Latitude and water depth of samples bearing Krithe capensis, K. spatularis, and Krithe sp. 8. The open arrow locates a possible allochthonous occurrence of K. capensis. species of the Upper Krithe Fauna die out (K. capensis, K spatularis, Krithe sp. 8, and Krithe sp. 9). There is a dramatic increase in the abundance of the genus in the Lower Bathyal Zone with the incoming of four species of the Lower Krithe Fauna {Krithe sp. 4, Krithe sp. 6, Krithe sp. 19, and Krithe sp. 7). Of these, Krithe sp. 4 dominates the Lower Bathyal and upper parts of the Abyssal zones, before it and the three other species are themselves replaced by the true abyssal species at 2 916 m. The most important abyssal taxon is the relatively small, globular Krithe peypouqueti sp. nov. A summary of the species of Krithe that dominate at the various depths off south-western Africa is given in Figure 11. Peypouquet & Benson (1980) recorded the distribution of Krithe and Para- krithe in their transect west of Walvis Bay, but the relative sparsity of data points precludes a detailed comparison with our data (Fig. 15). The overall picture is of a significant increase in abundance across the Neritic/Bathyal boundary, and a decrease in Abyssal depths. The highest values occur within the Bathyal Zone, and in this respect their data agrees with our 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.
