*) Shell long ovate conic: very pale brown or dingy white, with nu- 
merous spiral series of small dark brown spots , which are often elongate, 
and which are arranged in inequidistant transverse stripes : with closely set 
rather strong transverse raised lines and indistinct spiral striae , moderately 
crenulate along the suture; apex truncate with the loss of — whorls; spire 
with the outlines moderately curvilinear: whorls remaining after truncation 
four or five, quite convex, with a well impressed suture: aperture ovate 
orbicular , with two perit.remes , of which the outer one is moderately ex- 
panded and reflected nearly into the plane of the aperture; the inner one 
is moderately produced and reflected : umbilicus very narrow, but extending 
through the truncate summit. (Adams 1. c.)
