HELIX. 115 



Adams, DeKay, Linsley, Stimpson. Some of the printed 

 Western catalogues have quoted glaphyra^ but this has 

 arisen from the authors, in ignorance of the foreign origin 

 of Say's shell, endeavoring to fix the name on some Amer- 

 ican shell. Abroad, Ferussac gives glaphyra by name 

 alone in his Tableaux Systematiques, but had never seen 

 the shell. In the continuation of the " Histoire," Deshayes 

 considers glaphyra as the introduced cellaria, though 

 Pfeiffer gives another name to the shell he figures. 



On the other hand, Pfeiffer, in his Symbolae, miscon- 

 ceives glaphyra, and also in his Monographia, but in a let- 

 ter to me he says he now considers the shell described in 

 the last-mentioned work as a variety of inornata Say. 

 Reeve in Con. Icon, doubts Gould's opinion that glaphyra 

 is an introduced species ; he is right in considering his 

 No. 667 a native American shell, because it is inornata, 

 though wrong in applying Gould's opinion to it, as the 

 shell is not mentioned in the Invertebrata. 



There is also additional evidence of tradition in favor 

 of my views, in the fact of Mr. .1. G. Anthony taking to 

 Philadelphia, about the year 1830, a specimen of cellaria 

 found in Providence, R. I., and being told by the Conchol- 

 ogists of the former city that it was glaphyra Say. Dr. 

 Griffith, also, in letters to my father, now in my posses- 

 sion, writes that the original specimen of glaphyra depos- 

 ited by Say in the collection of the Academy was without 

 doubt cellaria, and that it was subsequently broken and 

 thrown aside. This fact destroys the value of a specimen 

 of a young inornata labelled by Mr. Phillips as Say's origi- 

 nal specimen of glaphyra; moreover, Mr. Phillips tells me 

 that he labelled that shell from conjecture.
