[?] Sub-Genus PUTILLA, A. Adams. 

 P. Zool. 8., 1867, type P. lucida, A. Adams. 



Putilla has been referred, possibly correctly, to the family 



Eulimidce. 



The three species described by A. Adams, Ann. Mag. VI, 1870, 

 from Suez, as " Rissoella sp." seem to me to belong to' this 

 group ?
