 This shell differs from A. Noa, with which it has been con- 

 founded by Schi oeter, and G meliu', in being generally smaller, 

 more ventricose, and narrower in proportion to the length ; 

 the longitudinal striae are rather finer, and are crossed trans- 

 versely by others which are acute and slightly imbricated ; 

 the anterior end, moreover, in A. Noae, forms a right angle 

 with the hinge, but in this species it is oblique, and it is not 

 marked with any stripes. 



naviculars. 4. Shell oblong-rhomboidal, com- 

 pressed in the middle, and longitudinally rib- 

 bed ; apices incurved, and very remote ; mar- 

 gin crenated at both ends.

Inhabits the coasts of St. Domingo. Bruguiere. 



Bruguiere says that this species is always small, and that the 

 breadth is about fifteen lines ; a specimen now before me is, 

 however, three-quarters of an inch long, and two inches and 

 a quarter broad, and is shorter and more contracted in the 

 middle than at either end ; the longitudinal ribs are rather 

 narrow and distant, particularly in the middle of the valves, 

 and the interstices are marked with minute slightly decus- 

 sated striae ; the straight margin which contains the hinge, 

 projects at both ends beyond the sides ; by which, and its cre- 

 nated margin, this species may be readily distinguished from 

 either of the foregoing ; the colour is white, with oblique 

 chestnut or orange zic-zac stripes like those of A. Note. 



plicata. 5. Shell rhomboidal, with decussated 

 striae on the sides, and plaited and angulated 

 at the anterior end ; margin crenated and 

 sinuated.
