XXIV APPENDIX. 



Obs. Wc have formerly received this shell from 

 Senegal, wherefore we at first supposed it might he 

 Lamarek's T. Senegalensis ; upon examitiation, how- 

 ever, it does not accord with his description. Our 

 shell is of a light hrown colour, the upper part of the 

 volutions above the impressed line arc regularly 

 spotted with dark brown ; the spots on the lower

 grooves of the upper volutions are iuterruptcd by
