THE SEA-BULLHEAD. 3 



is bounded anteriorly by the two nasal spines and the 

 prominent ends of the premaxillary pedicles. There are 

 no serratures on any of the spines or bones of the head 

 or shoulder, in which respects this species differs from 

 the Father-Lasher. 



The top of the head is sprinkled with soft conical 

 pimples, and the skin generally is naked and smooth, but 

 some small, circular, minutely-spiniferous scales exist on 

 the back and posterior surfaces of the pectoral rays.
