1. Selenites Vancouverensis, Lea, sp. 



Helix Vancouverensis, hesi. Am. 'Phil. Trans., VI, 87, pi. .xxiii, 



f. 72 (1839) = //. vellicata, Forbes. 

 ComiTion and distributed over the whole island. When fully adult 



the peristome is sometimes almost as much depressed above 



as in sportella. 



2. Selenites sportella, Gould, sp. 



Helix sportella, Gould, Proc. Bost. Soc. Nat. Hist., ii, 167. (1846) 



Occurring with the last species at Saanich, Comox and Salt Spring 

 Island, but absent from the district round Victoria. As re- 

 gards its shell it seems abundantly distinct front Vancouver- 

 ensis ; at any rate it is a well marked form, and as such 

 deserves a name. It differs from the last species in being 

 constantly smallei- and more strongly striated, and in having 

 a much more open umbilicus. The dimensions of this sj^ecies 

 and of .S'. ro?/cm«, as given in Binney's Manual, seem to be 

 incorrectly printed. 



3. I'lxMAX AGREsTis, Linne, Syst. Nat. ed. x, I, 652 (1758). 



Introduced, I suppose from Europe, a few yea>s ago, and now a 

 great pest in the Victorian gardens. It has not yet spread fa^^" 

 into the country districts, but no doubt such extension is only 

 a matter of time. 



4. LiMAX HYPERBOREUS, Westerlund. 



I collected some small blackish slugs at Comox in May, 1887, of 

 which I sent some specimens to Dr. W. G. Binney. He re- 

 ferred them doubtfully to this species. In his " Second Sup- 

 plement to the 5th volume ot the Air-breathing Mollusks of 

 the United States," p. 42, Dr. Binney mentions the receipt of 

 a Limax from Seattle, Washington Territory, similar to hyper- 

 horeus in outward appearance and in the dentition.
