* These species complete the list of known Mollusca of the temperate and boreal faune of our coast, and many of 
them may yet be found south of lat. 49°, Others will doubtless prove identical with species of the first list, or to have 
been wrongly located on our coast. By adding to them all mentioned before as found either at Sitka or on each side 
of that place, the Mollusca of the locality may be approximately known. It is likely that several Arctic species also 
occur there, besides those mentioned in the first list, as there are no fixed limits to the regions, though pretty well sep- 
arated by the peninsula of Aliaska. Some of the Lower California species, especially terrestrial, may be found to be 
limited to the temperate zone, but this is yet undecided.
