Shell shortly fusiform, with short canal, smooth, shining, yellowish-white, with more or 

 less conspicuous traces of red-brown streaks on ribs; whorls 7, of which a little more than one 

 forms a convex, smooth nucleus; post-nuclear whorls separated by a deep, waved suture, convex, 

 angular, slightly excavated at their upper part, with rather strong, rounded, oblique, axial ribs, 

 1 1 in number on last whorl, that behind the peristome stronger; these ribs are pointedly tubercled 

 about their median part, just below the excavation in upper whorls, at the shoulder of last whorl, 

 on this latter the ribs are fainter towards the base, otherwise the shell is nearly smooth, but 

 for very faint, remote spirals, a little more conspicuous on canal, and fme growth-lines. Aperture 

 oval, angular above, with a wide, short canal below ; peristome thin, broken, with a shallow 

 sinus above. Columellar margin concave, slightly directed to the left below, with a rather thin 

 layer of enamel, stronger near its base.

The specimen is very large, being 1 1 instead of 8 Mill. in length, but otherwise exactly 

 agrees with Reeve's figure and description. A close spiral striation, mentioned by Tryon, seems 

 to have been overlooked by Reeve.

Shell elongately pyramidal, with short canal, strong, yellowish-brown. Whorls 9 or 10, 

 of which the uppermost is eroded, foliowed by about 2 closely ribbed ones; subsequent whorls 

 slightly convex, with a deep suture, hexagonal by 6 continuous, rounded ribs. Sculpture con- 

 sisting of numerous spirals, of which the peripheral one and 2 or 3 lower ones are more pro- 

 minent, at all there are on penultimate whorl of largest specimen about 10 stronger spirals 

 and 3 intermediate ones in each interstice, of these spirals the median one is again stronger than 

 the other ones (in the smaller specimen this arrangement is less conspicuous) ; each of these 

 spirals is closely covered with a row of granules, having the character of compressed squamae 

 on the principal lirae, this sculpture extends also over the whole last whorl and canal. Aperture 

 short, oval, rounded above, with a short, narrow canal below ; peristome rather blunt, with a 

 shallow sinus above and a strong rounded rib externally, 3 tooth-like tubercles in its interior, 

 of which the uppermost is the largest; columellar margin nearly straight, but slightly concave 

 above, directed to the left below, with a strong layer of enamel, only appressed above, free 

 below, interiorly with a strong tubercle above and 2 flat plaits about its median part, each 



plait divided by a groove.
