Number 113 22 November 1967 REVISION OF NEOFIBULARIA (PORIFERA, DEMOSPONGIAE), A GENUS OF TOXIC SPONGES FROM THE WEST INDIES AND AUSTRALIA WiLLARD D. HaRTMAN Department of Biology and Peabody Museum of Natural History, Yale University (Accepted for publication 13 Oct. 1967) Abstract A revision of the sponge genus Neofibularia, known for its dermatitis-producing qualities, is presented on the basis of a re-study of holotypic specimens. Carter's species Fibularia massa is regarded as a synonym of A^. iiolitangere (Duch. &. Mich.), the only species known from western tropical Atlantic waters. A new subspecies of N. nolitangere , with oxeate megascleres, is described as well as a new species, A^. mordens, from South Australia. The relationship of Neofibularia to Biemna is discussed.
