specimens of Patula from Haywards, near S. F. Bay, seem 

 rather to belong to Durantii, as before remarked. 



Specimens collected at Ounalaska by Harford are doubtless 

 the same species mentioned from there by Middendorf, as H. 

 ruderata, Stud. They are scarcely distinguishable from the 

 Cronkhitei. 



The Oregon Helicine Fauna. 



The north-west corner of California is interesting chiefly be- 

 cause it is the beginning of a new Helicine region, Cape Mendo- 

 cino, lat. 40° 30', being the dividing point. Here Rowell found 

 the typical H. fidelis, Gray, with also a subangled black 

 variety, which looks very much like a link between it and infu- 

 mata, as before remarked. It can scarcely be a hybrid, as the 

 two species (?) do not seem to occur together. This species ex- 

 tends north to Vancouver's Island, 600 miles, and inland to the 

 Cascade Range, about 100 miles, but is not found high on the 

 mountains north of the Columbia. Prof. Brewer found the finest 

 I ever saw at Crescent City, Cal., but it is more common north- 

 ward in the rich bottom lands of the lower Columbia and Willam- 

 ette rivers. IT. Oregonensis, Lea, was more probably the young 

 of this than of Dupetithouarsi, which is not found in Oregon. 



From Klamath Co., about lat. 41°, Dr. Newcomb received 

 some bandless Helices with umbilicus closed, referred by him to 

 H. Nickliniana, but they seem more like a distinct species, and 

 may be called an imperforate var. of H. anaehorcta, W. G. B., 

 until we know that species better.* Mr. Rowell received two 

 specimens from " Oregon " (part unknown), which appear to be 

 the same as Mr. Binney's, and are umbilicate. Some have sup- 

 posed anachoreta to be merely one of the bandless specimens of 

 the banded group occasionally met with, but it looks distinct as 

 figured and described, more like the small, var. of Townsendiana. 

 " Widely distributed through California," as reported by Thom- 

 son, " but solitary," might apply to the bandless varieties, though 

 I have not found any of them except very rarely. 



At Crescent City appears the first of H. Townsendiana, about 

 20 miles south of the Oregon line (Kelsey Haven), and Professor 

 Brewer did not find it anywhere inland, though he obtained H. 

 fidelis on the Siskiyou Mountains. The former extends north 

 to the Straits of Fuca, lat. 48° 30', where I found it. It is the 



* The specimens from this point, called " Calif orniensis " by Dr. New- 

 comb in the article quoted, like all north of Monterey, seem rather a form 

 of redimita. Dr. N. had no Monterey specimens when he wrote the first 

 list, as he gives that among his " additional localities." (1. c. ii, 13.)
