210 A MANUAL OF AMERICAN LAND SHELLS. 



Helix inornata, Reeve, 1. c, 666, not Say. 



Hyalina Iwvigata, Tuyon, Am. Jouni. Couch., ii, 247 (1866). 



Zonitcs hvvigattis, W. G. Binney, L. & Fr.-W. Sli., i, 287, fig. 515 (1869); Torr. Moll., 



V. 102. 

 Zonites mpnodes, part, W. G. Binney, 1. c, fig. 508. 



Animal : Head and eye-peduncles dark blue ; body and foot pearly 

 white; margin of foot furrowed, furrows meeting over i)osterior ter- 

 mination; caudal extremity bluish above, with a gland. A distinct 

 locomotive disk. 



Fig. 221. I have received specimens from Pennsylvania to Arkan- 



sas, from Illinois to Saint Augustine, Fla, and Mobile. 

 The species may therefore be said to inhabit the Interior 

 z. lawujatus, var. and Southcm Eegions. It attains its greatest develop- 

 ment in the Cumberland Subregion. 



A more globose variety is figured. 



A variety from Columbus, Ga., and Franklin County, Tennessee, 

 Fig. 221J. is more depressed. I formerly erroneously referred 



this form to Z. capnodes. 



I have given the synonymy of this species in full 

 to show under how many names it has appeared. It 



z. icevigatus, var. sccms to havc bccu scut to Fcrussac by Eafinesque un- 

 der the name it bears, though no description of it by the latter author is 

 extant. FcSrussac 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, Dr. Binney evidently refers to it in 

 the Boston Journal as a striated variety of fuUginosuSj and quotes F6- 

 russac's figure. He also suggests its identity with lucubratus. In 1848 

 the first description of the shell was published by Pfeiffer, whom I 

 have given as the authority for the specific name. In continuing ¥6- 

 russac's great work, Deshayes also describes the shell, as does also 

 Pfeifler in the second edition of Chemnitz. It was therefore well es- 

 tablished and universally known by the name of Icevigatus when the 

 " Terrestrial Mollusks " appeared. The name proposed by Dr. Binney 

 would not, therefore, have precedence over Pfeiffer's even had it been 

 an entirely new name. Dr. Binney, however, commits the error of ap- 

 plying to this species Say's name of lucuhrata, though there is no evi- 

 dence of Say's ever having seen the species. On the other hand, I 

 have seen in Mr. Poulson's collection specimens of Iwvigatns labeled 



by Say " Helix , Claiborne, Ala." The label, written, as Mr. 



Poulson assured me, during the last few years of Say's life, shows con- 

 clusively his ignorance of the species.
