321. Cytilus sericeits Forst., varius Fab , trivittatus Mels. 



These names seem to indicate mere differences in the color and 

 arrangement of the pubescence. I have seen many specimens from 

 various phices in Europe and America ; were the so-called species 

 deprived of pubescence and mixed, I know of no character by which 

 they could be separated. The individuals are abundant when found.

 to Hudson Bay (the Green Mountains, Vermont, Mount Washington, 

 N. H. ; Nova Scotia ; Canada ; Michigan ; the Lake Superior region.
