pointed end of foot projecting far beyond mantle posteriorly; 
rhinophores short and stout, lamellate, with over 20 transverse 
lamellz; branchie entirely retractile, arranged in the shape of a 
horseshoe, not entirely surrounding the anus, which is produced 
into a truncate cone; branchial plumes 12, simply pinnate, some 
of the posterior plumes bifid; oral tentacles short, wholly con- 
cealed under the mantle; eyes apparently absent. Mantle bril- 
liant purple, with a yellow margin (continues in front and be- 
hind), and 3 longitudinal yellow stripes; the yellow of the margin 
is really bright orange, bordered with white; the median yellow 
stripe begins a short distance before the rhinophores, and runs 
between them; rhinophores dark purple; foot white with a pur- 
ple tint, or quite purple when contracted after death; the end of 
foot is purple with a dorsal longitudinal orange stripe. The pur- 
ple color does not dissolve out in formalin.’’—Cockerell, Nautilus

F. W. Bryant, Nautilus 16:70. Bluffs north of Ensenada, 
Lower California. Also near Wilmington, Los Angeles Co., Cal. 
(Hemphill). 
Much depressed, the alt. of shells with an equal number of 
whorls being less than 2-3ds that of Binney’s species. The diam. 
is correspondingly reduced. The aperture is less round. A spec- 
imen measures alt. 11, diam. 27 mm.

“Shell of medium size, elongate-conic, white, variously band- 
ed, or uniformly chocolate brown. Nuclear whorls mammillate, 
smooth. Post-nuclear whorls slightly rounded, ornamented 
axially by a few broad, depressed, almost obsolete ribs which are 
best seen near the summit of the whorls, and many irregular, 
more or less deeply impressed striations, which extended almost 
undiminished to the umbilical region. The spiral sculpture how- 
ever is more conspicuous than the axial, and consists of deeply 
impressed lines which are more closely placed and less strongly 
developed near the summit of the whorls than at the periphery, 
grading gradually in this respect between these two regions. 
Sutures simple, well marked. Periphery and base of the last 
whorl well rounded, the latter ornamented by spiral sculpture 
similar to that between the sutures, but a little more daistantly 
spaced and more strongly impressed. Eighteen of the spiral lines 
appear between the sutures upon the penult whorl and 10 upon 
the base. Aperture large, oblique, decidedly effuse anteriorly; 
posterior angle acute, peristome continuous; columella strong, 
short, somewhat twisted and slightly revolute. The type has 7 
post-nuclear whorls and measures: long. 6.3, diam. 2.5 mm.’’-—
