bly allied to T. punicea, but I have never found it so 

 far north as the state of New Jersey. It is much more 

 elongated than the latter, the striae are far more distinct, 

 and it is entirely and always destitute of the rose co- 

 loured bands and lines, such as are represented in Born's 

 figure of that shell. It cannot be the T. angulosa of 

 Gmelin, as that species is described to be suborbicular, 

 and to have the lateral teeth remote, whereas the alternata 

 has but one of the lateral teeth remote. 



It is abundant in the Upper Tertiary or Newer Plio- 

 cene beds near Newbern, North Carolina. — Editor.
