NOTES ON A FEW BRITISH COLUMBIA MAS IKE SHELLS. 



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



The following notes do not refer necessarily 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 tlie south end of Vancouver Island, inside the 

 Straits of Juan de Fuca ; Maple Bay and Departure Bay lie on tin- 

 East or inside coast of Vancouver Island, the former South *>! 

 Departure Bay and distant about 30 miles ; l>oth fire .--lioltered or 

 more or less land-locked; Salt Spring Island lies along oufsi/'e the 

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

 water is very deep. 



TerebratfUa tram- versa Sowerby. This species is common on the 

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

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

 well piled up. 



Fecten hastatus Sowerby and Pecten rubidus Hinds. These species 

 occur together, and in the channels ofFNanaimo and Departure Bay 

 I have seen them brought up in the dredge by the pailful. Both 

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

 bright yellow in color when living, named Myxitis parasitica, Lambe. 



Hinnites giganteus Gray. Very fine specimens mny be taken 

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

 hard to detach without breaking or chipping the lower valve. A 

 nicely grown specimen makes a good ash-tray.
