38 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



had few opportunities for makiug observations on the food of the bad- 

 dock south of Cape Cod, hut have examined many from farther north. 



A specimen taken at Wood's Holl, November G, 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 ofmoUusls obtained from stomachs of haddock, at Stonington, Conn., 

 by Mr. J. H. Trumbull. 



Neptunea pygmsea (Fusus Trumbulli). 



Astyris zonalis (Buccinum zonale). 



Bulbus flavus (?) (Natica flava). 



Margarita obscura. 



Actaeon punctostriata (Tornatella punctostriata). 



Cylichna alba (Bulla triticea). 



Serripes Groenlandicus (?) (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 Massachusetts Bay, 

 September, 1871. 



GASTROPODS. 



ISTatica clausa. 

 Margarita Groenlandica. 



LAMELLIBRANCHS. 



Leda tenuisulcata. 

 Nucula proxima. 

 Nucula tenuis. 

 Crenella glandula. 



ECHINODERMS. 



Psolus phantapus. ' 

 Lophothuria Fabricii. 



In addition to these there were fragments of shrimp, probably Panda- 

 Ins 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.
