NOTE ON A VARIETY OF PALUDESTRINA JENKINSI, 

 E. A. SMITH. 



By H. OVERTON, 



Sutton Coldtield. 



The shell hefe figured was collected l)y me some short time ago with 

 other specinieiis of P. ji^iihiu.fi, E. A. Smith, many of which of w^ere the 

 keeled form, from the canal at Muckley Corner, near Wall, Staffordshire. 



As will be seen from the figures there are a number of minute spikes 

 irregularly distri lUted around the keel of the different whorls. In size and 

 practically in all the other characters the shell is typical. 



If no such variety has hitherto been described I would suggest the 

 name acii/eafa, var. nov. 



I am more interested, however, in learning something as to the probable 

 cause which gave rise to this ver\' striking peculiarity, and should esteem the 

 opinion of other Malacolcjgists who are interested in the members of this 

 Uenus.
