The marine sponge family Raspailiidae Hentschel is revised and referred to the order Poecilosclerida. Of 48 nominal genera, 17 (including one new genus and one new subgenus) are recognised here: Raspailia Nardo, (Hymeraphiopsis, subg. nov.), Ectyoplasia Topsent, Endectyon Topsent, Trikentrion Ehlers, Cyamon Gray, Aulospongus Norman, Raspaciona Topsent, Rhabdeurypon Topsent, Eurypon Gray, Plocamione Topsent, Amphinomia, gen. nov., Lithoplocamia Dendy, Hymeraphia Bowerbank, Ceratopsion Strand, Thrinacophora Ridley, Axechina Hentschel and Echinodictyum Ridley, and three genera are incertae sedis (Tethyspira Topsent, Sigmeurypon Topsent, Cantabrina Ferrer-Hernandez). Fifty-six species are described for the Australian fauna, of which 14 are new to science: Raspailia daminensis, R. desrnonyiformis, R. keriontria, R. melanorhops, R. phakellopsis, R. reticulata, R. wardi, R. wilkinsoni, Ectyoplasia vannus, Endectyon elyakovi, Ceratopsion montebelloensis, C. palmafa, Echinodictyum austrinus, spp. nov. and Amphinomia sulphurea, gen. nov., sp. nov. The phylogenetic relationships and biogeographical distribution of the family are discussed. Tropical north-westem Australian-southem Indonesia has the highest diversity of species in the Indo-west Pacific, and altogether the Australasian region has about 20% of the world's known raspailiid fauna.

Ubiquitination of proteins is a critical step in the controlled degradation process of many polypeptides. Here we show that sponges, the simplest multicellular group of eukaryotic organisms, are also equipped with the ubiquitin pathway. The polyubiquitin cDNA was isolated and characterized from the marine sponge Geodia cydonium. The open reading frame contains six ubiquitin moieties, which are lined up head to tail without spacers. A comparison of the predicted amino acid sequence of the six sponge ubiquitin-coding units with those from other organisms revealed a high degree of homology (> 93%). The ubiquitin gene is expressed to almost the same extent in the two main compartments of the sponge, the cortex and the medulla. However, only in the cortex are detectable amounts of the ubiquitin protein synthesized. The ubiquitin protein isolated from the sponge organism was found to initiate protein degradation in the heterologous reticulocyte system in the same manner as bovine ubiquitin. In vitro studies with dissociated sponge cells revealed that the homologous aggregation factor causes (i) a strong increase in the steady-state level of mRNA coding for ubiquitin and (ii) a drastic increase in ubiquitin protein synthesis, while the homologous lectin failed to display that effect in isolated cells. These data suggest that ubiquitin may play a role in sponge morphogenesis.
