SAS Z736, the holotype of Van Hoepen's P. (Z.) regularis. x 0,92. P. (Z.) zulu includes P. (Z.) charliei (Fig. 47), P. (Z.) regularis (Fig. 48), and P. (Z.) multilineatum (Figs 49-50), all of which are from the same locality as the holotype and have comparable proportions and ornament: the differences cited by Van Hoepen are trivial and within the range of intraspecific variation shown by other peronicera

P. (Z.) zulu differs from P. (Z.) henniei in having a wider umbilicus and more angular whorl section, but it is clear that the latter is derived from P. (Z.) zulu through progressive increase in involution and rounding of the whorl section. In addition, there is a reduction of the lateral keels and progressive serration of the median 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.
