THE NAUTILUS. 87 



NOTES ON MOLLUSKS FROM BRITISH COLUMBIA. 



BY A. W. HANHAM. 



Puncturella cucullata Gould. 



My daughter Phyllis took a full-grown living specimen at low 

 tide this season at Maple Bay, B. C., crawling on the under side 

 of a ledge of rock. Previously I had the species only from 

 Departure Bay, where it was taken rarely by dredging in fairly 

 deep water. 



Hemphillia glandulosa Bl. & Binn. 



My acquaintance with this species is very limited. I never 

 met with it during several season's careful collecting in the dis- 

 trict around Victoria, B. C. Here I have taken it twice but 

 only in small numbers by scraping over the dead leaves in 

 small thickets in pastures close to the Corvichan River; in sim- 

 ilar surroundings, further back from the river, I could not find 

 any. With it may be taken Prophysaon hemphilli Bl. & Binn. 

 (abundant), Polygyra columbiana Lea (frequent), and Polygyra 

 germana Gould (occasional). In the thickets back from the 

 river our big slug Ariolimax columbianus Gld. may be found in 

 some numbers. In my garden, the last two seasons, both this 

 slug and P. hemphilli have shown up in great numbers and have 

 done some damage. Another slug perhaps Ariolimax niger 

 Cooper was noticed on Mt. Arrowsmith, Vancouver Island, at 

 an elevation of 4,500 feet, in 1913 and again this year. It was 

 quite rare, however. 



Selenites sportella Gld. 



I took a fine sportella this summer for the first time, although 

 I have often tried to imagine that some of the smaller S. van- 

 couverensis taken were this species. One good specimen and 

 some remains were taken from the cliff a little above high-water
