the other, and of exactly the same structure as the third, but in some 
cases a little shorter; two very short spines similar to the second 
spine placed close together half way between the fourth spine, and 
dorsal fin; rays of soft dorsal nearly equal in height, except the first 
and last, which are somewhat shorter than the rest, their free tips 
projecting; numerous spines on head, those at the tip of snout and on 
the ridge above eye, at the angle of mouth, and the region of occiput 
being most prominent, especially in young specimen; humeral spine

and usuall}' bifid, pointing backward; the spine thus ends in five

inward; all except a few on outermost row near the angle depressible; 
teeth in maxillary also very irregular in height and arrangement; 
those on outermost row short and pointing outward and generally 
depressible, those near the angle inward; those on inner rows inclining 
inward and nearly all depressible. 
Color of body gray to grayish brown, with numerous lighter dots
