line behind it was a red spot on the preopercle and one on the 

 opercle ; a dark brown line crossed the upper part of the eye and 

 extended from the lower margin of the eye downward, inter- 

 secting twice a curved line behind the angle of the mouth; a 

 brown bar on the base of the pectoral ; the first dorsal was cross- 

 barred with brown, the second dorsal, pectoral, and caudal with 

 numerous rows of small brown spots ; the anal and ventrals were

 Creisson JORDAN and SEALE, Bull. Bur. Fisheries 26 (1907) 43. 



The authors state that "this genus is characterized by the 

 naked lower half of cheek and the scaleless interorbital region. 

 There are several rows of teeth in each jaw, the outer row 

 enlarged; scales on anterior part of the body and head small." 



To this can be added body robust, compressed laterally, pro- 

 file convex. Dorsal VI, 1-10 ; anal I, 7 or 8 ; there are 29 to 

 32 scales in a longitudinal series, 10 or 11 in a transverse series, 

 and about 17 before the first dorsal; there are four to six rows 

 of teeth at front of mouth in each jaw, which are reduced to two 

 or three on the sides ; the outer row more or less enlarged, with 

 a pair of lateral backward-curving canines in lower jaw; the 

 tongue truncate, not notched; the anterior nostril tubulate; the 

 caudal broad and rounded.

 breadth approximately equal, and the predorsal region elevated 

 and swollen; the depth of body 3.8 to 3.9, the head 3.3 to 3.4 

 times in length; the snout short, blunt, rounded, 3.4 times in 

 head; the eyes high up, laterosuperior, obliquely placed, close 

 together, 1 to 1.3 in snout; the convex interorbital space half 

 or a trifle more than half an eye diameter in breadth ; the oblique
