The specimens from Stat. 116 and 285 are young and have a somewhat misleading 

 appearance, by the closer sculpture. However the species is very variable in this respect, and 

 these specimens are connected to more typical ones by intermediate forms, f. i. those from 

 Stat. 313. Tryon says on this subject (I.e. p. 43): "The tubercles are numerous on the earlier 

 whorls, but (in some instances) coallesce into two large ones between the varices on the last 

 whorl of the adult. When the more numerous tubercles are persistent, the resemblance to the 

 next species (R. tuberculata) is striking".
