Kopeecon Point, at Phalarope station 66.* — 
Survey. 
Opercularella pumila Clarke. 
Hargitt, 1909, p. 375. 
A few specimens were dredged by the Survey 
in Vineyard Sound, off Naushon, in March, 
1908, which Dr. Hargitt regards as identical 
with Clarke’s species above named. This is 
the first record of occurrence since the original 
description. 
Calycella syringa (Linnaeus). 
Nutting, 1901, p. 355; Hargitt, 1909, p. 376. 
Found abundantly in the Woods Hole region, 
“growing over all sorts of plant-like marine 
organisms, especially other hydroids.” — Nut- 
ting. Seasonally abundant, according to 
Hargitt. “Rather uncommon during the mid- 
summer season,’’ and then apparently not 
reproducing sexually. In early spring, “it 
seems much more abundant and immense col- 
onies with prolific crops of gonangia are not 
rare.’’ Crab Ledge and off Sankaty Head. — 
Plargitt. Tarpaulin Cove, March, 1908. 
(Dredged by Sumner, identified by Hargitt.) 
Calycella nuttingi Hargitt. 
Hargitt, 1909, p. 378 (sp. nov.). 
Woods Hole; fishing grounds off Sankaty. A 
very minute species, found first upon Bugula 
turrita, and in general “found only associated 
with other hydroids, or similar organisms, e. g., 
Bryozoa.” 
Family AJquoreid^E. 
tStomobrachium tentaculatum Agassiz. 
Hargitt, 1904, p. 51; Mayer, 1910, p. 322. 
“I have occasionally taken at Woods Hole what 
may have been fragments of . . . this me- 
dusa. ’ ’ — Hargitt. 
Rhegmatodes tenuis Agassiz. 
L. Agassiz, 1862, p. 361; A. Agassiz, 1865, p. 95; 
Verrill and Smith, 1873, p. 729, 454; Nutting, 
1901, p. 383; Hargitt, 1902a, p. 553; 1904, p. 52; 
1908, p. 112; Mayer, 1910, p. 332 ( dEquorea 
tenuis). 
Recorded for local waters by a number of writers. 
The species is one of decidedly variable fre- 
quency, “occurring at very irregular periods, 
Rhegmatodes tenuis — Continued . 
and a very erratic manner.’’ At times it is 
abundant, while a number of years may elapse 
without its being observed at all. (See par- 
ticularly Hargitt, 1908.) 
Ova shed early in morning, August 15, 1893. — J. 
P. McMurrich, in Marine Biological labora- 
tory card catalogue. 
/. Equorea albida Agassiz. 
L. Agassiz, 1862, p. 359; A. Agassiz, 1865, p. no;

1901, p. 382; Hargitt, 1901b, p. 592; 1904, p, 
52; Mayer, 1910, p. 331. 
Recorded for local waters by A. Agassiz and by 
Hargitt. According to the latter author, this 
medusa is “not uncommon . . . during late 
summer and autumn.” 
Zygodactyla grcenlandica (Peron & Lesueur). 
A. Agassiz, 1865, p. 103; Verrill and Smith, 1873, 
p. 729, 449, etc.; Fewkes, 1881, p. 156; Nut- 
ting, 1901, p. 382; Hargitt, 1904, p. 52; Mayer, 
W 1 ®. p 335. 
Recorded for local waters by various observers, 
who report its occurrence from June to Sep- 
tember. Verrill refers to this species as com- 
mon, Hargitt as occasional. 
Family HalEciid^E. 
Halecium halecinum (Linn feus). [Chart 21.] 
Nutting, 1901, p. 357. 
“Abundant throughout the Woods Hole region, 
growing on shells, stones, etc., in shallow 
water.” — Nutting. Dredged by the survey 
with considerable frequency throughout the 
length of Vineyard Sound, and at scattered 
stations throughout Buzzards Bay; occurring 
in 3 to 16 fathoms, on quite various bottoms.
