New England. 

 atlantis sordida 



liberta rugosioides 



tristis 

 Three of these species have long been known from New 

 England. Atlantis has heretofore been confused with tristis 

 in most collections. The standing of rugosioides is doubtful, 

 and it will very likely prove to be only an aberrant sordida. 



New Jersey — Pennsylvania. 

 atlantis frondicola bidentata 



liberta harperi excavata 



sordida subcostata 



tristis 

 Here are all the New England species — rugosioides excepted 

 ■ — plus two others, which are more or less common residents 

 of this region. The species in the last column are South 

 Atlantic Coast forms whose occurrence so far north is excep- 

 tional, or perhaps accidental.
