specimens are in the museum of Geological and Natural Jlisloiy Survey 

 at Ottawa. L. subauriculata is a shell of very wide range, occurring on 

 both sides of the Atlantic from the extreme north to the Canary Islands 

 on the east and to Florida on the west side of the ocean. 



Its range in depth, according to Dr. Dall, is " 6 to 843 fathoms." It 

 has also a considerable range in time, being, according to .Tett'reys, a 

 fossil of the British Coralline Crag. 



Joeing rather common in the Californian region, and also to the 

 north of us, it is to be expected that il will be found in other localities 

 on the Vancouver coasts. 



BEYOPHILA. Carpenter. 



IG. Bryophila setosa, Cpr. 

 Ann. Mag. Nat. Hist., series a, vol. xili., p. :il4 (April, 1S()4). 



Described from Cape St. Lticas (Xantus) and recorded also from 

 Californian localities. 



Our first British Columbian record is that of Dr. Dawson : " Virago 

 Sound. Queen Charlotte Islands, in 8-15 fathoms, 4 tine living specimens.'' 



I have a single specimen which was picked up on the sands at 

 Alert Bay by Mr. E. S. Wilkinson, and which, from a comparison with 

 one of Mr. Xantus's original lot, I believe to belong to this species. 



MYTILUS, Linne.

Common between tides and growing to a veiy large size. It is 

 eaten by the Indians, and in its season is often to be seen on sale in the 

 Victoria tish stores. 



18. Mytilus edulis, Linne. 



Syst. Nat., ed. xii., vol. i.. pt. 2, p. 11.57, no. 'lr>:\ <17()7). = M. frossidns. (touUI, 

 and many other synonyms. 



Everywhere between tides. It is regularly on .sale in Victoria, but 

 is not valued as an article of food to anything like the same extent as in 

 Jul rope or eastern America. 



M. edulis has a ver}'^ extended range, being found throughout the 

 whole northern hemisphere. ' 



' Northern localities for M. edulis, and for the following British Columbian 

 •species, are given in a " Catalogue of shells from Bering Sea and the adjacent portions 

 of the Arctic Ocean " which was contributed by Dr. Dall, 20 years ago, to the 

 Proceedings of the Californian Academy of Sciences (vol. o, p. 24(5-2ii:i, 1874): Mi/filiis
