*) Shell long ovate conie: 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 indistinet 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 
orbieular, with two peritremes, 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 l. c.)
