Hab.—Off Durban, in deep water (Quekett). 
The type of this species figured in the above work, although in fairly 
good condition, does not show all the characters of this interesting 
form. A specimen recently submitted to me from Port Shepstone 
(Burnup), and which Mr. Sowerby has identified as belonging to his 
species, may be thus described. It differs from the type in having 
ten or eleven nodosities at the angle of the body-whorl, and these 
protuberances upon the upper whorls produce a wavy sutural line. 
The body-whorl also exhibits four or five rather indistinct and 
somewhat nodose, transverse, raised, broad, rounded ridges. The 
aperture is white within, the outer lip being much thickened, slightly 
expanded anteriorly, blotched with brown within the margin, with 
a strong tubercular prominence within at the hinder end. The 
columella is covered with a thick brown-stained callus, which is 
broadly reflexed and appressed over the umbilical rimation, and 
thickened into a white prominence posteriorly a little distance above 
the plice. The upper two of these are about equal in size, the next 
one is rather smaller, and the foremost one still less conspicuous. 
Beneath the thick deciduous periostracum, which exhibits distinct lines 
of growth and has a silky appearance in certain lights, the shell is for 
the most part stained with brown, but where the surface is worn it 
is white. 
Since writing the above I have, through the kindness of Professor 
Poulton, had an opportunity of examining the type in the Oxford 
Museum. It is an immature shell, hence the undeveloped outer 
lip. Mr. Sowerby’s figure is far from accurate, the anterior part 
of the shell being represented much too broad, and the body-whorl 
above the columellar folds is too convex. The four or five rather 
indistinct and nodose transverse ridges on the body-whorl are just 
traceable in the type, and the suture of the spire is also wavy. The 
spire is a little flatter than in the present specimen, and the front fold 
on the columella is rather stronger than the second, thus showing that 
these are liable to variation.
