Shell fusiform, transparently white, thin. Whorls about 9, ofwhichabout 3 form a reddish- 

 brown nucleus, with crossed riblets. Subsequent whorls angular, the upper part excavated, with 

 remote, faint, axial plicae below the suture, nearly lacking in last whorl; lowerpart with rounded, 

 more <>r less oblique ribs, ending above, just below the excavation, in bluntly pointed tubercles,

 and .1 few, scarcely appreciable, spiral striae: near the base of last whorl however and especially 

 on the rather long, narrow canal, numerous spirals make their appearance. Aperture elongately 

 ovate, with a sharp angle above, a narrow gutter-like canal below \ peristome thin (brol

1 smallest specimen is in the best condition and has served for description, the largest 

 one has the aperture less angular, which may be caused by having been broken and repaired; the 

 characters are not very prominent, but the species is certainly different from the former ones.

From the same locality, a heavily broken shell, with the lower half of whorls spirally 

 grooved. 7 grooves on penultimate whorl, has been dredged; the specimen is larger, but other- 

 wise I see no differences of much importance, the more so, as the two specimens of the type 

 are even not perfectly identical; as a large portion of last whorl is broken away, the shell 

 appears to be much more slender, but if complete, this difference would disappear for a good 

 deal, so I preferred to mention it only as a variety; the nucleus, though eroded, allows to
