65. subviridis, Reeve, (f. 176, 177, 178, 358).— C. testa 

 quam G. subviridis magis inflata, pyriformi ; terminis lateri- 

 bus basique carneolis, extremitatibus subobscure purpureo 

 utrinque nebulata, ; umbilico spirali, conspicuo ; labio supra 

 columellas perelevato, acuminato, columellas callo breviore ; 

 hiatu dorsali sublaterali; dentibus magis numerosis (20 et 

 21 circa). 



Note. — Errones, subviridis. The white base and margins 

 and more elongated form of the common species errones 

 would, in general, be sufficient to prevent a comparison 

 with subviridis being even suggested. The latter is much 

 more pyriform, and strongly umbilicated at the spire. 

 There is still a great similarity seen by comparing some 

 varieties.
