have not yet found the leisure to complete it. I can hardly 
say anything too strong against the systems devised by 
various conchological writers, as they seem to be founded 
on the most arbitrary and artificial characters. I have, in a 
few instances, renamed the orders, not being able to find 
any satisfactory terms in use ; but wherever I have done so 
I have derived the ordinal name from the most characteristic 
genus of the order.
