* These species complete the list of known Mollusca of the temperate and boreal faunae of our const, 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 arc 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.
