OS MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. C27 



variations of foi-m in large numbers of individuals, but by the discovery ■ f 

 several new species and the addition to the district-fauna of many othei . 

 The duplicates are made-up in aeries for distribution by the Smithsonian 

 Institution ; and, though of the worst quality from a "collector's " point of 

 ^•^ew, they will be found very 8er^'iceable by real students, being carefully 

 named in accordance with this Report. He has now received a dredge, con- 

 structed for him by Dr. Stimpson; and if he succeeds in training the young 

 Indians to use it, there is little doubt that a rich harvest of fresh materials 

 will shortly be obtained. Some of the collections were made on the neigh- 

 bouring shores of Vancouver's Island, among which was a large seri<-s of 

 Pichi/poma (jihberosum, Chem., with attached Uivov.ia, ooth of an essentially 

 Eastern Pacific type, the former ha\-ing been brought from Japan by Mr. A. 

 Adams. The Indians have taken a fancy to the opercula of this shell for the 

 purpose of ornamenting their canoes. As it is an article of trade among 

 thc>mselves, it is remarkable that so large a sliell should have so long escaped 

 the notice of collectors. Dead specimens have been washed-up in California; 

 but it is not known even to enter the Straits of De Fiica alive. The shore- 

 pickings of the Indian children, which have already added 2-5 species to 

 science, are singularly free (rom baUast-importations, although they present 

 a few (supposed) extra-limital shells, probably washed-up by the ocean 

 currents. The following are the sjjecies new to the Vancouver fauna ; the 

 remainder will be found tabulated in the 7th column of the general Table, 

 par. 112, infra.
