1 Bland entertains doubts if the species referred to inomata by Binney, is identical with 

 Say's species of that name. 



8 Tills is Dr. Binney's " Helix lisera of Say." Say's oriu:inal ligera is a Missouri shell. It 

 does not appear in any public record that ligei-a has been properly identified or authenticated by 

 reference to anginal types. Mr. Lea appears to have claims to this species, strongly sustained 

 by the early traditions which refer the shell which Dr. Binney calls intertexla to ligera. Say. 



9 O. cellaria has recently been detected at Buffalo by Mr. Wm. W. Stewart.
