ern distribution may not be without interest. Mighels in his 
Catalogue of the Shells of Maine (Boston Jour. Nat. Hist., vol. 1v., 
p. 325, 1843), says: “ This species is plentiful all over the State. 
* * * Jt occurs plentifully at Cape Elizabeth, near the sea” 
“Specimens from different localities differ much among them- 
selves, being more or less curved, or elongated, and some are 
perfectly straight, differing in no respect from U. sinuosa and elon- 
gata of Lamarck, from Germany and France. With Mr. Lea I 
believe them identical.” E. S. Morse, in his “ Observations on 
the Terrestrial Pulmonifera of Maine” (Journ. Portland, Soc. 
Nat. Hist., 1864, pp. 47 and 52), refers to the species as 
common and “found in great numbers in several rocky, 
muddy brooks, near Portland. Have rarely found it in the in- 
terior.” The species is by no means rare in Massachusetts. It 
occurs in Charles river, at Newton, Mass., the shells are here well 
developed; at Lunenburg the shell is found in small brooks and 
the specimens are diminutive in size, scarcely attaining a length of 
2% inches; it is also found at Leominster, an adjoining town, 
and under similar conditions. At the village of Haydenville, a 
part of Williamsburg, in Hampshire county, it is found in the 
greatest abundance, very perfect, and of large size, in the tributaries 
of Mill river ; it is doubtless found in the streams of Worcester 
county, in the central portion of the State. Gould, in his “Inver-
