longitudinalibus nubeculata ; anfractibus planulatis, Isevigatis, 

 politis, integris, inferne prope suturam albo anguste fasciatis, 

 ultimo fasciato ; apertura efFusa ; columella leevi, truncata. 



Shell elongated, conico-subulate, acuminate, milky white, 

 figured with aggregated slightly waved pale brown strigee, 

 ceasing suddenly a little above the suture, thus appearing nar- 

 rowly banded with white ; whorls smooth, entire, the last elon- 

 gated. Aperture oval, effuse, without the least appearance of 

 a canal. Columella, smooth, straight, and truncate. 



Habitat unknown.

Testa subulata, turrita, nitida, longitudinaliter plico-striata, 

 cinerea, caerulescente, rarius carnea, strigis albis ornata; 

 anfractibus planulatis, superne sulco divisis, transversim in-

 tvuscula. 



Shell subulate, acuminate, turrited, longitudinally striated, 

 but varying greatly in intensity, sometimes coarse, even to 

 folds, at others nearly smooth and polished ; fluctuating 

 equally in colour, the prevailing being a gray or blueish ash 

 colour, and varying to chesnut and flesh colour ; whorls 

 divided by a groove, and disposed to be banded transversely ; 

 last whorl rather elongated ; columella straight, and slightly 

 truncate. The variety of character assumed by different indi- 

 viduals is no doubt the reason why it has been described more 

 than once. M. Kiener's figure, t. 9. f. 18, represents T. stri- 

 gilata, and not this shell.
