 Plate XXVII. Fig. 12 and 13. 



P. testa elongato-ovali; spira profunde obtusa; apertura li?ieali, labro tumido, reflexo, 

 intus profunde crenulato; columella tribus elevatis plicis. 



Description. Shell elongated oval, spire profoundly obtuse; aperture linear, labrum 

 tumid, reflexed, profoundly crenulated within, columellar with three equal raised plaits. 



This species is unlike any of its fossil congeners. It may be readily distinguished by 

 its profoundly crenulated outer lip, three robust plaits on the columellar, and the aperture 

 which extends from the apex of the spire to the beak.
