The rock bass has a robust oblong body; its depth is con- 

 tained two and one third times in the total length without 

 caudal, the head two and four fifths in this same length. The 

 caudal peduncle is stout, almost as deep as long. The dorsal 

 profile is rather steep; strongly concave over eye. The eye 

 is large, about one fourth the length of head, equal to snout. 

 The mouth is large, the maxillary reaching to vertical from 

 posterior end of pupil. The heavy lower jaw projects slightly. 

 The vomer, palatines, tongue and pterygoid bones all toothed; 

 the teeth on the tongue in a single patch. The pharyngeal 

 teeth are sharp. The opercle ends in two flat points; preopercle 

 serrated at its angle. Gill rakers long and strong, less than 

 10 in number; six branchiostegals; scales large, those on the 

 cheeks in about eight rows; caudal rather deeply emarginate. 

 The dorsal base is about one and one half times as long as that 

 of the anal. The spines of both fins are stout and rather short. 

 The first spine of the dorsal is over the seventh scale of the 

 lateral line, and the last spine is over the 25th scale. The first 

 soft ray is over the 26th scale, and the last ray over the 35th. 

 The anal origin is under the middle of the spinous dorsal, and
