the base of the hydrothecae, fewer at the base of the pedicels and in 

 some cases 3-5 towards the centre; hydrothecae very long, tapering 

 very gradually from margin to base; the 9-10 teeth are deeply cut 

 and each is provided with two distinct cusps. 



Gonosome. — Unknown. 



Distribution. — Nanoose Bay, Departure Bay, east of Protection 

 I., near Round I. in Dodds Narrows, Whaleboat Passage. 



The margin of the hydrotheca in this species resembles that of 

 C. gelatinosa but the hydrothecae are much longer, absolutely and 

 relatively to the width than in that species. In its simple unbranched 

 stem it goes to the other extreme to the fascicled and much branched 

 stem of C. gelatinosa. The hydrotheca also resembles that of Cam- 

 panularia neglecta Alder, but the cusps on the teeth are much more 

 distinct on account of the incision between the cusps being deeper. 

 The cusps are blunter than in C. neglecta. Clytia longicyatha (Allman) 

 has a longer hydrotheca but the ratio to its greatest width is not so 

 great as for this species. 



As the gonosome has not been found the species can be put in 

 the genus Campanularia provisionally.

Trophosome. — Stems unbranched serving for the pedicels of the 

 hydranths, arising from a stolon which at this point has a distinct 

 elevation, somewhat bulbous in appearance; pedicel annulated at 

 the base and below the hydrotheca and sometimes more or less through- 

 out; hydrotheca long and narrow, tapering- but slightly from margin 

 to base; teeth usually 5 in number, deep and rounded at the tip. 



Gonosome. — Unknown, 



Distribution. — Departure Bay, Queen Charlotte Is. (Fraser); 

 Rose Spit, Departure Bay, Northumberland Channel, Friday Harbor. 



As the gonosome is still unknown, the species must remain in 

 this genus provisionally.
