GASTEROPODA. 65 



C. Testa turritd, elongatd, fusiformi, spird elevatd ; apice acuminato ; longitudinaliter 

 costatd ; anfractibus super ne angulatis, supra pi anis ; costis distantibus rotundatis, lavigalis, 

 interstitiis obsolete striatis ; columella biplicatd ; labro inlus sulcato. 



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

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

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

 denticulated within ; aperture ovate, slightly canaliculate. 



Axis, 1| inch.

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 costse. In my specimens they are never more than ten in 

 one volution, and the shell is not quite so much coronated, although the costae are 

 produced at the upper part, but they are more obtuse. The specimens are some- 

 what altered, as the stria? 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 Vol. varicosa, 

 Broc, and says, p. 201, "labro sulcato; " in the second vol. p. 177, the character 

 is given as " labro intus lgevi." It may perhaps be so in its young state.

C. Testa turritd, subfusiformi ; longitudinaliter obsolete costulatd ; transversim striata, 

 columella biplicata, labro acuto, intus sulcato, canali brevissimd. 



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

 versely striated ; columella biplicate ; outer lip sharp, dentated within, with a sube- 

 marginate base. 



Axis, f of an inch.

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 denticulations. The striae upon the exterior are 

 large and coarse, amounting almost to ridges, and the longitudinal costae 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 denticulations represented in his figure. The 

 identification is therefore given with doubt.
