 demonstrated by actual observation.

 Survey. Hydroid phase chiefly on the 

 shells of hermit crabs. Medusae fairly com- 

 mon locally.

 Murbach. 



Hydractinia echinata Fleming. [Chart 15.] 



A. Agassiz, 1865, p. 198 (Hydractinia polyclina);

Generally present in local waters; distribution 

 in large degree coextensive with that of the 

 hermit crabs, on whose shells it dwells, though 

 this species appears to be nearly or quite 

 lacking in the central portions of Buzzards 

 Bay. Recorded from all of the Crab Ledge 

 stations. Dredged on every sort of bottom. 

 In the great majority of cases Hydractinia is 

 found upon shells occupied by hermit crabs, 

 though its presence has been noted in the fol- 

 lowing situations by various local observers: 

 rocks (Verrill); rock-weed and Limulus 

 (Bumpus); piles of piers (Nutting, Osburn, 

 Hargitt); maxillipeds of lobster, chela of 



distinct from the H. echinata of Europe. Leidy, McCrady and
