Iitmy remarks on E. glaphyra Say (Ann. Lye. YI. 352), and 

 in the preceding pages, I have fully stated my reasons for deter- 

 mining that H. IcBvigata Eaf. and H. inornata Say are identi- 

 cal, and that Jl. inornata By. must be referred to II. glaflujra 

 Say. To my mind the evidence is conclusive, but, as already 

 explained, I leave the last named shell in the synonymy of 

 inornata By. 



I would repeat that, confining myself strictly to the descrip- 

 tions of Say, I find that of his inornata apphcable only to the 

 shell known as IcBvigata Raf., and that of glapkyra only to the 

 inornata By. Too much weight has been attached to the locali- 

 ties given by Say of his two shells. He attributes inornata to 

 Pennsylvania, from whence we have now no authentic speci- 

 mens, but the species occurs in Virginia and Maryland, and 

 may reasonably be looked for on the borders at least of the 

 adjoining state. II. glapkyra was found where certainly it 

 was a stranger — no one knows how, or from whence it came. 

 H. cellaria., to which it is referred, inhabits the New England 

 States only, and the facts already stated indicate that Say knew 

 cellaria., and in correspondence did not allude to it as his 

 glaphyra. 



H. inornata By. is a variable species. In many cabinets, 

 both here and in Europe, it appears to be represented by speci- 

 mens from Ohio, which, when mature, are generally by no 

 means " very much depressed," and scarcely " pellucid, polished." 

 I have individuals from IST. Car. and also from Lycoming Co., 

 Pa., which are planulate, pellucid, and with a very brilliant 

 glassy polish. The Pennsylvanian form is small, and the color 

 above is occasionally as dark as in H. fuliginosa. A young 

 specimen with four whorls is much like Say's figure of gla- 

 phyra.^
