Several examples of a Titrbonilla^ which, did it but 

 possess the columellar plait, so characteristic a feature in 

 the PyrgiUincB, would be easily comparable with P. Edgarii 

 Mel v., or P. interstriata Souv. It is eight whorled, white, 

 delicate, longitudinally straightly ribbed, ribs smooth, 

 interstices spirally filostriate, mouth roundly ovate, outer 

 lip slightly effuse, simple, columella straight. Allied to 

 T. {Pyrgostelis) flexuosa Jeffreys, from the Mediterranean, 

 and the recently described T. {Pyrgostelis) Emilice Melv., 

 from Bombay; it is much larger than this latter species, 

 whorls more ventricose, and eight, as against six whorled.
