 the length ; the anterior portion is somewhat attenuated, 

 and has a \ery slight elevation upon its surface that 

 extends from the beak to the edge, it is truncated ; the 

 bend of the shell is inconsiderable ; the strias are hardly 

 to be discovered in some specimens, they so soon wear 

 off, and extend only a small distance from the anterior 

 extremity.
