*) Shell much elongated, ovate-conic : with dark brown irregular trans- 
verse bands, which are deeply and sharply undulated on the posterior side, 
and which are sometimes contracted into waving lines, on a ground of pale 
brown : thin ; elegantly sculptured with very regular crowded striae ; with 
the intervening ridges crossed by many microscopic spiral impressed lines ; 
with a crowded sutural series of sharp crenulations : spire long , with the 
outlines moderately curvilinear: apex truncate with the loss of — whorls: 
a little more than five whorls remaining, with a moderately impressed su- 
ture : aperture ovate , rather large and spreading , a little modified by the 
penult whorl : peritreme single , scarcely reflected to the plane of the aper- 
ture, on the left side appressed to the penult whorl: umbilicus small, with 
strong spiral striae. Mean divergence 32°; length 0,82; greatest breadth 
0,45 ; least breadth 0,33 inch. (Adams 1. c.)
