Microgadus tomcodus Gill. Tomcod; Frost-fish. 
Several specimens from New Haven Harbor, January 30, contained 
numerous Amphipods, among which were Mera levis; Gammarus, sp.; 
Ampelisca, sp.; an undetermined Macrouran; numerous Entomostraca; 
the larva of Chironomus oceanicus. 
A lot taken in a small pond at Woed’s Holl, in March, by Mr. Vinal 
N. Edwards, contained the common Shrimp, Crangon vulgaris ; large 
numbers of the green Shrimp, Virbius zostericola ; the Prawn, Palemo- 
netes vulgaris; large quantities of Amphipods, especially of Gammarus 
annulatus, G. natator, Calliopius leviuscula, and Microdeutopus minax ; 
and smaller numbers of Gammarus ornatus and G. mucronatus. 
Another lot of twelve, taken in April at the same place, contained 
most of the above, and in addition several other Amphipods, viz: Mera 
levis, Pontogeneia inermis, Ptilocheirus pinguis, and Caprella ; also Nereis 
virens, and various small fishes. 
Melanogrammus eglifinus Gill. Haddock.

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 doubt- 
less include nearly all the species belonging to this fauna. We have
