Type material.

ZMB 21256, two syntypes; ex Ernst. ZMB 101835a, c, eight syntypes, see remarks; ex Albers coll. Nos 49-55, Gruner leg.

Remarks.

Martens described this taxon on the basis of ten specimens; two young specimens from Ernst, and eigth specimens from the Albers collection and collected by Gruner. Lot ZMB 101835 has been split into four different ones. The specimens figured in Martens 1873 (: pl. 1 figs 4a-b) are ZMB 101835a; this lot contains two shells. ZMB 101835b contains five specimens with a taxon label in Martens’ handwriting, ex Albers collection Nos 56-61, and collected by Gruner. ZMB 101835c has the same data; these six shells had the numbers 49-55 in Albers’ collection. Finally, ZMB 101835d has three shells with identical data, and labelled in the Albers collection 62-64. The total number of shells in lot ZMB 101835 is thus 16 and larger than Martens stated ( Martens 1873: 190). We now assume that Martens-for whatever reasons-did not consider the eight specimens in ZMB 101835b and 101835d when he described this taxon, and exclude these from the type material. The current systematic position follows Richardson (1993).
