Circumpolar. Common. The specimens T have collected in Van- 

 couver Island are the finest I have seen; larger than any I 

 have taken in England or in Eastern Canada. 



iO. ViTRiNA Pfeifferi, Newcomb, Proc. Cal Acad, Nat. Sci., II, 

 92. (1861) 



Not common, but widely distributed. Occurs usually under stones. 

 I have never found it in colonies like limpida. 



11. Patula striatella, Anthony, sp. 



Helix striatella, A)ith. Bost. Jonr. Nat. Hist., Ill, 278, pi. iii, 

 f. 2. (1840) 



Very common.

Helix asteriscus, Morse Proc. Bost. Soc. Nat. Hist., VI, 128. 

 (1857). 



Not rare at Comox, May 1887, among fallen and decaying 

 leaves. I have not found it elsewhere on Vancouver Island. 

 Occurs also in eastern parts of America.

Zonites Lansingi, Bland, Ann. Lye. N. H. of N. Y., XI, 74, 

 fig. 1, 2. (1875). 



Described from Astoria in Oregon. It is not uncommon in Van-

 next species is the more plentiful.

Zonites Stearnsi, Bland, Ann. Lye. N. H. of N. Y., XI, 7G 

 fig. 3. (1875)
