Shell slender, elongated, with a long, tapering, acute spire ; whorls, 
seven or eight, the lower ones broadly and nearly evenly rounded, 
the upper ones more or less cariuated in the middle ; suture strongly 
impressed, unusually oblique. The lower whorls are crossed by nu- 
merous (about twenty-four) close, narrow, not very prominent, flexuous 
ribs, which are decidedly excurved on the subsutural band ; on the 
body-whorl they fade out just below the middle. Strong, elevated, 
nodulous spiral lines, or cinguli, separated by narrower, deep grooves, 
cover the surface of all the whorls below the nucleus, crossing both 
the ribs and grooves; on the middle of two or three, or more, of the 
upper whorls, one of these spiral lines is stronger than the rest, form- 
ing a distinct carina; on the lower whorls the spiral lines are nar- 
rower in the grooves than where they cross the ribs, on which they 
are thickened, so as to form strong, elliptical nodules, with smoothish 
rounded tops; on the subsutural band the ribs and spiral lines are 
narrower and the nodules less distinct ; on the anterior part of the 
bodv-whorl the spiral cinguli become more crowded, with narrower 
grooves, and are not nodulous, though roughened bv the lines of 
growth; on the siphon they become much finer and closer. The nu- 
cleus is very prominent, the whorls separated by deep, very oblique 
sutures; the apical whorl is, at first, small and smooth, but two raised 
spiral lines commence on the first whorl ; on the second there are 
ihree to four, the two middle ones forming stronger carime ; on the 
third there are four to five, one of the middle ones becoming a more 
prominent carina, and on this whorl they are crossed by transverse 
ribs, rendering them nodulous. 
The aperture is rather small, oblong-ovate ; the posterior sinus is 
broad and shallow, but distinct ; below this the outer lip is evenly and 
broadly rounded; canal very short, straight, rather wide, but a little 
constricted by the incurvature of the lip, at its base; columella only 
a little curved, slightly sigmoid. Animal not observed. 
Color of the shell, pale chestnut-brown, with the canal and colu- 
mella, whitish,
