AbstractTwo new Ceriantharia, Pachycerianthus curacaoensis and Arachnanthus nocturnus, both from the Caribbean region, are described. It is recommended to avoid the terms proto- and metamesenteries in taxonomie descriptions. The cnidom of the Ceriantharia is discussed; a subdivision of the spirulae (=b-rhabdoids) and penicilli ( = p-rhabdoids) differing from that of Schmidt (1972) is given. The anoplotelic character of the terminal tube of the penicilli (Schmidt, 1972) is doubted on the basis of light microscopical investigations.
Mainly on the basis of the study of Botruanthus benedeni (Torrey & Kleeberger, 1909) (Botrucnidiferidae), the 2 newly described species (respectively belonging to the Cerianthidae and the Arachnactidae), and of the data available in the existing literature, it is concluded that the Ceriantharia may be subdivided into 2 suborders, for which the names Spirularia and Penicillaria are proposed. The Spirularia include the Cerianthidae and the Botrucnidiferidae. The Penicillaria include the Arachnactidae only. Diagnoses of the newly proposed suborders are given in addition.
