some specimens forming small spines concave beneath. Lat. 16,

2216 E. (Micrarionta) Guadelupiana 
“Shell small, thin, depressed, of a dark-brownish color with 
a narrow reddish band, bordered on each side by a pale streak, 
just above the periphery; spire little elevated, suture distinct; epi- 
dermis strong, in well-developed specimens slightly microscopic- 
ally hirsute; sculpture of well-marked incremental lines, stronger 
on the spire, with occasional microscopic punctations; base more 
or less flattened, the last whorl with the periphery somewhat 
above the middle of the whorl, umbilicus narrow and deep; aper- 
ture sub-circular, very oblique with a strong whitish reflection of 
the peristome, the ends of the lip on the body approximated, 
throat with the bands showing through. Alt. of shell 6, diam. 
10.5, aperture diam, 4.5 mm. 
‘“‘Guadelupe Island, off Lower California, in N. Lat. about 29 
degrees, Anthony, 1896; Snodgrass and Heller, 1899. 
“This very well-marked little species is nearest to EH. Cata- 
line, but is well depressed, with a larger umbilicus and differently 
shaped aperture. It seems to be tolerably abundant, though most 
of the specimens received were defective.’’—Dall, Phila ac pr

2217 Epiphragmophora leucanthea 
“Shell with 51% rather convex whorls; pale lavender, nearly 
white below, with an obsolete white peripheral band, above which 
the whorl is more or less tinged with pale bluish gray, a translu- 
cent band above the peripheral one through which the dark 
brown with which the interior of the whorls is lined may show 
through more or less distinctly; nuclear whorls with wavy radial 
strie, visible under a lens, for a whorl and a half, translucent; 
succeeding whorls opaque, except as stated, polished, with rather 
distinct incremental lines and obsolete vermiculations or mallea- 
tions; base rounded, perforate, with the umbilicus nearly closed 
by the columellar reflection; aperture rounded, the outer lip 
slightly refiected, white, with the throat brown internally; body 
without callus, pillar short, arcuate, with no thickening or denti- 
cle upon it. Major diam. 28, minor 23.5, alt. of shell 20, of aper- 
ture 15 mm. 
Eastern side of Cerros Island, Anthony, 1896. 
“This is evidently a derivative from E. Veatchii, from which 
it differs in the absence of the numerous interrupted brown bands, 
in the usually blunter and lower spire and more distinct and deep- 
er sutures.’’—Dall, Phila ac pr 1900: 99, t 8, f 18, 20. 
2218 Epiphragmophora Orcutti 
“Shell globose, moderately elevated, polished, with nearly 6 
moderately convex whorls forming a dome-like spire; color pur- 
plish brown, lighter toward the umbilicus; a narrow pale band on 
the last whorl bordered behind by a darker brown, poorly defined, 
similar band, both being above the periphery and the suture in the 
earlier whorls being laid on the anterior edge of the darker line; 
nucleus flexuously radiantly wrinkled, pale colored; subsequent 
whorls with fine incremental wrinkles the ridges of which are cut 
by revolving, partly obsolete incised lines; as a rule these lines are 
not deep or continuous, cutting merely the tops of the wrinkles
