Hargitt, 1904, p. 70; Mayer, 1910, p. 574.

 the local list.

Family GORGONIID^. 



? Pterogorgia gracilis Verrill. 



A fragment of a gorgonid believed at the time 

 to have been taken in Vineyard Sound at Fish 

 Hawk station 7568 has been assigned to this 

 species by Prof. Nutting. It seems very prob- 

 able that the specimen came from waters far 

 beyond the limits of the region, having, per- 

 haps, become entangled in the meshes of the 

 dredge net during some earlier collecting trip. 



Family CERIANTHID^. 



Cerianthas americanus Verrill. 



Mr. G. M. Gray reports the rare occurrence of a 

 Cerianthus in the Eel Pond, just inside the 

 outlet; also just outside the latter; once at 

 Ram Island. Dr. Hargitt, Avho has examined 

 specimens taken locally, informs us that they 

 are to be assigned to the species here named. 



Family ZOANTHID,E. 



Epizoanthus americanus Verrill. 



Verrill and Smith, 1873, p. 740, 510. 



Deeper waters off shore. Dredged by the Fish 

 Hawk scmth of Marthas Vineyard in 28 and 29 

 fathoms. Not taken in the Sound or Bay, and 

 not strictly to be included in the fauna of this 

 region. Commonly found upon the shells of 

 hermit crabs, though Verrill records its occur- 

 rence on rocks. 



Family EDWARDSIID^E. 



Ed-wardsia ekgans Verrill. 



West Falmouth. Hargitt. Ram Island. Gray. 

 According to Mr. Gray, this anemone is fairly 

 common in suitable localities, living in the 

 sand at the roots of eelgrass, where it may be 

 taken by digging. 

 Ediiurdsiafarinacea Verrill. 



Verrill and Smith, 1873, p. 739, 451. 



" On the soft muddy bottom off Gay Head, in 19 

 fathoms, " one specimen. 



Edwardsia leidyi Verrill. 



A. Agassiz, 1865, p. 23 (here mentioned as an 

 unknown "worm"); Verrill and Smith, 1873, 

 p. 457 (citing Agassiz) Verrill, 1898 (sp. nov.). 

 Woods Hole and adjacent waters, of very varia- 

 ble abundance. The young is parasitic in 

 the ctenophore, Mnemiopsis leidyi; it is 

 believed by Verrill and others that the animal 

 becomes free living in later life, but its history 

 is not known at present. On November 13, 

 1907, the ctenophores, with their contained 

 parasites, were so numerous in Buzzards Bay 

 that the latter organisms were at times vary 

 conspicuous as one looked down from the 

 deck of the Phalarope. Sumner. On the 

 other hand, the Edwardsia is not always com- 

 mon when Mnemiopsis is present in abundance.
