diameter of eye 3f to 4 in the length of the head; snout short, 

 its width between the posterior nostrils equal to or a little more

 vertical from the anterior border of the eye, its length from the 

 tip of the snout 4- to 4i in that of the head. 12 or 13 gill- 

 rakers on the lower branch of the anterior arch. The origin of 

 the first dorsal is midway between the base of the last soft ray 

 and the extremity of the snout or a little nearer to the former; 

 the space between the origin of the second dorsal and the base of 

 the caudal 1} to 1^ in the remaining length; second dorsal higher 

 than the spinous, its longest ray 1^ to Ig- in the head : ventral 

 subequal to the head, the fourth ray produced, extending to or 

 beyond the vent: pectoral with 13 or 14 rays, about as long as 

 the ventral : caudal moderate, 3^ to 4 in the total length; peduncle
