distance below the periphery, about twelve nodes occurring upon the 

 outer volution; the last volution rather rapidly contracting below and 

 produced into a short anterior beak ; columellar cavity of moderate width, 

 bearing the impressions of three rather faint revolving folds. Only the 

 internal casts of this species have been observed. These resemble similar 

 casts of T. alabamensis, but they are always shorter, with the volutions 

 less regularly rounded over the periphery, and they do not attain so large 

 a size. They differ from the casts of T. parva in being somewhat larger, 

 in having a more elevated spire and in the more nearly vertical position 

 of the nodes. The species is, in fact, somewhat intermediate in its char- 

 acters between T. alabamensis and T. parva, and has been observed only 

 from the Merchantville clay marl, while these other two species are both 

 Xavesink species." — Weller, 1907.
