

 last two gill-slits above the pectoral. 



First dorsal originating a little behind the inner angle of the pectoral, its 

 inner lobe not quite reaching the vertical from the origin of the ventral ; second 

 dorsal very small, its basal length 4-15 in that of the first and 3-15 in its distance 

 from the precaudal pit ; interdorsal space one ninth more than the upper caudal 

 lobe, which is one fourth of the total length; lower lobe well developed, broad 

 and obtuse, its length 2-35 in that of the upper. Anal terminating below the 

 middle and 1-9 time the base of the second dorsal, inserted about four ninths 

 nearer to the caudal than to the ventrals. Pectoral triangular, with both outer 

 and inner angles obtuse, its width 1-25 in its length and 1-1 in the base of the 

 first dorsal, its outer angle extending to below the anterior third of that fin. 

 Ventral fins inserted four ninths nearer to the first than to the second dorsal. 



Dark blue-gray above, lighter below, none of the fins with darker tips or 

 borders.
