Plaxori'.iS AXTROsrs Conrad. 



Vanatta has shown (138, p. 138) that as the earliest available name 

 this must take precedence over the familiar P. hicarinatus Say, non La- 

 marck, 1804. 



Conrad's type has disappeared and until topotypes can be obtained, the 

 uncertainty as to whether Conrad's species is typical hicarinahis Say or 

 equivalent to var. aiigistoiiiits Hald. prevents the proper re-arrangement of 

 tiie forms. 



According,' to A'anatta (1. c. ) P. bicarinatns major and bicarUiatns ininor 

 <■'. Beck (Index. Moll., 1837, p. 118) are synonyms of the typical form.
