464 THE CANADIAN NATURALIST. [Vol. viii. 



ON SOME MARINE INVERTEBRATA FROM THE 

 WEST COAST OF NORTH AMERICA. 



By J. F. Whitbaves. 



During Mr. Richardson's explorations ou Vancouver Island 

 and the coast of British Columbia, on behalf of the Geological 

 cal Survey of Canada, in the summer seasons of 1874 and 1875, 

 no opportunity was neglected for obtaining specimens of interest 

 to the zoologist or botanist. In the first of these years, an exam- 

 ination of the coast was made, from Victoria, V. I., to the mouth 

 of the Stickeen River in Alaska, as described in the " Report of 

 Progress for 1874-75," and some dredging was done in Burrard's 

 inlet, also in McLaughlin's bay on Campbell Islaud. The fol- 

 lowing year, in addition to shore collecting near Victoria, succes- 

 ful dredging operations were carried on in the Gulf of Georgia, 

 between Victoria Harbour and Race Island Lighthouse, also in 

 Deep Bay opposite Denman Island, and near the north-west end 

 of Texada Island. A small but interesting series of littoral 

 Algae, Hydroids, Polyzoa and Crustaceans, from the immediate 

 vicinity of Victoria, was presented to the museum of the Survey, 

 through Mr. Richardson, by Mr. R. Middleton, of that city, in 

 1875. The whole of the zoological specimens obtained during 

 these two years were deposited temporarily in the Museum of the 

 Natural History Society of Montreal, with the understanding 

 that the writer, who was then Curator to the Society, would ex- 

 amine and report upon them. 



The Crustacea, with the exception of the Echidnocerus, have 

 been kindly determined by Prof. S. I. Smith, and the Hydrozoa 

 by Prof. S. F. Clark, both of Yale College. The writer is also 

 indebted to Professors Verrill and A. Agassiz, and to Mr. W. H. 

 Dall for valuable assistance in the identification of some of tho 

 Alcyonaria, Echinodermata and Mollusca.
