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. 

 Hargitt. Tarpaulin Cove, March, 1908. 

 (Dredged by Summer, 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 ^QUOREID^E. 



tSlomobrachium tentaculatum Agassiz.

 may have been fragments of ... this me-

 tennis). 



Recorded for local waters by a number of writers. 

 The species is one of decidedly variable fre- 

 quency, "occurring at very irregular periods, 



Rhegmatodes tennis 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.)

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).

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 (Linnaeus). [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 1 6 fathoms, on quite various bottoms.
