Peanorbis exacuous Say. 



Commonly known as exacutus Say, but Dall (32, p. 91) restores the 

 name as originally used by Say. Henderson and Daniels (56, p. 56), after 

 careful consideration, have done likewise. It includes buchanensis Lea ac- 

 cording to Vanatta {fide Simpson) (136, p. 54). 



Peanorbis exacuous megas Dall. 



Planorbis exactions megas Dall, Rep. Harriman Exp., XIII, 1905, p. 91. 

 Type locality : Birtle, Manitoba. 



Peanorbis geabratus Say. 



Haldeman's and Binney's figures do not represent this species, which 

 is entirely distinct from trivolvis. It is not uncommon in Florida and in 

 the United States does not range outside of that state, (Pilsbry, 91, p. 321). 

 Dall (32, p. 86) includes lentus, which was described from New Orleans, 

 but this does not accord with Fischer and Crosse's (^38, p. 65) identification 

 of Say's type. The true glabratus belongs to section Planorbina and not to 

 Pierosoma.
