Shell oblong-ovate, pyramidal, of a dull pale-brown colour, with 
opake white, irregular markings on the anterior half of the last whorl; 
three opake white bands ; the two anterior, interrupted and edged 
posteriorly with dark brown coloration, traverse the last whorl; the 
second, arising from the middle of the outer lip in narrow streaks, 
continues along the anterior edge of the volutions close to the suture, 
on to the apex; the third arises at the posterior part of the outer 
lip, sometimes in conjoined nodules, edged anteriorly and interrupted 
by a dark brown colour, passes over the dorsum and continues in 
irregularly broad, even streaks on the posterior margin of the whorls 
on to the apex. [These characters are marked in fine specimens, 
but are sometimes rendered less conspicuous by irregularity in 
the opake white deposition.] Spire acuminated, constituting rather 
more than one-half the length of the shell; volutions nine to ten, 
slightly convex ; aperture straight, moderately wide ; outer lip sharp 
at the edge, converges abruptly to form the channel, a broad promi- 
nent margin externally, within are four, five, or six denticulations ; 
inner lip smooth and shining, within is a little ridge forming about 
six nodules or teeth, and at the outer edge is a rather strong varix 
extending on to the side of the channel, and from the outer side of 
which varix fine striee traverse the anterior portion of the dorsum ; 
channel rather long and narrow, slightly recurved ; peritreme rather 
quadrangular, and of a lilac colour. 
Length, 5°, of an inch; width, 23, of an inch.
