MIOCENE MOLLUSC A AND CRUSTACEA. 113 



Formation ami localities: Mr. Cmirad's (iriginal specimens are cited as 

 from the Choptauk River, in Maryland. In New Jersey they ap^iear to 

 come from Shiloh, Jericho, and near Bridgeton, and at the two former 

 locahties are connnon. I have received them from the collection at Rutgers 

 College and from the National Museum — the latter having been collected 

 by Mr. Frank Burns.

"Subulate, whorls with a revolving impressed line below and near the 

 suture; beneath this line the whorls are convex; ribs longitudinal, curved, 

 acute, dislocated by the impressed line; revolving lines minute, crowded, 

 obsolete; columella sinuous. Length, 1^ inches. 



"Differs from CeritMum dislocatwn Say, in wanting the distant revolv- 

 ing lines, and the small dislocated portion of the ribs are [have] not a tul)er- 

 cular form; the aperture is longer and narrower." (Conrad.) 



The resemblance between this and T. dislocata Say is so great as to 

 require a close scrutiny to distinguish between them. The difference 

 between the "revolving [spiral] lines" of Say's species and the extremely 

 fine spiral lines of this one being the most important distinction; wliile the 

 dislocation of the vertical ridges here can hardly l)e said to amount to an 

 interruption, as it often does in Say's species. 



Formation and locality: Only four specimens of this form have been 

 obtained in the collections from the Miocene marls at Jericho, N.J. These 

 belong to the National Museum collections.
