Dall, Nautilus 24:111 as Tegula. 
“‘Shell conical, imperforate, black or purplish-black; whorls 6 
-7, concave, longitudinally somewhat obliquely plicated, the plice 
more or less projecting at the suture, and on the edge of the basal 
whorl, producing an undulating or crenulated effect. Otherwise 
sculptured by incremental striz which traverse the surface and 
cross the plice at right angles. Base concave, radiately, closely 
and prominently striated, more conspicuous, flattened, coalescing, 
and sinuously curving at the edge. Commencing at the point 
where the outer lip joins the body whorl, a shallow groove follows 
parallel to the periphery and extends toward the aperture, with- 
out interrupting the basal sculpture. Aperture obliquely sub- 
angulate, black-rimmed and crenulated on the thin edge of the 
outer lip; nacreous, silvery white toward the edge, bright lus- 
trous golden yellow within and around the umbilical region, which 
latter though deeply pitted is not open. Columella white, cal- 
loused, arcuated with a moderately developed rib bounding the 
umbilical depression, and terminating in a single tubercle. This 
rib is paralleled by a shallow furrow terminating in a notch just 
below the tubercle, and by an exterior or outer ridge, part of the 
way double, of a brilliant orange color; this orange-colored rib 
is also exteriorly bounded by a shallow furrow which becomes 
obsolete toward the aperture. The base of the shell otherwise 
exhibits faint revolving sculpture. Dimensions: Altitude, 36 mm., 
diameter maximum, 34 mm. The above combines the sculptural 
features of the Japanese Chlorostomas and West Mexican Uva- 
nillas, more particularly U. olivacea. It is a much handsomer 
shell than the latter and the most northerly form of the group 
yet detected on the west coast.’’—Stearns, Nautilus 6:85-86.
