The spirals above the angle, about fifteen in number, are much 

 finer than those upon the base. The slight umbilical perfora- 

 tion is perhaps sometimes covered by the reflexed columella. 



The colour may be variable, but in the unique example 

 examined the brown stripes are divided down the middle 

 by a whitish line. They are slightly undulating and the 

 basal lira? are spotted with the same colour, wdiich is blackisli 

 brown. The whorls are not quite flat, as the rounded keel, 

 which passes above the suture, causes a faint swelling at the 

 lower part.
