Obelia gelatinosa (Pallas). 



Verrill and Smith, 1873, p. 728, 391, etc.; 

 Nutting, 1901, pp. 351, 380; Hargitt, 1904, 

 p. 48; Mayer, 1910, p. 244. 



Listed by Nutting and Hargitt for the region. 

 According to Verrill, this species is sometimes 

 found in waters which are quite brackish, 

 while Nutting states that it may grow between 

 tides. 



Obelia pyriformis (A. Agassiz). 



Verrill and Smith, 1873, p. 727, 390, etc.; 

 Hargitt, 1904, p. 49; Mayer, 1910, p. 247. 



"Very abundant on piles of wharves, etc., at 

 Woods Hole." Verrill. Hargitt records the 

 medusae locally. Nutting thinks it likely that 

 this species is identical with Obelia dichotoma 

 (Linnaeus). 



Obelia bicuspidata Clarke. 



Nutting, 1901, p. 351; Mayer, 1910, p. 254 (Obelia 

 bidentata). 



"Near Woods Hole, 19 fathoms." Nutting. 

 Vineyard Haven. Hargitt. 



Obelia longissima (Pallas). 



Verrill and Smith, 1873, p. 728; Nutting, 1901, 



P- 35 1 . 379; Mayer, 1910, p. 255. 

 Gay Head. Verrill. Woods Hole. Nutting. 



Obelia bidentata Clarke. 



Nutting, 1901, p. 351 (not recorded locally); 

 Mayer, 1910, p. 254. 



Vineyard Haven. Hargitt. 



Obelia congdoni Hargitt. 

 Hargitt, 1909, p. 375 (sp. nov.) 



Vicinity of Woods Hole, on floating sargassum, 

 taken during the summers of 1907 and 1908. 



"Obelia polygena Verrill" (said to be equivalent 

 to Eucope polygena A. Agassiz) and "Obelia 

 di-varicata Verrill" (=Laomedea divaricata 

 McCrady) are likewise listed by Verrill and 

 Smith (1873, p. 727), the former species being 

 . recorded as taken "off Gay Head, 4 to 5 fath- 

 oms, not common," the latter "found on float- 

 ing algae in Vineyard Sound." The identity 

 of the species here referred to is not certain. 

 Obelia sp. undet. 



Unidentified specimens belonging to this genus, 

 but probably referable to one or more of the 

 above species, are recorded for Fish Hawk sta- 

 tion 7676 and Blue Wing stations 21 and 23. 

 Gonothyrcea loveni Allman. 



Nutting, 1901, p. 352; Hargitt, 19013, p. 386. 

 Woods Hole, "on fucus and other algae, rocks, 

 etc.;" taken off Nantucket in June, 1906, by 

 Mr. Edwards. Hargitt. 



Family LAFGEID^. 



Lafcca dumosa Fleming. 



Nutting, 1901, p. 355. 



Nantucket Shoals, growing on other hydroids. 



Verrill, cited by Nutting. 

 Lafosa gracillima (Alder). 



Nutting, 1901, p. 356; Hargitt, 1908, p. 113. 



"Although not specifically reported from the 

 Woods Hole region, it doubtless occurs there, 

 as its distribution is much like that of L. 

 dumosa."- Nutting. Prof. Hargitt found 

 specimens which he thinks were probably 

 referable to this species upon a shell dredged 

 off Sankaty Light at a depth of 25 fathoms. 



Hebella pygmaa Hincks. 

 Nutting, 1901, p. 353. 

 "Found on a polyzoon off Nantucket; Sankaty 



Light, east by south; depth, 24 fathoms (Vinal 



Edwards)." 



Hebella sp. undet. 



A minute species taken at Crab Ledge. Hargitt. 



Family HYDROCERAIINID/E. 



Kcraiosum complexum Hargitt. 



Hargitt, 1909, p. 379 (sp. nov.); Hargitt, 1911, 

 p. 187. 



Crab Ledge, summers of 1903 and 1909. Super- 

 ficially, this species bears considerable resem- 

 blance to a branching sponge , and was at first 

 regarded as such. All of the specimens which 

 have been examined by Dr. Hargitt appear 

 to be in a state of degeneration, perhaps of 

 aestivation, "no hydranths or similar organs 

 being distinguishable."
