men, we f^ceuivd more than 7,000 specimens of 88 species of mollusca, 

 including one s])ecies, Rictaxis punctoccelata , that I had not before 

 observed in this province. 



I had myself collected on a previous occasion in the same locality ; 

 and during a number of years I hav^e dredged and made shore collec- 

 tions near Yictoiia ; and at Vesuvius Bay and Ganges Harbour, on Salt 

 Spring Island ; and at Comox. 1 have not so far had any opportunity 

 of personally visiting more northern or west coast localities. 



In the notes that follow, I have endeavoured to give under each 

 species, a reference to the original description and figure ; secondh\ 

 Huch synonyms as appear necessary to connect this list with pi'evious 

 papers on the same subject, likely to be consulted by the student ; 

 thirdly, a list of the localities, wiihin the province, in which the shell 

 has been found ; and lastl}', some brief notes as to its station, relative 

 abundance, and so forth. 



The determination of the shells themselves may be accepted, I 

 think, as fairly accurate. I have had opportunities of studying the 

 large collections in the Museum of the Geological Survej' in Ottawa, 

 and also the Vancouver shells in the Natural History Museum at South 

 Kensington. Moreover, most of the dithcult species have been submitted 

 at different times to Dr. Dall, who has most kindly helped me, during 

 several years past, in identifying puzzling specimens. 



In the arrangement of the species I have endeavoured to follow, as 

 nearly as I could, the classitication adopted by Dr. Dall in his most use- 

 ful catalogue of the shells of the Atlantic coast of the United States, 

 published in 1889, as Bulletin 37 of the U. S. National Museum. 



No attempt has been made to give a complete bibliography of the 

 subject, but the titles of a number of the most useful papers are given 

 in full in the following notes. Other useful papers, to which it is not 

 possible to refer at length here, have been contributed b}^ Drs. Cooper, 

 Dall, Stearns and Pilsbry to the American Journal of Concholog}^ and the 

 Proceedings of the Acaderaj^ of Natural Sciences (Philadelphia) the 

 California Academy of Sciences and the United States National Museum.
