38 REPORT OF COMMISSIONER OF FISH AND FISHERIES. d 
had few opportunities for making observations on the food of the had- 
dock south of Cape Cod, but have examined many from farther north. — 
A specimen taken at Wood’s Holl, November 6, 1872, contained a 
large quantity of Gammarus natator and a few specimens of Crangon 
vulgaris. Another from Nantucket contained the same species. 
The following species of shells were mentioned by Mr. Linsley, in his 
catalogue, as from the haddock: 
List of mollusks obtained from stomachs of haddock, at Stonington, Conn., 
by Mr. J. H. Trumbull, ° 
Neptunea pygmea (Fusus Trumpulli). 
Astyris zonalis (Buccinum zonale). 
Bulbus flavus (?} (Natica flava). 
Margarita obscura. 
Acton puncto-striata (Tornatella puncto-striata). 
Cylichna alba (Bulla triticea). 
Serripes Greenlandicus (?) (Cardium Groenlandicum). 
The above list doubtless contains only a small portion of the species 
collected by Mr. Trumbull, but they are all that are specially recorded. 
As an illustration of the character and diversity of the haddock’s food, 
I add a list of the species taken from the stomach of a single specimen, 
from the Boston market, and doubtless caught in Massachussetts Bay, 
September, 1871. : ;

In addition to these there were fragments of shrimp, probably Panda- 
lus annulicornis, and numerous Annelids, too much digested for identi-— 
fication. 
Pollachius carbonarius Bon. Pollock. 
A species of Thysanapoda and one or two species of Mysis serve as 
food for the pollock about Eastport, Me. These crustaceans go under 
the general name of “‘ shrimp” among the fishermen, and swim together 
in large schools. <A. E. Verrill, 1871.
