Connecticut to the Arctic Oceati: uorthern coasts of Europe; North 
Pacific ; south on the coast of Asia to Hakodadi, Japan; and, perhaps 
(as WW. erpansa, a doubtful variety), on the west coast of America south 
to Puget Sound. Off Block Island, in 29 fathoms, rare: Casco Bay, 3 
to 60 fathoms, not uncommon: Quahog Bay. Maine, 3 to 5 fathoms, soft 
mud, large and abundant: Bay of Fundy, 4to 80 fathoms. Stonington 
and Stratford, Connecticut (Linsley): Saint George’s Bank (S. IL. 
Smith). Fossil in the Post-Pliocene of Maine, New Brunswick, Canada, 
Labrador, Scandinavia, and Great Britain. 
The Tellina tenera Leach, 1815 (non Say), has been regarded as a 
synonym of this species by most writers; Moérch considers it identical 
with VU. fragilis.

Shell smooth, shining, more or less iridescent. with very fine concen- 
tric strie. Form similar to that of A. tencr. 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 subtrrncate 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
