Characteristically to be recognized by its white shining surface, 

 and by the single acute median carination on the second and third 

 whorls, the next whorl, in common with the rest, being longi- 

 tudinally ribbed. These ribs are crossed on the fourth and fifth 

 whorls by two spiral lira?, on the sixth by three, and on the upper 

 part of the body-whorl by five, the ribs appearing, through a lens, 

 senticose at the points of junction. The lower part of the body- 

 whorl is rounded and spirally closely striate.

Not, perhaps, quite full-grown, as both the specimens examined 

 have the outer lip imperfect, and it is not possible to give any 

 particulars about the sinus. The oblique, acute, longitudinal ribs, 

 and the incrassate, subventricose, upper whorls seem characteristic.
