The shell described and figured by Reeve as WV. Sturmii of Philippi 
is quite distinct from that well-known American species, which had 
previously been described by Say under the name of Nassa vibex. 
The present species is considerably larger, has a more turreted spire, 
is more coarsely nodose, differently coloured, has more lire within 
the labrum and a conspicuous eallosity above the posterior sinus. 
Reeve describes the columella as ‘but little callous.” This is true 
of the young specimen he had before him. Mature shells exhibit 
a well-developed reflexed yellowish callus, which may be sometimes 
smooth or more or less tubercular. A small transverse tubercle is 
always seen at the upper part. The outer lip is thickened with 
a strong varix, is acute at the edge, and is furnished within with about 
nine short lire. One of the two specimens from Natal presented to 
the Museum by Mr. J. H. Ponsonby is of a rich brown colour, with 
a white line above the middle of the body-whorl and passing up the 
spire above the suture.
