Rev. G. W. Taylor, of Victoria, B. C, lias sent ine H. fidelis, 

 H. germana, P. striatella, M. Vancouver ensis, 31. Voyana, 

 H. arborea, and C. fulvus, found in that vicinity." 



There is also a Hyalina near H. viridula (31ke.) or new. 

 H. indentata (Say.), or H. subrupicola, Dall, is also to be 

 expected from near latitude 49°, as a circumpolar or boreal 

 American form. 



Ariolimax Californicus, J. G. C. 



This great slug, apparently identical with the coast spe- 

 cies, is common up to Alta, Placer County, at 3,700 feet. 

 From its yellow color and auriferous home, it is called 

 "Golden Slug." The abundance of some kinds of land 

 molluscs has attracted the attention of the miners at one 

 locality, called " Sing Canon," in Plumas County. There 

 is also a ' ' Snail Canon " about five miles south of Alta, be- 

 yond the American River. From the description of the rocks 

 of this place, I suspect the snails are not the shell-bearing 

 kinds, but also "Slugs," which are much more noticeable 

 by miners from frequenting springy ravines where cool and 

 shady in the day-time, while the shelled kinds rarely occur 

 in large numbers together except in limestone caves or 

 ledges, which do not exist there. 



The former $50 coins of California were called "slugs," 

 that is, lumps of gold. 



Patula Mazatlanica, Pfeiffer. 



This Mexican species must be omitted from the Californian 

 list, as the specimens so identified by Vlr. Rowell and my- 

 self on being compared with types by Mr. Binney prove to 

 be a stunted variety of Hyalina conspecta, Bland. 



I here add some notes on a "Supplement to the Fifth Vol- 

 ume of Terr. Mollusks, etc." By W. G. Binney. July, 1883.
