Body robust, more than half of the total length. Head broad. Snout 

 short, blunt, narrowed forward, subangular. Nostrils near the lip, distinct 

 from the mouth and far apart; valves not extended on the internarial space, 

 short, blunt, without cirri. Mouth wide, greatly arched. Teeth three to five 

 cusped, broad based, excepting the symphyseal which are lanceolate, in §1, U 

 and ti rows. Spiracle small, near the eye. Gill openings small, two above 

 each pectoral. Outer angle of pectorals blunt, outer angles of the other fins 

 broadly rounded. Origin of first dorsal behind the middle of the total length, 

 above or slightly in front of the middle of the bases of the ventrals, distance 

 from the second dorsal varying in different individuals. Second dorsal smaller 

 than the anal and opposed to it. Anal smaller than first dorsal, bases about 

 equal, commonly about one and one fourth times the length of the base of 

 the second dorsal. Largest individuals at hand measuring two feet six inches 

 in length. 



Greyish brown to brown, spotted and transversely banded with darker. 

 The bands are irregular, not always present; in cases there are about twelve: 

 the first across the snout, the second across the crown and eyes, and five or six 

 occur between the eyes and the dorsal. The lower surface is dark and the spots 

 are indistinct. A large blotch of darker appears on each side of each of the fins. 



Specimens from California differ from the type (from Chile) mainly in being 

 somewhat darker.
