HYDROIDS FROM VANCOUVER ISLAND 149 



G. Huntsman and by Messrs. Macoun, Spreadborough, and 

 Young off Amphitrite point near Ucluelet in 1909. (7) Material 

 collected off Queen Charlotte islands by Mr. Spreadborough 

 in 1910. 



In giving the names of the species I have made no attempt 

 at giving synonymy, but instead have referred to the page in 

 the paper on the West Coast Hydroids where the synonymy 

 may be obtained. 



Vancouver Island Hydroids. 



Endocrypta huntsmani Fraser.— (p. 19). The generic name 

 Crypta was at first used for this species, but later it was found 

 that the name was preoccupied in both the Mollusca and the 

 Coleoptera and notice of the change was published in Science 

 Vol. XXXV, No. 893. Feb. 9, 1912, p. 216. 



It would be of interest to investigate further the life history 

 of this species. Its habitat, so far as I am aware, is entirely 

 unique. The location in which it is found seems a very suitable 

 one for obtaining a food supply, while the fact that so many 

 colonies were found would indicate that their presence was not 

 a matter of accident. If one could only find out how much of 

 the life cycle was passed within the branchial basket of the 

 ascidian it might give an indication of the way in which these 

 colonies are implanted without being injured in any way by the 

 ascidian. I knew nothing about the species until within a few 

 days of my departure, hence though I got a good many colonies 

 they were almost all obtained in the one day, and were all within 

 a comparatively narrow range of development. 



The ascidians containing the specimens were all obtained by 

 dredging in the shallow water near the station, principally be- 

 tween Brandon island and the mainland and seldom in more 

 than 7 or 8 fathoms of water. 



Syncoryne mirabilis (Agassiz). — (p. 21). This species has 

 not been reported from Canadian waters from the west coast 

 unless Agassiz' reference from the Gulf of Georgia applies. In 

 the material collected by Mr. Spreadborough at Queen Char- 

 lotte islands there were numerous specimens growing on Gar- 

 veia annulata.
