This shell is quite distinct from its congeners, and remarkable for 

 its rays of brown, more or less shaded with a greenish hue. It 

 belongs to the group of T. elongatus and Kotschyi. (Fischer.)

Shell narrowly perforated, conoidal, whitish-ashen, ornamented 

 with undulating, oblique, radiating chestnut or blackish stripes ;

 nodulose above ; above the carina obliquely nodulose, below the 

 carina spirally lirate; lirse 4; last whorl biangular, convex beneath, 

 and with 7 concentric brown-spotted lirie. Aperture subquadrate ;

Shell imperforate, acutely conical, rather thin ; whorls 9, planu- 

 late, ashen or brownish, maculate or obliquely striped with brown ;

Distinguished by its straightly conical form, peculiarly crispate 

 striation, and spiral granose like. 



Two trays of this species are before me ; one marked " Java," I 

 know not on whose authority ; the other was received from Dr. J. 

 C. Cox, from Port Jackson.
