 Cancer irroratus ; Pinnixa cylindrica ; Crangon vulgaris ^ squids, Xo%o

 narachnkis parma. 



Winter Flounder; {Pseudopleuronectes Americanus.) 



A specimen caught at Wood's Hole, in August, contained large num- 

 bers of Bulla soUtaria. 



Spotted Flounder -, (Lo;pliopsetta maculata.) 



I^umerous specimens caught in seines at Great Egg Harbor, April, 

 1871, contained large quantities of shrimp, especially Mysis Americana 

 and Crangon vulgaris; the liTSiwn, Falwmonetes vulgaris ; numerous Am- 

 phipods, Gammarus mucronatus ; one contained a Oehia affinis. 



Minnow ; (Fundulus ])isculentus.) 



Specimens caught in July, at Wood's Hole, contained large numbers 

 of Melam][)us hidentatus^ unmixed with other food. 



Sea-Herrino; {Clupea elongata.) 



Specimens taken in Vineyard Sound, May 20, contained several 

 shrimp, Crangon vulgaris^ about 1.5 inches long ; Mysis Americana., and 

 large numbers of an Amphipod, Gammarus natator ; also small fishes. 



Shad; [Alosa tyr annus.) 



Several specimens taken in the seines, at Great Egg Harbor, April, 



1871, contained finely- divided fragments of numerous Crustacea, among 

 which were shrimp, Mysis Americana. 



Several from the mouth of the Connecticut Eiver, May, 1872, contained 

 fragments of small Crustacea, (Mysis, &c.)

 Several specimens taken in the seines at Great Egg Harbor, April^ 



1872, contained large quantities of fragmentary Crustacea; one con- 

 tained recognizable fragments of shrimp, Crangon vulgaris. 



Menhaden ; [Brevoortia menhaden.) 



A large number of specimens freshly caught in seines at Great Egg

 stomachs filled with large quantities of darh mud. They undoubtedly 

 swallow this mud for the sake of the microscopic animal and vegetable 

 organisms that it contains. Their complicated and capacious digestive 

 apparatus seems well adapted for this crude and bulky food.
