7 Bland entertains doubts if the species referred to inornaia by Binney, is identiail with 

 Say's species of that name. 



8 This is Dr. Binney's "Helix libera of Say." Say's original ligera is a Missouri shell. It 

 does not appear in any public record that ligera has been properly identified or authenticated by 

 reference to oi'iginal types. Mr. Lea appears to have claims to tliis species, strongly sustained 

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



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