 the 11th spino of the dorsal. The pectoral reaches to below the 

 12th spine; it is falcate, its length equal to length of head with-

 other related species, because the entire body is scaly. The 

 lateral line curves downward from a point under the origin of 

 the second dorsal. D. XIV, i, 13-IX; A. i, 12-YIII; V. I, 5.

The tunny is the largest fish of the mackerel familv, reachina^ 

 a length of 10 feet or more. It is pelagic, but comes to all 

 warm coasts, northward to England, Newfoundland, San Fran- 

 cisco, and Japan. In our waters it appears usually in summer 

 and is often taken in rather large numbers off Block Island, and 

 on Cape Cod and Cape Ann. On account of its enormous size 

 and great strength, it is often destructive to the fishermen's 

 fixed IK ts. 



Dr Storer says it comes into Massachusetts bay about the 

 middle of June ami remains till early in October. It was not 

 uncommon to observe 50 or more in a day at Provincetown. It 

 feeds on menhaden, mackerel, whiting, dogfish and other small 

 fishes. The usual implement of capture at first was the har-
