76 THE NAUTILUS. 



" Helix subylobosa (?) Binney, Weston, Gould, 172." The late 

 John H. Thomson, in his paper on ' The Land Mollusca of Bristol 

 County, Massachusetts," * says : " I have found large numbers of 

 the bright lemon-yellow variety of this shell on Martha's Vineyard 

 near Gay Head, never on the mainland. Of course introduced from 

 Europe. I tried some in my garden [New Bedford], but the slugs 

 Limax, Arion, etc., devoured the young, and I could never succeed 

 in getting matured specimens." Rev. H. W. Winkley informs me 

 that Rev. Geo. D. Reid has found it in the shell heaps on Martha's 

 Vineyard. 



In 1870 Dr. H. A. Pilsbry records this species from Nantucket. 1 

 They were taken by the late Dr. Harrison Allen at Sciasconset, the 

 four specimens showing the following variations : uniform yellow 

 (var. lutea), four and five bands, and one with five translucent almost 

 colorless bands. During the same year Dr. Benj. Sharp also found 

 it in the town of Nantucket, and later, on the adjacent island of 

 Tuckernuck, all of the uniform lemon-yellow variety. 



In 1904 the writer reported the finding of this species at Chatham, 

 Mass.* Although I am aware that it was collected there long 

 before, it apparently has not been recorded. They were all very 

 pale yellow and bandless, the var. subalbida Locard. Some of the 

 older specimens had entirely lost their epidermis, and were chalky- 

 white, but still as active as their offspring. They were abundant on 

 the steep bluff in front of the light-houses, although I did not dis- 

 cover their presence until a rainy day brought them from their hid- 

 ing place ; not even a dead shell indicated their existence. Mr. 

 L. R. Reynolds informs me that he has collected H. hortensis on 

 Morris Island, a wooded island just south of Chatham. 



There is a tray of specimens in the museum of the Boston Society 

 of Natural History from Provincetown, Mass., collected by Mr. L. 

 L. Thaxter. All are the bright yellow, bandless variety (lutea). 

 A few uniform light yellow specimens were found by Mr. A P. 

 Morse among some cedars near " Old Harbor," Cohasset, Mass. 



The next localities to consider are those of the Cape Ann region.
