“This species is an offshoot of BH. levis Pfr., from which it 
differs by its small, and much heavier shell, fewer whorls con- 
spicuous peristome and narrower, fewer and less interrupted 
banding of a paler tint.’’—Dall, Phila ac pr 1900: 100, t 8, f 3. 
2221 Epiphragmophora areolata 
Under Helix.—‘‘Shell perforated, orbicularly conoid, striated, 
shining, white, variously ornamented with revolving interrupted 
reddish lines; spire depressed conoid; whorls five, rather convex, 
the last scarcely descending, somewhat convex at base; aperture 
roundly lunar, smoky within; peristome acute, somewhat thick- 
ened within, its columellar portion slightly arched, dilated, re- 
flected, with one tooth-like callosity (sometimes wanting), and 
almost covering the umbilicus. Greater diam. 26, lesser 23; 
height 18 mm,

2222 Epiphragmophora Catalinze 
** ‘Helix tenuistriata’ W. G. Binney (as mutation of H. Gabbi), 
Land and fresh-water shells of North America, part 1, page 175, 
f 805, 1869; not of A. Binney,.1842. 
‘‘Arionta Gabbi, W. G. Binney, U S Na mu b No. 28, 148, f 130, 
1885. 
“This form was collected on Catalina Island by H. Hemphill, 
and, while obviously a member of the Gabbi-facta group, seems 
perfectly distinguishable from the other members of that group. 
There is a very large series of Gabbi and facta in the collection 
of the National Museum, and, notwithstanding their variability I 
do not find any specimens which are not readily referred to one 
or the other, and none intermediate between these and cataline. 
The name tenuistriata had previously been used specifically by A. 
Binney, and was repudiated for this shell by his son. As the orig- 
inal tenuistriata A. Binney has never been identified, and in the 
case of the present species the name would have to rest anony- 
mous, it seems better to apply a local name to it which is free from 
any uncertainty. It has a small deep umbilicus partly shaded by 
the reflected pillar lip and a broadly reflected peristome, the ends 
of which upon the body are not approximated. It measures as 
follows: Alt. of shell 7, diam, 12, diam. aperture 4.5 mm. There 
are 5% rounded whorls and the entire shell is finely spirally 
striate. It is also found fossil on Santa Barbara Island, but the 
fossil specimens are often considerably larger than the largest
