BULLETIN OF THE BUREAU OF FISHERIES 
Lookdown, Selene vomer (Linnaeus) 
During the autumn of 1933 many small lookdowns were reported from traps at 
the mouth of Casco Bay, one also from Beverly Farms, and another from North 
Truro, an unusual incursion, for only three specimens had previously been recorded 
in the Gulf of Maine. Jones (1882 p. 89) and Honeyman (1886 p. 328) record this 
species (young) as occasional in the shore waters of Nova Scotia, presumably\long 
the east coast. 
Leatherjacket, Oligoplites saurus (Bloch and Schneider) 
A specimen taken in a trap off the outer beach at Chatham is the only record 
for the Gulf of Maine. 
Bluefish, Pomatomus saltatrix (Linnaeus) 
For many years no bluefish had been reported north of Cape Ann, until 1925, 
when one was caught off Halifax, Nova Scotia. This seems to have presaged a tempo- 
rary extension of range, for numbers of them visited the inner coasts of the gulf 
northward to Casco Bay in the summer of 1927, while in 1930 the bluefish was again 
reported at Halifax (two specimens) and at Port Mouton, Nova Scotia (one specimen, 
Leim, 1930, p. xlvi). 
Common dolphin, Coryphatna hippurus Linnaeus 
A dolphin about 3 % feet long taken 60 miles south-southwest, of Cape Sable, in 
the deep gully between Browns and Georges Banks by the trawler Natalie Hammond, 
August 15, 1930, is the first Gulf of Maine record. The specimen is now in the 
collection of the Boston Society of Natural History. 
Opah, Lampris regius (Bonnaterre) 8 
A specimen about 3 feet long was taken in July 1925, on Western Bank, southwest 
of Sable Island, by the schooner Falmouth (Radcliffe, 1926), while another of about 
the same size stranded on the beach at Hyannis, Mass., on September 17, 1928. 
Johnson’s sea bream, Taractes princeps Johnson 
A fish taken on Browns Bank, off Cape Sable in January 1928 is the first record 
of this species for the western Atlantic. This bream previously was known only 
from Madeira, in the eastern Atlantic. For a detailed account and comparison with 
allied species see Bigelow and Schroeder (1929). 
Butterfish, Poronotus triacanthus (Peck) 
Recent records show that the northward range of this species extends to the east 
coast of Newfoundland, as well as to Nova Scotia as has long been known. 
It now seems well established that the butterfish actually withdraw from the 
gulf when they disappear in the autumn, as they do from the immediate shore waters 
farther south, and from inland waters such as Chesapeake Bay. Until very recently 
the winter home of the butterfish was unknown; but as they are now often taken in 
the winter otter trawl fishery recently established off the coast between Chesapeake 
s This species was given as Lampris luva (Gmelin) by Bigelow and Welsh (1925, p. 242)i
