BULLETIN OF THE BUREAU OP FISHERIES. 



Cordylophora lacustris Allman. 



Verrill and Smith, 1873, p. 734 (Cordylophora, 

 species undetermined); Nutting, 1901, p. 

 327; Hargitt, 1908, p. 99. 



" Found in a fresh-water pond near the [Nobska] 

 bathing beach by A. D. Morrill." Nutting. 

 Taken by Hargitt "in several similar ponds 

 in the region and near Falmouth, and in fresh 

 or brackish ponds on Marthas Vineyard." 

 Collected by Dr. Congdon at Tashmoo Pond, 

 Great Pond, and Weweantic River, and by 

 Mr. Edwards at Fresh Pond (Falmouth) and 

 Oyster Pond. 



"The reproductive season seems to be chiefly 

 in spring or early summer, and sparingly in 

 July. Colonies have been found later, Sep- 

 tember or October, but with no signs of gono- 

 phores." Hargitt. 



Family CORYNID^. 



Syncoryne inirabilis Agassiz.

 ilis); Fewkes, 1881, p. 141 (Sarsia mirabilis); 

 Bumpus, 1898, p. 487 (Coryne); Mead, 1898, 

 p. 704 (Coryne); Nutting, 1901, p. 328, 372;

 Hydroids on Bureau of Fisheries pier, at 

 Woods Hole. Bumpus, Mead. Waquoit. 

 Edwards, cited by Nutting. Rocks in Woods 

 Hole Passage. G. M. Gray. Medusae re- 

 ported locally by various observers. 



"Breeding hydroids" in March. Bumpus. 

 In April (1898), according to Mead, the 

 hydroids "occurred in colonies that could be 

 measured by the square yard;" these disin- 

 tegrated later. Dr. A. G. Mayer found the 

 medusa to be common in Woods Hole Harbor 

 on March 4 (1908); while Dr. Mead and Mr. 

 G. T. Hargitt report its occurrence during 

 April. According to Mr. Edwards 's towing 

 records it is commonest during April and May, 

 though taken occasionally in other months. 

 The seasonal range is stated by Dr. C. W. 

 Hargitt as extending from February to May. 



Syncoryne producta Hargitt. 



Hargitt, 19023, p. 550 (Coryne producla, sp. nov.); 



Hargitt, 1904, p. 30; Mayer, 1910, p. 63 (Sarsia 



kargilli). 

 Woods Hole: A single medusa taken in tow, 



August 10, 1901. 



?Corynitis agassizii McCrady. 



Bumpus, iSgSb, p. 857; Murbach, 1898, p. 354; 

 Nutting, 1901, p. 329, 372; Hargitt, 1904, p. 

 42; 1908, p. 100; Mayer, 1910, p. 72. 



Murbach reported the occurrence of "Corynitis 

 agassizii" upon floating sargassum from Vine- 

 yard Sound. Hargitt has shown, however, 

 that these observations refer to an entirely 

 different species, Gemmaria gemmosa McCrady, 

 which Murbach endeavored to identify with 

 Corynitis agassizii. Dr. Hargitt knows of no 

 authentic records of the occurrence of the 

 latter species at or near Woods Hole. The 

 reader is referred to the conflicting statements 

 of Hargitt, Murbach, and Mayer in the papers 

 cited. 



Family CLADOCORYNID^. 



Cladocoryne floccosa sargassensis Hargitt. 



Hargitt, 1909, p. 369 (var. nov.). 



A form thus designated by Dr. Hargitt was 

 taken on floating sargassum in Vineyard 

 Sound during the summer of 1907. 



Family CODONIID^;. 



Dipurena strangulata McCrady. 



L. Agassiz, 1862, p. 341 (Dipurena conica); 

 A. Agassiz,. 1865, p. 181 (Dipurena conica};

 rena conica); Fewkes, 1881, p. 155 (Dipurena

 strangulata}; 1904, p. 30 (D. strangulata, p. 

 31 (D. conica}; Mayer, 1910, p. 76 (Slabberia 

 strangulata).

 and vicinity, in midsummer, common. 

 Hargitt. 



J. P. McMurrich (in Marine Biological Labora- 

 tory card catalogue) records having obtained 

 ova on August 7 (1893). 



Of the "Dipurena conica" of A. Agassiz, Hargitt 

 writes: "It seems altogether probable . . . 

 that we have here simply a varietal form, 

 which would hardly justify specific separation, 

 and should probably be included under the 

 above species."
