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-

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.

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. 
Taken by dip net, pound, and seine. 
Food: Menidia gracilis. — Smith. Fish (probably 
butterfish) . — Linton . 
Parasites (Linton): Nematodes — Ascaris incurva. 
Cestodes — Tetrarhynchus bisulcatus (cysts). 
Seriola lalandi Cuvier & Valenciennes. Amber- 
fish. 
Jordan and Evermann, 1896, p. 903; H. M. 
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. 
Parasites (Linton): Nematodes — Ascaris incurva. 
Cestodes — Dibothrium sp. (larvae), Rhyncho- 
bothrium sp. (cysts). Trematodes — Distomum

Buzzards Bay, under the same circumstances as 
S. 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.
