354 Remarks on Certain /Species of 



H. glajphyra and II. 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. glajphyra in the synonymy 

 of II. cellaria Mull. 



In both works he remarks: "This is the shell which 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, long since induced me to suppose it might be an im- 

 ported species ; and an opportunity of examining a considerable 

 number of specimens of H. cellaria Mull, 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. Birmey, 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 H. inomata Binney is often " taken to be 

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

 latter, being an introduced species (II cellaria Mull.), common 

 only near the sea shore in cellars and gardens, is not found." 



Dr. Gould, in his " Report on the Invertebrata of Massachu- 

 setts" (1841), expresses the same views as Dr. Binney ; he says, 

 " there can be no doubt that the II glaphyra of Say is identical 

 with the II cellaria of Miiller ; a comparison of shells of the 

 same size and growth showing them to be absolutely similar in 

 every respect." 



He adds, " It seems as yet to be confined to the North East- 

 ern and Middle States. The shell which is very commonly 

 found marked as II glaphyra is the //. inomata Say, in an
