As the authors have pointed out previously (Kennedy & Klinger 1973:103), S. woodsi may possibly be conspecific with a number of species describedfrom Madagascar. In view of the poor definition of S. woodsi in terms of theholotype, and without being able to study the Madagascar specimens in theirexact stratigraphic context, all comparisons must be viewed with utmost care. S. tenuicostulatum has a slightly more compressed whorl section, but acomparable umbilical diameter (32-37 %),

S. tenuicostulatum has a slightly more compressed whorl section, but acomparable umbilical diameter (32-37 %), and may possibly be a junior syno-nym of iS. woodsi. Differences given by Collignon (1948: 97) pertaining to densityof ribbing and spacing of the submarginal (3) and marginal (4) tubercles seemrather trivial, and, in fact, the specimen of S. woodsi figured by the authorsfrom Durban (Kennedy & Klinger 1973, pi. 3 (fig. 2a-c)) (Fig. 199A-C) is Fig. 195.
