pointed end of foot projecting far beyond mantle posteriorly; 

 rhinophores short and stout, lamellate, with over 20 transverse 

 lamellae; branchiae 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

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 distantly 

 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, somevhat twisted and slightly revolute. The type has 7 

 post-nuclear whorls and measures: long. 6.3, diam. 2.5 mm." — 

 Dall and Bartsch, Nautilus 16:94.
