The height of the body is one-fourth of the total length, and the length 

 of the head is contained 3§ times in the same. The diameter of the eye 

 is exactly one-fourth of the length of the head ; the snout is somewhat 

 longer. The lower jaw projecting in advance of the upper ; the extrem- 

 iry of the upper maxillary bone extending slightly beyond the vertical 

 from the anterior margin of the orbit. An external row of short, stout, 

 couical teeth, the four or six anterior in each jaw larger and longer than 

 those on the sides ; behind the external row a band of villous teeth. 

 Both limbs of the prfeoperculum armed with distant, sharp, spinous 

 teeth ; those on the posterior limb directed upward, while those on 

 the horizontal limb are directed forward ; at the angle of the two 

 borders is one long and stout spine, directed backward and projecting 

 considerably beyoud the posterior border ; posterior border slightly con- 

 cave. Angle of the operculum obtuse. The dorsal fin deeply notched; 

 the fourth spine, being the longest, about equaling half the length of the 

 head ; first and second dorsal spines short. The second anal spine is 

 very stout and striated, and of the same length as the fourth dorsal. 

 Pectoral pointed, the sixth ray being the longest, about one-fifth of the 

 total length. Ventrals inserted behind the pectorals, shorter than the 

 latter and do not extend as far backward.
