Testa gradatim subulata, laevigata, polita, albida, flammeis 

 pallidis fuscis ornata ; anfractibus subplanulatis, superne linea 

 impressa divisis, area superiore spirae leeviter tuberculata ; an- 

 fractu ultimo prope basin fasciato ; apertura inferne subeffusa ; 

 columella nuda, breviuscula. 



Shell subulate, turrited, smooth and polished, white, with 

 pale brown flames ; whorls flat, distinctly girdled near their 

 upper margin, the superior area somewhat tubercled, last 

 whorl banded at the base. Aperture oval, effuse, without any 

 canal. Columella naked, smooth, truncate. 



Its nearest ally is T. dimidiata, than which it is far more 

 gradually subulate ; the upper area of the divided whorl is 

 raised and somewhat rounded ; the white is the base colour 

 of the shell, and the last whorl is distinctly banded.

Testa elongate subulata, turrita, polita, albescente, maculis 

 subquadratis saturatioribus seriatim cincta ; anfractibus vix

Shell elongated, subulate, turrited, polished, white, with 

 three series of cream-coloured square spots, of which the 

 middle is rather the larger; whorls flat, girdled above, desti-

 cuate. Canal very short. 



The name attached to this shell by M. Kiener had been 

 previously used by Mr. Sowerby, so that a change became 

 necessary.
