NOTES ON A FEW BEITISH COLUMBIA MAEINE SHELLS. 



BY A. W. HANHAM, DUNCAN, B. C. 



The following notes do not refer necessarilv to rare, or even 

 uncommon species and are in some cases only a comparison of 

 common species occurring at different localities, sometimes not very 

 widely separated. 



Victoria is on the south end of Vancouver Island, inside the 

 Straits of Juan de Fiica; Maple Ray and Deparlure Bay lie on th« 

 East or inside coast of Vancouver Island, the former South o( 

 Departure Bay and distant about 30 miles ; both are siieltered <ii- 

 more or less land-locked ; Salt Spring Island lies along outside the 

 entrance to Maple Bay, and in the channel outside this entrance ihe 

 water is very deep. 



Terebratella transversa Sowerby. This species is common on the 

 underside of rocks at Maple Bay, and may be found not tar below 

 high water mark where the shore shelves steeply and the rocks are 

 well piled up. 



Peclen hastatus S(>werby and Fecten riihidvs Hinds. These species 

 occur together, and in the channels ofl'Nanaimo and Departure Bay 

 I have seen them brought up in the dredge by the pailtnl. Hoth 

 are sometimes coated, even on both valves, with a native sponge, 

 bright yellow in color when living, nanuMl Myxiiis pnrusiticn, Lambe. 



Hinnites giganteus Gray. Very tine specimens nmy be taken 

 among the rocks at Maple Bay at low tides, but the big fellows are 

 hard to detach without breaking or chipping the low»'r valve. A 

 nicely grown specimen makes a good a^h-tray.
