 HADDOCK 5 (Melanogrammus ceglifinus.} 



The haddock is not much unlike the cod in the character of its food. 

 It is, perhaps, still more omnivorous, or, at least, it generally contains a 

 greater variety of species of shells. &c. ; many of the shells that it 

 habitually feeds upon are burrowing species, and it probably roots 

 them out of the mud and sand. 



A complete list of the animals devoured by the haddock would 

 doubtless include nearly all the species belonging to this fauna. We have 

 had few opportunities for making observations on the food of the haddock 

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



A specimen taken at Wood s Hole, 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 : . c

The above list doubtless contains only a small portion of the species 

 collected by Mr. Trumbull, but they are all that are specially recorded.
