70 REPORT OF COMMISSIONERS OF INLAND FISHERIES. 



during the winter in upper Narragansett Bay, and in summer in the 

 Wickford region and in Charlestown Pond, a brackish inlet from the 

 ocean. 



A special examination was made of the common mollusks to find 

 whether they were inhabited by copepods. The mussels and scallops 

 yielded negative results, but the common clam (Mya arenaria) was 

 found to be almost invariably the host of a new copepod which 

 occurred also in the quahog {Venus mercenaria) and in the sea clam 

 (Madra solidissima) . It had been hoped to secure a large number 

 of the forms parasitic on fish, but diligent search throught the 

 summer discovered only a few species, the fish in Narragansett Bay 

 being apparently unusually free from parasitic copepods. Our 

 thanks are here due to Mr, Henry C. Tracy for specimens of a number 

 of parasitic forms. 



The species starred in the list are recorded from Rhode Island for 

 the first time.
