width of the canal, and, curving a little upward, forms a slight notch before 
joining the columella. The edge of the lip is rounded and crimped by the ter- 
mination of the revolving threads. Columella with a slight sigmoid curvature 
and an inconspicuous layer of enamel. Suture distinct, undulating, slightly 
channelled, The concave subsutural band occupies about a third of the width 
of the upper whorls, and is crossed by fine indistinct lines of growth. Con- 
spicuous, rather broad, angular, oblique ribs cross the whorls, scarcely evident 
on the subsutural band, but rise somewhat abruptly on its lower edge, forming 
a sharp shoulder at the periphery. There are eleven of these ribs on the 
body whorl, reaching to the base of the canal; these, with their equally broad, 
concave interspaces, are ornamented with about twenty-five conspicuously 
raised, uniform, rounded threads, pretty regularly separated, but a little 
crowded on the anterior end of the canal. On the penultimate whorl there 
are six of them, the first just above the shoulder and the last just above the 
suture. Lines of growth very indistinct. Nucleus small, shining, consisting 
of three and a half regularly coiled whorls, the lower one ornamented with a 
peripheral keel. The entire surface of the shell is covered with minute gran- 
ules, closely crowded except on the nucleus, where they are somewhat scattered 
and discernible only under a high magnifying power. 
Length, 15 mm. ; breadth, about 6 mm. ; length of aperture, about 7 mm. ; 
breadth, about 2 mm. 
I can find no description nor figure that bears any resemblance to this very 
elegant species.
