INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 517 



j tired. 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 OjpMopholis 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 made, 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. 

 xlviii, p. 271, 1845. In that list a large number of species are particularly 

 mentioned as from the stomachs of cod and haddock, at Stouington, 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:
