Plate 3, fig. 6.
Shell fusiform, varying in ground color from lavender to orange or
even light brown. The shoulder usually is dark brown, while the rest
is lightly dotted with the same color. Extreme apex of nucleus decol-
lated; the first turn remaining is depressed and smooth. Postnuclear
whorls appressed at the summit, strongly, slopingly shouldered. The
shoulder, occupying the posterior half of the space between the sutures,
is marked by about fifteen unequally developed and unequally spaced,
punctate, spiral striations. Anterior half of whorls between the
sutures ornamented with feebly expressed, low, broad riblets, which
terminate at the anterior edge of the shoulder, where they appear as
slight tubercles. Of these, 17 occur upon the last turn. Rostrum
and posterior half of base finely, evenly, spirally Urate, the lirations
being developed at the insertion of the columella. Posterior angle of
aperture acute; columella sigmoid.

Plate 4, fig. 5.
Shell elongate-conic, white, banded and lined with rust brown. A
series of short protractive streaks extend from the summit down on
the posterior fourth of the whorls. The streaks are about one-half as
wide as the spaces separating them. A spiral line of interrupted
dashes extends about the whorls a little posterior to the sutures, while
a broad dull rusty belt covers the anterior half between the sutures
and another, equally wide, the middle of the base. In addition to these
decided markings there are others less strongly denned, all of varying
shades of rust brown. Nuclear whorls decollated. Postnuclear
whorls moderately rounded, appressed at the summit and slightly
constricted at the sutures, marked by low, poorly defined, and irregu-
