[fraser] HYDROIDS OF THE VANCOUVER ISLAND REGION 165 



Trophosome. — Stem stout, fascicled, densely branched; one, two 

 or three branchlets or pedicels may arise from the same node; dis- 

 tally the pedicels are often in groups of three; the node is not always 

 distinctly marked but usually shows plainly just above the branch or 

 pedicel is given off; branches and pedicels may be wavy in outline; 

 hydrophores with much everted rim. 



Gonosome. — Unknown. 



Distribution. — Bremerton (Calkins); Port Renfrew, Ucluelet 

 San Juan Archipelago (Fraser); off Massett, off Rose Spit, Dodds 

 Narrows, off O'Neale I., Friday Harbor, Puget Sound.

Trophosome. — -Main stem coarse, erect, strongly fascicled; the 

 branches coming off from the main stem are simple and unbranched 

 except that a small proximal portion may be fascicled, pinnately ar- 

 ranged with much regularity; each branch usually passes to its ex- 

 tremity without forking. The branch is divided into internodes by 

 nodes that are nearly transverse; from the distal end of each internode 

 is given off the pedicel for a hydrophore, this pedicel being long but 

 showing no sign of a joint; commonly the hydrophore is reduplicated 

 one to several times but in each case there is a long portion inter- 

 vening. The margin of the hydrophore is very little everted; hy- 

 dranth large, with 12-14 tentacles. 



Gonosome. — Male gonangia broadly club-shaped, with distinct 

 pedicels arising in rows from the branches just at the point where the 

 pedicels are given off. 



Distribution. — Nanoose Bay, off West Rocks, Departure Bay, 

 off Matia I. 



This species seems to have got rather far afield as the nearest 

 point at which it has been reported is off Patagonia but the resem- 

 blance to Allman's figures is so marked there can scarcely be any'doubt 

 that it is the same species.

Trophosome. — Stem fascicled, erect, rigid; primary branches 

 fascicled, few, long, running in the same direction as the main stem;
