polish and. for its inflation, which continues far over 
the disk of the shell, and terminates very abruptly, 
near the margin. The circumference very nearly 
represents that of the C. calyculata, Drap., except 
that it is less curved below.: That shell, however, 
is flattish, and has prominent beaks. C. rhomboida, 
Say, approaches. in form to this species, but is much 
_ less inflated between the umbo and margin, has very 
coarse striz, and is destitute of the paler zones, which 
in this shell appear to be a constant character.
