134 THE CALIFORNIA HELIX. 



a variety of the following, shown in Fig. 123, and 



named Helix [Arum to) Califomiensis, Lea, Cal-i-for- 



ni-en'-sis. 



The original specimens from which this species 



was named, came from Monterey, and it is in that 

 region that it grows to perfection. 

 Such a specimen has a nearly globu- 

 lar shell, quite unlike that of any 

 other of our snails. The shell is 

 rather thin, of a light horn-color 

 mottled with yellow, and is girdled by 

 a narrow brown band. The surface

 species extends as far north as Mendocino county, and 

 that it embraces many forms less globular than the 

 original. 



I have found a few living specimens at Point Cyp- 

 ress, and it is said that it may be found concealed at 

 the base of the shrubby Lupine (Lupinus arboreus), 

 which abounds at Monterey. The diameter is three- 

 fourths of an inch or less. 



Helix (Ariontd) ramentosa, Gld. , ra-men-to'-sa, is 

 considered by Mr. Binney as one of the above men- 

 tioned varieties, though it seems quite different from 

 the Monterey form. , 



The specimens before me were collected in Ala- 

 meda and San Mateo counties, and I have recently- 

 discovered a colony of them living near my house, 

 around an old oak-stump. They resemble the last 

 species in respect to the surface of their shells, for 

 these are cut into innumerable checks, which are 

 shown by a lens to consist of little oblong grains, 

 arranged parallel to the lines of growth. The shell
