mens from Ucluelet were collected along the shore and from 

 dredging in shallow water up to 30 fathoms. 



When I came to the University of Iowa last September, Prof. 

 C. C. Nutting placed at my disposal two collections from San 

 Juan Archipelago, not previously examined, the one made by 

 Mr. H. Moon, a graduate of the University of Iowa, and the other 

 .by Prof. T. Kincaid of the University of Washington, Seattle. 

 The collection belonging to the University and Prof. Nutting's 

 own collection, both extensive, have been available for reference 

 and comparison. A collection made at Canso, Nova Scotia, under 

 the supervision of Prof. R. Ramsay Wright, while connected with 

 the University of Toronto, was also of value in comparing the 

 West Coast forms with those on the Atlantic Coast. These col- 

 lections, then, form the basis for the work set forth in this paper. 



As so many contributions to Hydroid Literature were at hand,, 

 on the advice of Prof. Nutting, I decided to extend the work to 

 include all the references to Hydroid distribution on the West 

 Coast up to the present time. The paper, therefore, is intended 

 to serve two purposes, (1) To give a list of all the species found 

 in the new material from the Vancouver Island Region, with the 

 description of any new species found or any new points of in- 

 terest observed in connection with forms already described. 

 (2) To give a full list of species known to exist on the West 

 Coast of North America, with the full recorded distribution of 

 each species along this coast. 



The Hydroid history of the Coast as far as collecting is con- 

 cerned, up until 1901, has been given by Prof. Nutting in his 

 paper on the Harriman Hydroids. Since that time he has ex- 

 tended the list of Sertularians in his monographic work of 1904. 

 Dr. Torrey reported several new species and extended the range 

 of many others, chiefly along the California Coast, by his paper 

 on Pacific Hydroids in 1902, and that on San Diego Hydroids in 

 1904. In 1907, E. Jaderholm in his paper "Zur Kenntnis der 

 Hydroiden-fauna des Beringgmeeres ", reported several other 

 species from the Bering Sea, two of which, Halecium telescop- 

 icum and Stegopoma pUcatile, had not previously been reported 

 from the West Coast. 



Although I have added but seven new species and ten more 

 that had not been reported from the Coast previously, the closer 

 connection made between the Alaskan and Californian forms by
