Several specimens from New Haven Harbor, January 30, contained 

 numerous Ampliipods, among which were Mcera levis; Gammarus, sp.; 

 Ampelisca, sp.; an undetermined Macrouran; numerous Entomostraca; 

 the larva of Chironomus oceanicus. 



A lot taken in a small pond at Wood's Holl, in March, by Mr. Vinal 

 N. Edwards, contained the common Shrimp, Crangon vulgaris; large 

 numbers of the green Shrimp, Yirbius zostcricola ; the Prawn, Palcvmo-

 levis, Pontogeneia inermis, Ptilocheirus pinguis, and Gaprella; also Nereis 

 virens, and various small fishes.
