HYDRO IDS FROM VANCOUVER ISLAND 
151 
Campantjlaria raridentata Alder. — (p. 32.) Specimens 
from Departure bay and from material obtained by Mr. Taylor, 
from the Queen Charlotte islands, were found growing on fucus 
holdfasts. 
Campantjlaria urceolata Clark.— (p, 33). Apparently very 
abundant at Queen Charlotte islands, as, in the material collected 
by Mr. Taylor as well as that collected by Mr. Spreadborough, 
the colonies growing over other hydroids were numerous. It 
was quite plentiful in the Dodds Narrows material, growing on 
Abietinaria filicula and at Port Renfrew on Eudendrium calif or- 
nicum. 
Campantjlaria verticillata (Linnaeus). — (p. 33). The best 
specimens were obtained by Mr. Taylor from Queen Charlotte 
islands; those from Dodds narrows were badly broken up and 
there were not many of them. 
Campantjlaria volubilis (Linnaeus). — (p. 34). Rather 
scarce in both Banks Island and Uelueiet material. 
Clytia edwardsi (Nutting). — (p. 34). Abundant, growing 
on the laminaria in shallow water east of the station in the bay. 
Eucopblla everta (Clark). — (p. 37). At Port Renfrew this 
species was growing on a small stalked ascidian and in Departure 
bay on laminaria in company with Sertularella turgida. 
Gonothyr^a clarki (Marktanner-Turneretscher). — (p. 37). 
This species and Clytia edwardsi are the commonest of the Cam- 
panularian species in the Departure Bay neighbourhood. 
This does not signify that they are found together. Clytia 
•i edwardsi is found almost entirely on laminaria within the bay; 
Gonothyrcea clarki is found growing on the smaller algae in tide 
pools in more exposed locations, e. g. on the outlying rocks at the 
east and the west of the entrance of Hammond bay. 
Obelia borealis Nutting. — (p. 38). Plentiful in the Uelueiet 
material. 
Obelia dichotoma (Linnaeus). — (p. 38). Not very plentiful 
in Departure bay. Specimens obtained from Newcastle island. 
Obelia dtjbia Nutting.— (p. 38). Not common though found 
in small quantities at Uelueiet, Dodds narrows, Departure bay, 
-and later at Queen Charlotte islands. 
Obelia griffini Calkins. — (p. 39.) But one colony found at 
Departure bay.
