SMITH : NOTES UPON CASSIDARIA AND ONISCIA. I3 



and morion, a narcotic plant. As neither of these words appear 

 to have any significance in connection with either the group of 

 shells or beetles in question, we are at liberty, I think, to make a 

 definite suggestion with regard to their future use. I would 

 therefore suggest that morio be retained for the Molluscan genus, 

 and morion for the group of Beetles, unless the Coleopterists 

 prefer to use a new name, supposing there is no s\-nonym 

 a\ailable. 



The synonymy of Morio is as follows : — 



Morio, Montfort.

Oniscia. 



The term Moriiin, of Bolten, being a mere catalogue name, 

 and unaccompanied by any description, must, of course, be 

 disregarded. In describing Lamhidium, Link places Mormn 

 in the synonymy, and, although it may be equivalent to 

 Lambidinm — and, if so, it is unfortunate that Link did not adopt 

 it — we are hardly in a position to resurrect it ourselves in prefer- 

 ence to Lamhidium. The generic name Oniscia, which has been 

 in general use for many years, cannot be employed, if we pay 

 any regard to the " law of priority." The remaining names, 

 enumerated below, were proposed merely as subgenera, and, in 

 my opinion, are not worthy of retention. Omscidia, a mere typo- 

 graphical error for Oniscia, differs from Lamhidium in having the
