Cylichna alba (Brown). 
Gould 1870, p. 220; Verrill and Smith, 1873, p. 
663, 508, etc. (In neither work listed for this 
region). 
Dredged by the survey near the lower end of 
Buzzards Bay, at Fish Hawk stations 7657 (1 
shell), and 7661 (2 shells); 9 to 13 fathoms, 
mud. (Identified by R. C. Osbum.) 
Family BulliM. 
Hamine'a solitaria Say.

Smith, 1873, p. 662, 371, etc. ( Bulla solitaria ); 
Dali, 1889, p. 88. 
New Bedford. — Gould. “Gammon, in the 
muddy lagoons and salt-ponds along the shores 
of Vineyard Sound, Buzzards Bay. . . . 
Abundant in a small pond near Holmes 
Hole. ” — Verrill. Eel Pond, Hadley Harbor. — 
G. M. Gray. Katama Bay at several points. — 
Osbum. This species is doubtless of pretty 
general distribution in such localities as those 
mentioned but, being of strictly littoral habi- 
tat, it was only recorded three times during 
the survey dredging, viz, at Phalarope sta- 
tions 127 (shells common), 161 (few shells), and 
166 (1 living). 
Eggs laid in large jelly-like balls, which are fas- 
tened by stalks to the sand; deposited August 
20 or earlier.— E- G. Conklin, Marine Biologi- 
cal Laboratory card catalogue. 
“ Devoured in large numbers by the flounders 
and doubtless by other fishes.”— Verrill. 
Family Aplysiid^E. 
Tethys willcoxi (Heilprin) var. 
Dali, 1889, p. 90 ( Aplysia willcoxi). 
Katama Bay, October 31, 1900, 1 large specimen* 
(sent by Mr. Fisher of Edgartown to Mr. Ed- 
wards). Buzzards Bay, near Woods Hole, 
October 11, 1906, 1 specimen (probably of 
this species) taken in a lobster-pot. During 
October, 1910, this mollusk was taken rather 
frequently throughout the waters of the region, 
one or more specimens being recorded from 
New Bedford, Westport, Buzzards Bay (near 
Woods Hole), Lamberts Cove, Tarpaulin Cove, 
Robinsons Hole, and Menemsha Bight. One of 
these specimens was referred to Dr. Dali for 
. identification 
Family PeEurobranchid.*®. 
? Pleurobrancheea tarda Verrill. 
Verrill, 1882c, p. 546. 
Off Marthas Vineyard in 28 fathoms, 1881 (thus 
not strictly within the limits of the region). — 
Verrill. Four specimens, presumably from 
the vicinity of Woods Hole, though not la- 
beled, were assigned to this species by Dr. 
MacFarland. It is quite possible, however, 
that these were likewise taken beyond the 
limits of the region. 
Family Dendronotid.®. 
Dendronotus arboresc'ens (Muller). 
Gould, 1870, p. 234; Verrill and Smith, 1873, P- 
665, 495. etc. 
“Rare and local south of Massachusetts Bay.” — - 
Verrill. Not yet recorded for this region, 
though the latter lies within the stated range 
of the species. 
Dendronotus robustus Verrill. 
Verrill, 1879, p. 197; 1882c, p. 550. 
Vineyard Sound. — Verrill. Six specimens from 
the vicinity of Woods Hole f (collected by 
G. M. Gray). 
Family vScvleaud/E. 
Scyllcea pelagica Linnaeus. 
Verrill, 1878, p. 211. (Scyllcea edwardsii)-, 1882c, 
p. 550 (Scyllcea edwardsii). 
Little Harbor, Woods Hole, on eel grass; also in 
the Sound on sargassum; first reported in the 
autumn of 1877. — Verrill. Specimens which 
are probably of this species have been taken 
among floating sargassum in Vineyard Sound, 
on the following dates, often in great numbers: 
August 20, 22, 28*, and September 5, 1906. 
Some were collected likewise during the pre- 
ceding summer and probably at other times. 
Dr. MacFarland comments: “A careful ana- 
tomical study of the Woods Hole specimens 
must be made before their identity with .S'. 
pelagica L. can be positively determined.” 
Family PoLYCERim®. 
Polycerella emertoni Verrill. 
Verrill, 1880c, p. 387 (sp. nov.); 1882c, p. 548. 
Woods Hole Harbor, August and September, 1875 
and 1881, on eel grass and hydroids; Newport, 
on piles. 
Eggs laid in confinement, July 24. — Verrill.
