HTDROIDS PROM VANCOUVER ISLAND 
149 
G. Huntsman and by Messrs. Macoun, Spreadborough, and 
Young off Amphitrite point near TJclueletin 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 Hy droids 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 5 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.
