THE NAUTILUS. 75 



"Helix hortensis may be added to this list on the authority of Wm. A. 

 Phillips, Esq." 



Prof. Edward S. Morse in 1864, in his valuable paper, " Observa. 

 tions on the Terrestrial Pulmoniferaof Maine, etc., 1 places the species 

 under the genus Tachea with the following note : " This species has 

 been found in abundance on several islands from Casco Bay to Grand 

 Manan; Mr. Fuller found them on one of the extreme outer islands 

 of Casco Bay in great profusion." 



In 1868 O. A. L. Mb'rch, under Helicogena hortensis in his paper 

 " On the Land and Fresh-water Mollusca of Greenland," ' says : 

 " Dr. Beck writes in his manuscript above this species : ' Wormskiold 

 has told me that he has found on the leaves of the small shrubs of 

 Salix lanatus in the vicinity of the interior of the Gulf of Tgaliko a 

 banded snail not unlike our garden snail. Two years ago (1844?) 

 I obtained a dead specimen from Greenland, probably introduced.' 

 It is certainly found in Iceland." See, also, Morch, "On the Land 

 and Fresh-water Mollusca of Iceland," page 42, of the same journal. 



In 1869 W. G. Binney and T. Bland in " Land and Fresh-water 

 Shells of North America," 3 refer to the distribution of this species 

 as follows : " An European species introduced by commerce (?) to 

 the northeastern portion of North America. It is found on the 

 islands along the coast from Newfoundland to Cape Cod, and on the 

 mainland plentifully at Gaspe, C. E., also along the St. Lawrence, 

 Vermont (?), Connecticut (?), etc." 



The above records give all we know of what may be called the 

 early history of this species in America, and clearly show that at 

 that time its distribution was practically as it is at present. The 

 following records are, therefore, probably only the results of more 

 careiul collecting over the same area. In taking up in detail the 

 distribution of H, hortensis, 1 will commence at the most southern 

 locality and go northward. 



The Connecticut record is very doubtful, being based entirely on 

 J. H. Linsley's Catalogue of the Shells of Connecticut, 1845.*
