44 Remarks on Certain SjMcies of 



expressing liis opinion that IT. glaphyra Say was identical witli 

 H. nitens, meaning H. cellaria. 



An amnsing letter from Mr. J. G. Anthony informs me of his 

 discovery in 1830 of many specimens of II. cellaria, at Pro- 

 vidence, R. I. (a species then unknown to liim), of his visit 

 shortly afterwards to Philadelphia, and exhibition of the shells 

 at the Academy, where they were pronounced to be II gla])liyra 

 Say. 



Mr. W. G. Binney, in his "Kotes on American Land Shells" 

 (Proc. Acad. Nat. Sci. Phila. 1857), considers the testimony of 

 Dr. Griffith and Mr. Anthony conclusive as to the identity of 

 H. glaphyra and H. cellaria, but I must confess that I am by 

 no means satisfied on that point. 



Say died in 1834. I have referred to all that can be cited as 

 evidence of prior date. 



Dr. Binney, in the Boston Journal (1840), and also in the 

 " Terrestrial Mollusks," included H. glaj)hyra in the synonymy 

 of H. celUoria Miill. 



In both works he remarks: "This is the shell whicli was 

 found by Mr. Say in gardens in the city of Philadelphia, and 

 by him described as H. glaphyra. Its restricted habitat in 

 cellars and gardens in the immediate vicinity of maritime 

 cities, loug since induced me to suppose it nn'ght be an im- 

 ported species ; and an opportunity of examining a considerable 

 number of specimens of H. cellaria Miill. brought from Eng- 

 land, enables me to say, that it is absolutely identical with that 

 species. Shells of the same size and growth from the European 

 and American localities cannot be distinguished from each 

 other." 



Dr. Biimey, with respect to the geographical distribution of 

 H. cellaria, states that it inhabits the North Eastern and Mid- 

 dle States, in gardens, and is common in Boston in damp 

 cellars. 



He observes that II. inornata Binney is often " taken to be 

 H. glaphyra Say, by the Naturalists of the West, where the
