Description. Shell fusiform with six foliated reflected laminae; whorls angular and 

 carinated, aperture ovate, beak recurved. 



Mr. Conrad informs us it is but lately that specimens of this shell have been discovered 

 with the erect tooth on the labrum, which places it in his sub-genus Cerostoma. It is a 

 common shell of the Meiocene of Virginia; but a single specimen yet found in the Pleio- 

 cene of South Carolina that we know of, and that is imperfect, the spire is broken off, as 

 represented in the figure.
