Specimen withweak ornament on inner whorls, x 0,57. quently the authors interpret the species on the basis of topotype and more orless isochronous material. As far as attenuation of ornament on the flanks is concerned, the holotypeagrees well with the inner whorls of SAS-Z1875 (Fig. 188) or SAS-Z1138(Fig. 187). The sutures, however, are completely different. The holotype has asuture with long and narrow lobes (Fig. 194A) as compared to the broad and % 250 ANNALS OF THE SOUTH AFRICAN MUSEUM
