124 Bemarhs on Certain Sjpecies of N. A. HelicidoB. 



In my cabinet are specimens of U. Icevigata from N. Caro- 

 lina, which in every particular — in form, size, color, and sculp- 

 ture — agree with Say's diagnosis of inornata, and are justly 

 comparable, especially as regards the base, with H. ligera. 



Say mentions Pennsylvania as the habitat of his inornata^ — 

 it very probably occurs there, having been found in Maryland 

 and Virginia, and also in Illinois. 



Information afforded to me by Dr. Edmund Raven el of 

 Charleston, throws some light on all this mystery, if indeed it 

 does not explain it. 



Having through Dr. Ravenel cleared up some difficulties 

 about H. avara, I inquired of him as to IT. inornata Say, send- 

 ing him a copy of my Notes on H. glaphyra, and specimens in 

 illustration of my views, viz. H. Icevigata under the name of 

 inornata Say, and H. inornata By. under that of H. glajphyra 

 Say. 



On the 4th Feb., 1860, Dr. Eavenel wrote as follows: — 



" The shell which you have now sent me as H. inornata Say is iden- 

 tical with my shells which I sent to Mr. Say with this name, and which 

 he returned to me without comment. After receiving these shells from 

 Mr. Say, having no doubt upon the matter, I distributed the shell to my 

 correspondents, with this name, and Mr. Lea has recently written to me» 

 that he has specimens now in his cabinet from me, with my original 

 label, H. inornatus. Dr. Binney was with me, after my communication 

 with Mr. Say, and must have seen the specimens in my cabinet, and I 

 suppose that I sent him some. 



"The shell which Mr. Binney has now sent to me as the 'true inor- 

 nata,' is identical with the one you have sent as ' inornata Binney,' and 

 which you believe to be glaphyra. I have not had this shell in my 

 cabinet before. 



" Griffith sent me two specimens many years ago labelled ^fuliginosa, 

 from Pa^ Some years after I received from England a dozen specimens 

 oi cellar ia ; on comparing these with Griffith's shells, I could see no dif- 

 ference. The two specimens from Griffith, and one of the British shells, 

 I sent recently to Mr. W. G. Binney, and he returned them as cellaria.
