and not the furrows between them; suture distinct, last whorl 
rounded, plump, toward the aperture descending below the pale 
band; base plumply rounded, the umbilicus covered by a reflection 
of the pillar-lip with a minute chink behind it; aperture very ob- 
lique, thickened, whitish, reflected, especially near the pillar; 
throat livid brownish with the bands well indicated. Major diam. 
of large and small specimens, respectively, 24 and 22.5, minor 
diam. 20 and 18.5, alt. 19 and 16 mm.

“This form much resembles in shape the typical E. Kellettii, 
from which it differs in the absence of the yellow flecking and the 
different surface sculpture. E. Kellettii is also a more globose 
shell. The same stock, doubtless, was the origin of both species, 
as well as several others.’’—Dall, Phila ac pr 1900: 104-105, t 8,

Under living and dead Maguey plants (Agave shawii), with 
levis and Stearnsiana, exceeding rare in comparison. Major diam. 
of largest specimen obtained 27, minor 22, alt. 19 mm. This is 
from the type locality of Stearnsiana, which was much more abun- 
dant and differing not at all from San Diego specimens. Orcutt

Hemphill considered this as a variety of Kelletti, and it so ap- 
pears in Pilsbry’s list. 
Under Helix.—‘‘Shell narrowly umbilicated; sub-globose, 
solid, of a dirty white color, irregularly mottled with crowded 
ashy blotches, grouped into revolving series below, with a decided 
wide, brownish revolving band above; with delicate oblique incre- 
mental strie, unequally cut by revolving lines; spire elevated; 
whorls 5, rather convex; aperture oblique, semi-circular; peri- 
stome simple, acute, its columellar termination white, expanded, 
reflected over half concealed umbilicus. Greater diam. 22,1 esser 
17; height 12 mill.

2220 Epiphragmophora crassula 
‘Shell small, solid and heavy, smooth, with 5 whorls; spire 
rather pointed, suture distinct, not deep, last whorl evenly round- 
ed at the periphery; color opaque white with more or less numer- 
ous very pale brown subtranslucent spiral bands, all or part of 
which may be absent; usually there is a peripheral white band 
and between it and the suture one or two translucent bands of 
which the anterior is most constant; from 2-4 narrower translucent 
bands may exist in front of the periphery; the base is rounded, at 
first minutely perforate, later imperforate and sealed by a refiec- 
tion of the pillar lip; aperture rounded, slightly oblique, with a 
solid white, slightly reflected peristome, but no callus on the 
body; pillar broad, short with a conspicuous callosity. Alt. of 
shell 15, of aperture 6, lat. of shell 15.5, of aperture 7.5 mm.
