grows most luxuriantly in damp places all over the island, 

 and few plants that 1 have examined at the right season of 

 the year have been without one or more of the Vertigos. 

 This species is referred by Jeffreys to Vertigo edentula, Drap., 

 of Europe.

= lubrica, Miiller. 



= lubricoides, Stirapson. 



= Morseana, Doherty. 



This widely distributed species occurs, but not very abundantly, in 

 all the localities I have examined, generally under stones or 

 logs, often in very exposed situations. 



27. Succinea rusticana, Gould, Proc. Bost. Soc. N. H., II, 187. 



(Dec. 1846). 



The three species of Succinea here recorded seem to be distinct^ 

 although it is not easy, to my mind, to distinguish between 

 the young specimens. Ruslicana has only occurred to me 

 at Comox. 



28. Succinea Nuttalliana, Lea, Proc. Am. Phil. Soc, II, 32. (1841). 



Common at Victoria. 



29. Succinea Oregonensis, Lea, Proc. Am. Phil. Soc, II, 32. (1841). 



Common at Victoria. These three Succineas occur throughout 

 the "Pacific province." 



30. Onchidella borealis, Dall, Am. Journ. Conch., VII, 135. 



(August, 1866). 



This species is common near Victoria on rocks close to high water 

 mark, but is very likely to escape notice unless specially 

 sought for. It was found by Dall from Alaska to Vancouver 

 Island.
