 f. 32. 



T. testa ovali-oblonga, concentrice minutissime striata, sub-

 albo-biradiata. ; latere antico breviusculo ; lunula indistincta. 



Matter, more acuminated (particularly at the hinder end), and 

 much more finely striated, than T. floridella. The colour is a de-

 purple towards the apex, from which radiate two white lines, 

 dividing the surface into three parts.

A small purplish shell, with very fine concentric striae, radiated
