[fraser] HYDROIDS OF THE VANCOUVER ISLAND REGION 175 



up in the same direction as the stem, the distal portion curving out- 

 ward. 



Gonosome. — The gonangia of the coppinia mass as seen from the 

 surface are hexagonal with a projection containing the orifice at the 

 centre; the elongated hydrothecse come out at intervals among them. 



Distribution. — Puget Sound (Nutting); Puget Sound (Torrey); 

 Banks I., Departure Bay, Dodds Narrows, Ucluelet, Port Renfrew, 

 San Juan Archipelago (Fraser); found almost everywhere that col- 

 lections have been made from Queen Charlotte Is. to Puget Sound.

Trophosomc. — Stem fascicled, with many large branches regularly 

 arranged sometimes all on the one side of the stem; pedicels long, with 

 3 or 4 twists, passing out at an angle of more than 45° with the stem; 

 hydrothecse rather large with the lower side usually more nearly in 

 line with the pedicel than the upper side; the margin is at right angles 

 to the wall of the hydrotheca. 



Gonosome. — "Coppinia with small irregular facets and tubes 

 l hat are very long and thin and curved in a spiral like a watch-spring" 

 ( Bonnevie) . 



Distribution. — Puget Sound (Nutting); San Juan Archipelago 

 (Fraser); off Cape Edenshaw, Swiftsure Shoal, north of Gabriola I., 

 Cabriola Reefs. 



Although it was in this species that Levinsen first found that the 

 mass of gonangia belonged to the specimen to which it was attached 

 and was not a distinct species of the genus Coppinia, I have not been 

 able to find the coppinia. The description and the figure are taken 

 from Bonnevie, who, perhaps better than any other other, has made 

 clear the distinction between this species and L. gracillima. 



The specimen I referred to in my West Coast paper as L. grandis, 

 I now believe to be but L. fruticosa with larger hydrothecse than is 

 usual in the other specimens obtained.

Trophosome. — Stem fascicled, very much branched, but without 

 the distinct main stem present in L. dumosa and L. fruticosa; the
