narrower than is shewn in Hincks' figure. It may be 

 regarded as a small variety of the species. 



Possibly this is the species mentioned by Byerley under 

 the name of Campanularia volubilis. 



Obelia geniculata, Linnaeus. 



Kecorded by Byerley under the name of Laomedea geni- 

 culata, as being very abundant upon Algse, dead shells, &c. 

 Mersey (J. S. Hicks). 



Obelia gelatinosa, Pallas. 



Kecorded by Byerley under the name of Laomedea 

 gelatinosa, as being common. Found in Hilbre Swash on 

 July 2nd, 1872, by Mr. A. 0. Walker. Liverpool (Colling- 

 wood). Menai Straits (Pennington). 



This species is recorded by Hincks as being very common 

 on the Dingle rocks, Egremont, Hilbre Island, and other 

 places near Liverpool, in 1868. Mersey (J. S. Hicks). 



One colony of this species, about 2 J inches in height, was 

 obtained at the south end of the Isle of Man, August, 1885. 

 This colony differs from Hincks' figure and description 

 in having the margins of the hydrothecae distinctly not 

 denticulated. The hydrothecas are very thin, and the edges 

 are slightly ragged in some cases, but never denticulated. 

 In all other respects the zoophyte agrees with Hincks' 

 description. 



Obelia longissima, Pallas. 



Laomedea dichotoma, var. ^3, B. Z. p. 102. 



Found off the Little Ormes Head on June 22nd, 1880, by 

 Mr. A. 0. Walker. Recorded from Blackpool by Pennington. 



Obelia flabellata, Hincks. 



Campanulai'ia fiabellata, Hincks, Ann. N. H. ('3rd series), xviii, 

 297. 



Not previously recorded from this neighbourhood.
