Remarks. The basal sculpture is somewhat similar to that of arifca Bartsch, but the umbilicus is not bounded by a ridge with which the oblique lirae anastomose. Here the lirae are subparallel and run direct to the inner lip. Cochliolepis planulata (Sow.) Cyclostrema planulata Sowerby, 1892, p. 46, pi. 2, fig. 49. Discopsis planulata Bartsch, 1915, p. 171.

Main lirae 3-4 at start of 1st postnatal whorl, 5-6 on-shell 2 mm. diam., increasing to 7-8 on larger shells; number of intermediaries very variable, One of the lirae near the suture (Bartsch said 4th lira; I prefer to call it 1st main lira) forming a shoulder, which in spite of Bartsch calling it 'strong' does not show on the profile of the outer lip in his fig. 5. Retractive growth-lines better marked between suture and this lira than on rest of whorl, often almost forming pliculae. Lirae often somewhat beaded. The undulations on the peri- pheral keel {africana) are of course merely due to beach wear, as is shown by the Muir Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
