The above description has necessarily been rendered so a- to 

 cover a little variat ion in form and sculpture, nece>sitated by the 

 inclusion of several names as synonyms; thus some specimens are 

 distorted, others straight, there is a difference in the convexity ..f 

 the whorls, and some are smooth, varying to those in which faint 

 .-piral stria- are perceptible. The synonymy includes R. deform!*.
