jured. They are also very fond of shrimps. and of crabs, which they 
frequently swallow whole, even when of large size. The brittle star- 
fishes (Ophiurans) are also much relished by them. I have taken large 
masses of the Ophiopholis aculeata from their stomachs on the coasts of 
Maine and Labrador; and in some cases the stomach would be distended * 
with this one kind, unmixed with any other food. 
In this region I have not been able to make any new observations on 
the food of the cod. This deficiency is partially supplied, however, by 
the observations made by me on the coast of Maine, &c., coupled with 
the very numerous observations made at Stonington, Connecticut, 
many years ago, by Mr. J. H. Trumbull, who examined large numbers of 
the stomachs of cod and haddock, caught within a few miles of that 
place, for the sake of the rare shells that they contained. This collec- 
tion of shells, thus wade, was put into the hands of the Rev. J. H. Lins- 
ley, who incorporated the results into his ‘- Catalogue of the Shells of 
Connecticut,” which was published after his death, and in a somewhat 
unfinished state, in the American Journal of Science, Series I, vol. 
xlvili, p. 271, 1845. In that list a large number of species are particularly 
mentioned as from the stomachs of cod and haddock, at Stonington, all 
of which were collected by Mr. Trumbull, as he has informed me, from 
fishes caught on the fishing-grounds near by, on the reefs off Watch 
Hill, &c. Many other northern shells, recorded by Mr. Linsley as from 
Stonington, but without particulars, were doubtless also taken from 
the fish-stomachs by Mr. Trumbull. There was no record made of the 
Crustacea, \c., found by him at the same time. 
The following list includes the species mentioned by Mr. Linsley as 
from the cod. For greater convenience the original names given by him 
are added in parentheses, when differing from those used in this report:
