Moi^e elevated than T. monilifera; base more oblique; aperture 

 more produced ; and the golden-nacreous appearance wanting. 



T. CONCINNA A. Adams. Uiifigm-ed. 



Shell small, ovate-conic, imperforate, whitish, solid ; whorls a 

 little convex, subimbricating, separated by ])rofoundly canal-formed 

 sutures; finely crenulated below the sutures; covered with encir- 

 cling lirae, the interstices elegantly clathrate ; base convex ; aper- 

 ture oblique, semicircular; columella tortuous, terminating in a 

 tooth ; lip sub-thickened, obsoletely sulcate inside. {Ad.)

T. coREENSis Pease. PI. 63, fig. 26. 



Shell conoidal, rather thin, subdiaphanous, of a light gravish 

 fawn-color, cinereous at the base, and sparingly marked with 

 oblique stripes and small spots of deep brown. Whorls flattened ; 

 body-whorl large, rounded at its periphery, all ornamented with 

 transverse rows of close irregular sized granules, which become 

 almost obsolete near the base. Apex acute; suture canaliculated ; 

 base convex, imperforate ; outer lip sharp. Aperture large, breadth 

 and height equal, and pearly within. Columella oblique, with two 

 obtuse tubercles on its edge. (Pse.)

This species is closely related to T. monilifera Ad. It differs in 

 the aperture being smooth inside, and the whorls flat. The figure 

 of T. moniliferas also represents the sutural canal as being con- 

 tinued round the body-whorl. In the present species it terminates 

 with the suture. The columella is also quite different, descending 

 obliquely to the right. (Pse.)
