 most common in July and August. Edwards. 

 Taken by spearing from a "pulpit" on the 

 bowsprit of a sloop or small schooner. 



Probably do not breed locally. Goode. 



Food: Fish and squid. Linton. In one speci- 

 men ii hake (i to 2 feet long) and i menhaden

 Smith, 1898, p. 97; Kendall, 1908, p. 78. 



"Reported by Baird in 1871." Smith. Two 

 others reported by Dr. Smith from Great Har- 

 bor, Woods Hole, September 9 and 10, 1898. 

 The first was seined, the other caught off the 

 wharf. 



Seriola zonata (Mitchill). Rudder-fish; pilot-fish.

 dall, 1908, p. 78. 



Vineyard Sound, Eel Pond, Great Harbor, Quis- 

 set Harbor, Hadley Harbor, Woods Hole, and 

 elsewhere. Smith. Nantucket. Sharp and 

 Fowler. Rather common about piers, pound- 

 net stakes, vessels, and under floating seaweed 

 and eelgrass. Present from July to October.

 butterfish ) . Linton .

Seriola lalandi Cuvier & Valenciennes. Amber- 

 fish.

 Smith, 1898, p. 97; Kendall, 1908, p. 79. 



Woods Hole, Menemsha Bight; most frequent 

 at latter point, but never common. Edwards. 

 A specimen which had been so labeled in the 

 local collection is very doubtfully of this spe- 

 cies. Sumner.

Buzzards Bay, under the same circumstances as 

 5. zonata, but of rare occurrence. Only two 

 specimens recorded prior to 1898. Smith and 

 Kendall. One taken in 1905. Edwards. 

 Owing to the difficulty with which members 

 of this genus are distinguished from one an- 

 other, all records of occurrence must be ac- 

 cepted with caution. 



Parasites: Synbothrium filicolle (cysts). Lin- 

 ton.
