*In his account of the ‘‘ Edible Mollusca of Nova Scotia” (reprinted in Knight's Descr. 
Catalogue of the Fishes of N.S.), Willis shows us clearly by his description of their size and 
shapes, that by VW. gigantea he meant what is now called iW, solidissima, and by M, solidissima 
he meant our ™. oval’s. : 
+ Macoma fusca and prozima respectively. 
{ Considered by Gould as synonymes of Wacoma proxima and fusca, respectively. 
§ Meaning, of course, what is now considered var, Americana, Gould, or by some a distinct. 
species. 
|| Glycymeris siliqua. 
{ Synonom for S. rugosa, which is probably but a variety of S. arctica. 
** Misprint for Anatina papyracea.
