« This small shell ressembles no species of the genus 

 known to us, except M. Suavis Souv. J. conc. 1858; 

 the présent species, however, differs in not havhig its 

 last whorl, as reguiarly cylindrical, but abruptly inclined 

 to on side , marking the aperture shorter and more con- 

 tracted, and giving the shell a somewhat deformed 

 appearence ; the two lower plaits on the columella are of 

 a différent character instead of being nearly transverse, 

 as are the two upper ones, they are almost perpendicular; 

 on the last whorl instead of three, there are only two 

 pink bands, both very broad, the band on the upper 

 whorl is also just abowe the suture not beneath il. 

 long. 4 1/4 mil., diam. 2 1/4 milL, long, apert, 2 mill. »
