Trophosome, — Stem fascicled but the various parts that go to 

 make it up are more lightly held together than is usual in a polysiphonic 

 stem. Sometimes branches, that give rise to two or more pedicels, 

 come off the main stem but more commonly the pedicels arise directly 

 from it. The whole colony may reach a height of 50 mm. The 

 pedicels vary much in length and in the amount of their annulation; 

 some of them are regularly annulated throughout while others are 

 wrinkled rather than annulated. There is little regularity in their 

 arrangement or in their attitude as compared with the stem. The 

 hydranth is large, fusiform, with the base enclosed in perisarc, which 

 extends to the base of the tentacles; they are about 16 in number. 



Gonosome. — The gonophores are borne on the stem and on the 

 stolon. The pedicel is branch-like, covered with thick perisarc 

 which ends in a shallow cup-like expansion below the sporosac, the 

 remains of a ruptured sporosac envelope. The sporosac is large, 

 oval or nearly globular. 



Color. — Hydranths and pedicels are light orange, main stem and 

 sporosacs a deeper orange. 



Distribution. — Port Renfrew, Ucluelet, Queen Charlotte Is. 

 (Fraser); Clayuquot Sound, Northumberland Channel, Dodds 

 Narrows Gabriola Pass, Whaleboat Passage, off Shaw I., San Juan 

 Channel, Friday Harbor. Very abundant in the neighbourhood 

 of Friday Harbor, particularly off Point Richardson. 



This species is very generally found growing through or on a 

 species of sponge. It is much overgrown with other hydroids, 

 especially with Campanularia urceolata. 



Garveia grœnlandica Levinsen 



PI. IV, Fig. 8 



Garveia grœnlandica Levinsen, Meduser, Ctenophorer og Hydroider 



fra Grcenlands Vestkyst, 1893, p. 155. 



Trophosome. — Stems arising from a reticulated stolon, simple, 

 usually unbranched but sometimes a main stem gives rise to two or 

 three branches each similar to the unbranched stem; much more 

 delicate than Garveia annulata; pedicels vary in length from 2 to 6 

 mm.; perisarc wrinkled or somewhat irregularly annulated, passing
