BIOLOGICAL SURVEY OF WOODS HOLE AND VICINITY. 



577 



Edwardsia lineata Verrill. 



Verrill and Smith, 1873, p. 739, 497, etc. (sp. 

 nov.). 



"Vineyard Sound and off Gay Head, 6 to 12 

 fathoms, among ascidians, annelid tubes, etc., 

 abundant." Verrill. This species at present 

 is certainly not generally distributed nor very 

 common in local waters. It has not been re- 

 corded from the survey dredgings. 



Family ILYANTHID^. 



Eloactis producta (Stimpson). 



Verrill and Smith, 1873, p. 738, 330, etc. (Halo- 



campa producta). 



Naushon; Marthas Vineyard; Nantucket. Ver- 

 rill. Katama Bay (" North Pond"), abundant 

 August 14, 1906. Osburn. West Falmouth, 

 North Falmouth, Hadley Harbor, Kettle 

 Cove. G. M. Gray. Muskeget Island. This 

 is a burrowing species, which conceals itself 

 in gravel or sand, only the distal end pro- 

 truding from the surface. 



Family ANTHEID^. 



Anemonia sargasscnsis Hargitt. 



Hargitt, 1908, p. 117 (sp. nov.). 



Vineyard Sound on floating sargassum. Re- 

 corded on October 15 and 16, 1905, and August 

 30, 1906. From its abundance on some of 

 these dates, it seems likely that the species 

 may have been present on many others. 



Family SAGARTIID^E. 



Cylista kucolena (Verrill). 



Verrill and Smith, 1873, p. 738, 329, etc. (Sa- 



gartia leucolena). 

 Buzzards Bay and Vineyard Sound. Verrill. 



Vineyard Haven at New York Yacht Club pier; 



Nobska Point,* on rocks, below low water. 



A common species, having a littoral habitat. 



Sagartia lucice Verrill. 



Verrill, 1898, p. 493 (sp. nov.); Parker, 1902, 

 p. 491. 



This species is now the most abundant actinian 

 of the region and is of general occurrence lit- 

 torally, growing on stones, living mussels, 

 rock-weed, etc., often in great profusion. It 

 is, however, a very recent immigrant, having 

 been first observed at Woods Hole by W. R. 

 Coe in 1898. S. luciaz was noticed for the 



Sagartia luciae Continued. 



first time by Prof. Ycrrill at New Haven in 

 1892, and is believed by him to have been 

 introduced into that region upon oysters, 

 which are annually brought from the South 

 and planted in Long Island Sound. According 

 to Parker, the species migrated eastward from 

 New Haven and northward to Salem, Mass., 

 within a period of 10 years. 



Sagartia modesta Verrill. 



Verrill and Smith, 1873, p. 738, 330, etc. 



"Naushon Island; low water, buried in sand or 

 gravel." Verrill. Local bathing beach, on 

 Buzzards Bay, between tides or at low water. 



Hargitt. 



An uncommon species locally. 



Metridium. dianthus (Ellis). [Chart 25.] 



Verrill and Smith, 1873, p. 738, 329 (.17. mar- 

 ginatum); Mead, 1898, p. jo^(M.tnarginatum). 

 As a littoral species, common and widely dis- 

 tributed in local waters, occurring on stones, 

 piles, etc., at or below low- water mark. 

 Dredged by the Survey at scattered stations 

 throughout the length of Vineyard Sound; sev- 

 eral stations at Crab Ledge; none in Buzzards 

 Bay; 4 to 25 fathoms, on mud-free bottoms. 

 Fish Hawk stations: 7521 bis (i), 7526 (i), 7532 

 (*). 7544 (i), 755 8 (i). 756o (2 large), 7565 (i), 

 757 2 (2), 7588 (2), 7595 (i), 7603 (several small), 

 7605 (3 large), 7606, 7608 (6 large), 7609 (i 

 small), 7693 (3), 7721 (very many), 7725, 7742 



(0. 7743 (*) 

 Phalarope station: 77 (i). 



The reproductive period of this anemone appears 

 to occur during the summer. Dr. Mead notes 

 that Metridium "was found to be full of eggs, 

 apparently nearly mature," on April 18 (1898), 

 while Dr. F. R. Lillie (Marine Biological Lab- 

 oratory card catalogue) records the presence of 

 ova and sperm on June 20 (1889). 



Family 



Tealia crassicornis (Miiller). 



Crab Ledge. Hargitt. Vineyard Sound? 

 Sumner. A specimen, believed to be of this 

 species, from the last-mentioned place, was 

 taken in the vicinity of Gay Head by the 

 Fish Hawk in August, 1907. Unfortunately it 

 was devoured by hermit crabs before it could 

 be carefully examined.
