about three-quarters of a mile northeast of the Atlantic Coast Line 

 railway station at Bainbridge; Vaughan, Cooke, and Mansfield, 

 1914. U. S. Nat. Mus. Cat. No. 166797. Also in the Jacksonian

This species by inadvertance was not figured in the Wagner Trans- 

 actions and the name was omitted from the index of part 1 of the 

 volume. It has some resemblance to the '' Natica pTiasianeUoides

 of Cuba, proofs of the plates of which, possessed by the U. S. Geo-

 species, however, is larger, more ovate, with a shorter spire and much 

 less elegant form.
