| Ventral thoracic bloodvessel-patterns were defined in a random sample of 152 living specimens of the Apomatus/Protula- complex. Two main patterns and a derived one could be recognized. Eight characters, often used in Serpulid taxonomy and retraceable in preserved material, were determined too: e.g. presence or absence of an operculum and pattern of thoracic setae. These parameters were correlated to the vascular patterns. It was shown that (a) all operculate specimens possess a vascular system of one main pattern; 86% of those closely studied have "Apomatus-setae" at least from setiger 4 onwards; all have radioles with paired rows of compound eyespots. (b) The non-operculate specimens generally possess the other main vascular pattern; the thorax often has... |
