Not common, but occurring in all the localities 1 have searched. 

 It is a much smaller shell than the next species, and is of a 

 richer chestnut color. Specimens usually occur singly, and I 

 have never found more than two under the same log. Golum- 

 hlanus, on the contrary, is generally in colonies. Germanum 

 seems to be a species of limited range, the only locality 

 named in " Binney's Manual " being Astoria, in Oregon.

= H. labiosa, Gould. 



Abundant among leaves and under logs. Occasionally specimens 

 occur with an indication of a ]mrietal tooth. I have twice 

 taken specimens with the shell of a grayish white colour. 

 Occurs fj'om Sitka to California. 



20. Mesodon devius, Gould, sp. 



Helix devia, Gould, Proc. Bost. Soc. N. H., II, 165. ^1846) 



I have only seen one specimen of this species from Vancouver 

 Islanl, and that was taken at Esquimalt, near Victoria. The 

 specimen was sent to Dr. W. G. Binney, who agreed in the 

 identification. Devius is not uncommon in Oregon, and was 

 therefore to be expected in Vancouver Island.

Common in woods. The shell sometimes nearly black, occasion- 

 ally very pale greenish white and almost transi:)arent. This 

 species roams abroad in wet weather in the spring and autumn 

 after the manner of the European Helices.
