Connecticut to the Arctic Ocean ; northern coasts of Europe; North 

 Pacific ; south on the coast of Asia to Hakodadi, Japan ; and, perhaps 

 (as M. expansa, a doubtful variety), on the west coast of America south 

 to Puget Sound. Off Block Island, in 29 fathoms, rare; Casco Bay, 3 

 to GO fathoms, not uncommon ; Quahog Bay, Maine, 3 to 5 fathoms, soft 

 mud, large and abundant ; Bay of Fundy, 4 to 80 fathoms. Stonington 

 and Stratford, Connecticut (Linsley) ; Saint George s Bank (S. I. 

 Smith). Fossil in the Post-Pliocene of Maine, New Brunswick, Canada, 

 Labrador, Scandinavia, and Great Britain. 



The TelUna tenera Leach, 1818 (non Say), has been regarded as a 

 synonym of this species by most writers ; Morch considers it identical 

 with M. fragilis.

Shell smooth, shining, more or less iridescent, with very fine concen 

 tric stria*. Form similar to that of A. tener, but more oblong, and with 

 the anterior dorsal margin nearly straight, or even slightly concave ; 

 the beaks are at about the posterior third, and scarcely prominent ; the 

 posterior end slopes rapidly, and is. snbtruncate at the end 5 the ven 

 tral margin is but slightly convex in the middle, and sub-parallel with 

 the dorsal margin. The shell is often a little thickened, and firmer than 

 in A. tcner, but is sometimes as thin. Color, pink, light straw-color, or
