The short, sharp, incurved spine which forms the termination of 

 each varix overhangs that part of the spire which is immediately

 Cuming in sandy mud at the depth of six fathoms. — W. J. B.

Obs. The sides of the canal in the specimen are broken, but the 

 canal does not appear to have been entire close to the aperture, 

 though the sides of it approximate there very nearly. — W. J. B. 



The fossil analogues of this genus have been hitherto found in the 

 London clay, calcaire grossier, and subapennine beds. — W, J. B.
