Connecticut to the Arctic Ocean ; northern coasts of Europe; North 
Pacific ; south on the coast of Asia to Hakodadi, Japan; and, perhaps 
(as JM. expansa, a doubtful variety), on the west coast of America south 
to Puget Sound. Off Block Island, in 29 fathoms, rare; Casco Bay, 5 
to 60 fathoms, not uncommon; Quahog Bay, Maine, 5 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 Tellina tenera Leach, 1818 (non Say), has been regarded as a 
synonym of this species by most writers; Mérch considers it identical 
with MW. fragilis.

Shell smooth, shining, more or less iridescent, with very fine concen- 
trie strie. Torm 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 subtruncate at the end; 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. tener, but is sometimes as thin. Color, pink, light straw-color, or
