Table 1. General distributional data for the polycystine species treated. Geographic distribution areas refer to those indicated in Figure 11. Most abundant species are denoted with bold lettering. Numbers in body of table indicate approximate pecentage contribution to the correponding assemblages; 10: between 5 and slightly over 10%, exceptionally up to 20-30%; 5: up to 5%, usually around 1-3%; A: abundant; P: present. Depths defined are those of peak abundance of the species as derived from various reports, mostly based on materials from the Pacific Ocean. These vertical ranges are probably generally valid for middle and low latitudes, but not for the Subantarctic and Antarctic areas. Species linked to graphics.
