I have given the synonymy of this species in full to 

 show under how many names it has appeared. It ap- 

 pears to have been sent to Ferussac by Rafinesque under 

 the name it bears, though no description of it by that 

 author is extant. Ferussac mentions it by name only in 

 his Tableaux (1821), with no reference, however, to the 

 figure which afterwards appeared (1832) in the Histoire. 

 In 1840, Binney evidently refers to it in the Boston Jour- 

 nal as a striated variety oi fuliginosa and quotes Ferus- 

 sac's figure. He also suggests its identity with lucubrata. 

 In 1848 the first description of the shell was published by 

 Pfeiffer, whom I have given as the authority for the spe- 

 cific name. In continuing Ferussac's great work, De- 

 shayes also describes the shell, as does also Pfeiffer in 

 the second edition of Chemnitz. It was therefore well 

 established and universally known by the name of IcBvi- 

 gata when the Terrestrial Mollusks appeared. The name 

 proposed by Binney would not, therefore, have precedence 

 over Pfeiffer's, even had it been an entirely new name. 

 Binney, however, commits the error of applying to this 

 species Say's name of lucubrata, though there is no evi- 

 dence of Say's ever having seen the species. On the 

 other hand, in Mr. Poulson's collection are specimens of 

 Icevigata labelled by Say " Helix Claiborne, Ala."
