The pilotfish is pelagic in all tropical and temperate seas; it 

 is occasionally taken on our coast as far north as Provincetown 

 .Mas., but is not at all common. It was reported at Woods Hole 

 Mass, by Prof. Baird in 1871. The young are developed in the 

 open ocean and are so different in appearance from the adult 

 that they have been described as a distinct genus. The fish has 



no economic value.

 .and breast not trenchant; head usually more or less conical, 

 not very blunt; mouth comparatively large, with broad bands of

 broad, strong, supplemental maxillary bone; premaxillaries pro- 

 tractile; scales small; lateral line slightly arched, forming a keel 

 on the caudal peduncle, not armed with bony plates; sides of 

 head with small scales; first dorsal with about seven low spines, 

 connected by membrane; second dorsal very long, elevated in
