This species is entered here simply on the strength of the record 

 by Lord mentioned above. I have not myself seen in Van- 

 couver Island any trace of this shell, or indeed of any other 

 Arionta. Arionto Townsendiana, Lea, sp., is, however, com- 

 mon on the mainland of British Columbia, but has not as yet 

 turned up on the island. Dupetithouarsi is a native of Mon- 

 terey, California, and a few other places in the same i^egion.

Isthmia corpulerda, Morse, Ann. N. Y. Lye, VIII, 210, fig. 7 

 (Nov. 18G5). 



Not rare in moss and among leaves. Also found in company 

 with Vertigo sim2jlex, as described below. This is a species 

 that was hardly to be expected in Vancouver Island, its 

 headquarters being in Nevada and Colorado, but I believe 

 my specimens are correctly determined.

= V. tridentata. AVolf. 



Only taken in one locality near Victoria. This was on the margin 

 of a swamp (since drained) about four miles from the city. 

 The specimens were under leaves close to the water's edge. 

 It is an eastern species not before quoted from the Pacific 

 province. Di-. Gwyn Jeffreys considered this species identical 

 with the British Vertigo antivertigo, Di-ap.

I have found this species in moss in many localities, but not 

 y)lentifully. In May, 1887, however, I found it, together with 

 Papa corpulenta, in great abundance on the fronds of a fern, 

 Aspidium munitum. This was at Comox, but I afterwards 

 found it in the same situation in other localities. The Aspidium
