regular net-work of tubes that form the stolon. Their minute- 

 ness corresponds very well with Wright's description, as even 

 the branched specimen was less than 1 mm. long and the un- 

 branched ones were little more than half that. 



CAMPANULINA RUGOSA Nutting 

 Campanulina rugosa Nutting, Hydroids of the Harriman Ex., 1901, p. 176. 

 Distribution. — Juneau Alaska (Nutting) ; West Seattle, in 

 Prof. Kincaid's Collection. 



Genus CUSPIDELLA 



Trophosonie. — Hydrothec^ tubular, sessile on a creeping root- 

 stock. 



Gonosome. — Unknown. 



CUSPIDELLA HUMILIS (Alder) 



Campamdaria Immilis Alder, Trans. Tyne. F. C. V., 1862, p. 239. 

 Ctispidella humilis Hincks, Ann. and Mag. N. H., 3rd Ser. 18, 1866, p. 298. 

 Cuspidella humilis Hincks, British Hydroid Zoophytes, 1868, p. 209. 



Distribution. — Departure Bay, San Juan Archipelago. 



This species has generally been credited to Hincks, who seems

Genus LOVENELLA 



Trophosonie. — Colony unbranched or slightly branched. Hy- 

 drothecae turbinate. Margin more distinct than in any other 

 genus of the family. 



Gonosome. — Gonophores producing bell-shaped medusse with 

 eight tentacles and four lithocysts.

 Sars, no very definite description has been given. On that ac-
