ventricose; the spire also is shorter in proportion, but more thick- 
ened and obtuse; total length one inch three quarters; the whole 
shell is crossed by delicate remote striz, which are minutely 
punctured; the aperture is rather longer than the spire, and toge- 
ther with the inner lip is pure white, the base of the latter is how- 
ever stained by dark chestnut brown; the outer lip is rather inflected 
and is perfectly smooth; this latter character will at once distin- 
guish this species from all its allies; the pillar has four plaits. 
The colour is uniform yellowish white, with slender fulvous, 
transverse lines following the indented strice; these fulvous lines 
are crossed by others more broken and produce a singular resem- 
blance to the mortar divisions of brick work ; adjoining the suture 
is a row of small fulyous spots. 
This shell I only know from a beautiful specimen in the posses- 
sion of Mr. Mawe.

Habit of the last; but is a much smaller shell, having the base 
more contracted, and the tip more acute; the striz also are deeper 
and the punctures larger; it seldom exceeds an inch in length; the 
whole shell is brownish yellow, irregularly marked by white spots 
and blotches, these last spread over the spire, and form an irregular 
band across the middle of the body whorl; the aperture.is white, 
the outer lip crenated, and the pillar has five plaits. 
Ob. Two specimens of this species are in my own collection ; 
but I am unacquainted with its locality,
