 orbital stay covering most of cheek; a ridge extending backward from 

 each eye, the two connected by a cross ridge at occiput ; the ridges large 

 and rough, and the space between them concave ; preopercle with 4 spines, 

 the upper very long, straight, and rough, usually reaching past opercle, 

 a little more than \ head; opercular ridge very broad; subopercle with 

 2 diverging spines; a single series of large, rough, granular plates along 

 sides, from opercle to base of caudal, the plates without keel or spine and 

 growing smaller behind; spinous dorsal small, much lower than soft rays;
