Epiphragmophora — ar- 
rosa, Gld., the Dented 
Snail, shown in Figure 
109, has a fine large and 
rather solid shell. The 
seven whorls, which are 
yellowish brown in color,

cut. The shell is quite rough, with furrows and 
hammer marks, and the umbilicus is distinct, 
though partly covered with the reflexed peristome. 
The home of this species is along the coast of cen- 
tral California, especially in Marin County.

LZ and that is where it now grows to 
Sa perfection. It loves sand and sea 
air, and in summer it may be found near Point P1- 
nos, buried in the sandy soil, underneath the abun- 
dant clumps of Rattleweed. The figure repre- 
sents a large specimen. The shell is thin, delicate, 
and almost globular in form; it is of a light horn- 
color, with a dark band. 
While this typical shell is almost spherical, a 
number of varieties exist, which diverge from the 
typical shape very materially. In fact, it has been 
a disputed point whether they are at all related, 
but as the general trend of modern research in-
