HYDROIDS FROM VANCOUVER ISLAND 
155 
Thuiaria fabricii (Levinsen). — (p. 76). Rare, found only 
in Northumberland strait. 
Thtjiaria similis (Clark). — (p. 77). Commonly dredged 
in Departure bay and Northumberland strait in 10-25 fathoms, 
but not so common here as in the San Juan archipelago. 
Thtjiaria thuja (Linnaeus). — (p, 78). Two specimens were 
obtained in material from Banks island. 
Aglaophenia struthionides (Murray). — (p. 80). Very 
common around the south end of the island from Victoria to 
Ucluelet but not observed north of Victoria on the east side of 
the island. The large clusters of long symmetrical plumes 
make this species one of the most conspicuous as well as the 
most beautiful of the hydroid forms in this region. 
Plumularia goodei Nutting. — (p. 82). A few* specimens of 
this delicate little plumularian were found near low water at 
Port Renfrew. 
Plumularia lagenifera Allman. — (p. 82). This is the 
commonest plumularian in the region, While Aglaophenia 
struthionides seems to have reached its northern limit near the 
southern end of the island, Plumularia lagenifera extends much 
farther north. Specimens were obtained by Mr. Taylor at 
Hope island and many specimens were obtained from De- 
parture bay and Northumberland strait. Much the finest 
specimens were obtained from Ucluelet. 
Plumularia palmeri Nutting. — (p. 84). A few specimens 
were obtained at Ucluelet.
