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

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



Putilla has been referred, possibly correctly, to the family 

 IluU7nidce. 



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

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

 group ?
