ing the suture; umbilicus deep, spiral; aperture entire circular; outer lip crenulated 

 within; inner lip with one tooth. 



But one specimen yet discovered in the Pleiocene, and from this our figure is taken ; we 

 found another on the sea-shore of Kiawah Island, that appears to be recent, thotigh possi- 

 bly it is a Post Pleiocene shell, from the sub-marine beds of the coast. We name it after 

 Kiawah Island.

Desckiption. Shell sub-conical, whorls slightly angular near their base, with promi- 

 nent spiral beaded lines, alternating in size ; striae on the base nearly smooth, not crenu- 

 lated; sub-umbilicated ; aperture obliquely quadrangular. — Con. 



Our specimen only differs from the above description in having two beaded lines on the 

 base near the umbilicus. We have as yet discovered only a single individual, but it is 

 common in the Virginia Meiocene.
