Shell elongato-fusiform, turreted, with an elevated spire, longitudinally costated, 

 obsoletely striated between the ribs ; whorls subangulated above, with the costje pro- 

 duced at the upper part, smooth and distant ; columella with two folds, outer lip 

 denticulated within ; aperture ovate, slightly canalicidate.

This species is very rare in my cabinet. It corresponds with the figure and description 

 given by Nyst, at the above reference, but I cannot consider it Vol. varicosa of Brocchi, 

 unless it be very much altered. It is, I imagine, the same as the one Dr. Philippi has 

 figured in his second volume, although the shape of the outer lip in his figure is more 

 expanded at the lower part, and his shell appears to have more and sharper costs. In 

 my specimens they are never more than ten in one volution, and the shell is not quite 

 so much coronated, although the costse are produced at the upper part, but they are 

 more obtuse. The specimens are somewhat altered, as the strise are nearly obsolete, 

 but the ribs appear smooth. In my Catalogue it was considered as a new species, 

 and the present identification rests upon Dr. Philippi's description, who considered it 

 in his first vol. as P'ol. varicosa, Broc, and says, p. 201, "labro sulcato;" in the 

 second vol. p. 177, the character is given as " labro intus laevi." It may perhaps be 

 so in its young state.

Shell turreted, elevated, subfusiform ; with obsolete longitudinal costte ; trans-

 ginate base.

This species is rare. The upper part of the volution is flattened, while it is convex 

 on the lower half. The outer lip is sharp, somewhat expanded, thickened within, and 

 has about nine or ten dcnticulations. The striaj upon the exterior are large and coarse, 

 amounting almost to ridges, and the longitudinal costte in some specimens are obsolete. 



Our shell has not the ridge-like appearance below the suture so visibly shown in 

 Brocchi's figure, nor are there any dcnticulations represented in his figure. The 

 identification is therefore given with doubt.
