Distribution. — San Dieg,o, Cal. (Torrey). 



CLYTIA JOHNSTONI (Alder) 

 Campanularia johnstoni Alder, Trans. Tynes. F. C, 1857, p. 36. 

 Clytia johnstoni Clark, Alaskan Hydroids, 1876, p. 212. 

 Campanularia johnstoni Calkins, Some Hydroids of Puget Sound, 1899, 

 p. 348. 



Chjtia hicophora Torrey, Hydroida of the Pacific Coast, 1902, p. 1. 



Distribution. — Port Etches, Alaska (Clark) ; Puget Sound 

 (Calkins) ; Oakland Creek, Cal. (Torrey). 



Both Clark and Calkins, in reporting this species, do so with 

 doubt as to their identification. Clark's figures would serve very 

 well for one of the varieties of Campanularia urceolata, and 

 Calkins' are not unlike the unbranched forms of Clytia edwardsi.^ 

 Torrey 's reference to it is very meagre, as it occurs only in a 

 foot-note. 



CLYTIA UNIVERSITATIS Torrey 



Campanularia denticulata Torrey, Hydroida of the Pacific Coast, 1902,. 

 p. 51. 



Clytia universitatis Torrey, Hydroids of San Diego, 1904, p. 19. 



Distribution. — San Diego, San Pedro, Cal. (Torrey). 

 Genus EUCOPELLA 



Trophosome. — Stem unbranched arising, from an anastomosing^ 

 stolon ; hydrothec£e with very thick walls and smooth margins. 



Gonosome. — Gonophores produce large medusoid structures, 

 never more than two, one large and one very small in a gonangi- 

 um at the same time. They are of an elongated dome shape. 

 They differ from ordinary medusee in not being provided with 

 mouth or digestive cavity. 



EUCOPELLA CALICULATA (Hincks) 

 Campanularia caUculata Hincks, Ann. and Mag. N. H., 3rd Ser. XI, 1863, 



p. 178. 



Campanularia caUculata Calkins, Some Hydroids of Puget Sound, 1899, 



p. 351. 



Clytia caUculata Nutting, Hydroids of the Harriman Ex. 1901, p. 170. 



Distribution. — Pt. Wilson, Pt. Townshend, Bremerton (Calk- 

 ins) ; Yakutat, Alaska (Nutting) ; San Juan Archipelago. 



Specimens of this species show very well the typical Eucopella 

 gonosome, but as these gonosomes have been figured by Calkins- 

 to bring out the features in an excellent manner, it is not neces- 

 sary to refer to them further.
