XV. — Hydroids from Vancouver Island. 



By C. McLean Fbaser. 



This report on the Vancouver Island Hydroids contains 

 nothing essentially new, with the exception of some references 

 to material collected in 1910 by Mr. W. Spreadborough in the 

 neighbourhood of the Queen Charlotte islands. The basis for 

 the report is the material already worked up for the paper on 

 "The Hydroids of the west coast of North America", 

 published in May 1911, as a Bulletin from the laboratories of 

 natural history of the State University of Iowa. 



The purpose of the report is simply to put in one list all the 

 species that have been collected from the coasts of Vancouver 

 island and to give, where possible, some notes as to their habitat, 

 etc., that may be useful to anyone collecting hydroids in these 

 waters. No one realizes more fully than the writer does, that 

 this list represents but very poorly the hydroid fauna of the 

 district, but everything must have a beginning, and what has 

 been done already will form a basis for future work. 



Judging from the luxuriance of the specimens obtained from 

 the west coast of the island and on northward to the Queen Char- 

 lotte islands, I am firmly convinced that some systematic 

 dredging would bring to light a hydroid fauna which would 

 equal in richness that of any other coast. Nor is it necessary 

 to stop at Queen Charlotte islands, as the work that has been 

 done off the coast of Alaska gives an indication of how rich the 

 fauna is in that region. Between Vancouver island and the 

 mainland at all points are conditions quite different from those
