Lister, pi. 211. f. 46. 
Shell blackish horn-color, semitransparent, oval, rather 
convex, with numerous very fine regular longitudinal ribs j 
the sides abruptly turned in and flattened, without the ribs, 
hut marked with a few irregular striae; the front margin a: 
little indented on each side and projecting in the middle : 
one valve produced into an elongated incurved and pointed 
beak, like a parrot’s bill ; the other oval and rather flat ; 
the perforation somewhat triangular : inside dull greyish- 
white, with a strong tooth-like projection each side a little 
below the-beak, and which reaches down the incurvature 
of the sides in a strong rib-like form : length nearly an inch 
and a quarter ; breadth' an inch. 
A specimen of this very rare shell we found on the shore 
about a mile to the east of Teignmouth, after a severe gale, 
and have since seen several broken fragments: but we suspect 
they come from very great depths, v. m.
