"This species is an offshoot of E. 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.

 species is also quoted from Oregon, and is referred by Newcomb

"Though doubtless similar in origin and in coloration, areo- 

 lata is smaller than Veatchii and has a more depressed spire, and 

 on the whole is easily separable from the latter if a good series 

 is compared." — Dall Phila ac pr 1900, 100.

2222 Epiphragmophora Cataljnae 



" 'Helix tenuistriata' W. G. Binney (as mutation of H. Gabbi), 

 Land and fresh-water shells of North America, part 1, page 175, 

 f 305, 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 catalinae. 

 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 x k 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
