A. Agassiz, 1865, p. 48; Verrill and Smith, 1873, 
p. 724, 449, etc.; Fewkes, 1881, p. 173; 1882, 
p. 293; Hargitt, 1904, p. 69; Mayer, 1910, p.

Common in local waters throughout the summer. 
Reported as early as May (Edwards), as late 
as October (Gray). 
Pelagia cyanella Peron & Lesueur. 
Hargitt, 1904, p. 70; Mayer, 1910, p. 574- 
“ Southward from Marthas Vineyard in the region 
of the Gulf Stream;” 2 specimens. Dr. Har- 
gitt believes this species should be retained in 
the local list. 
Class ACT1NOZOA. 
Family Alcyoniid^. 
Alcyonium carneum Agassiz. [Chart 24.] 
Verrill and Smith, 1873, p. 737, 497, etc.; Sum- 
ner, 1910, fig. 14. 
“Off Cuttyhunk Island, 10 to 15 fathoms; off 
Gay Head, 8to iofathoms.” — Verrill. Western 
end of Vineyard Sound and mouth of Buzzards 
Bay; Crab Ledge; dredged in 7 to 19 fathoms, 
most commonly on gravelly or stony bottoms. — 
Survey. 
Fish Hawk stations: 7572 (many pieces), 7582 
(1 piece), 7587 (few small pieces), 7588 (2 small 
pieces), 7595 (few pieces), 7603 (few small 
pieces)t, 7605 (1 small piece), 7606 (1 piece)!, 
7670 (1 clump), 7689 (few pieces), 7690, 7704 
(1 large clump), 7718 (1 clump), 7719 (1 clump), 
7721 (considerable quantities). Supplement- 
ary station (1909): 7670.

Family GoRGONiiDiE. 
? 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 CerianthidaJ. 
Cerianthus 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, who has examined 
specimens taken locally, informs us that they 
are to be assigned to the species here named. 
Family Zoanthid^E. 
Epizoantkus americanus Verrill. 
Verrill and Smith, 1873, p. 740, 510. 
Deeper waters off shore. Dredged by the Fish 
Hawk south of Marthas Vineyard in 28 and 29 
fathoms. Not taken in the Sound or Bay, and 
not strictly to be included in tire fauna of this 
region. Commonly found upon the shells of 
hermit crabs, though Verrill records its occur- 
rence on rocks. 
Family Edwardsiidaj. 
Edwardsia elegans 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. 
Edwardsia farinacea 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 adjacenf waters, of very varia- 
ble abundance. The young is parasitic in 
the ctenophbre, 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 very 
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.
