	abstract = { A new species of the genus Guitarra (G. laplani) is described from the Gibraltar region (Northeast Atlantic). The type material of the species, G. fimbriata Carter and G. voluta Topsent revised by scanning electron microscopy, and the results compared with descriptions from the literature. The results suggest G. voluta is a valid species and provide grounds for distinguishing two groups of specimens among those described under the name G. fimbriata. The first group is formed by North Atlantic deep specimens matching the holotype of G. fimbriata and is mainly characterized by tornostrongyloid megascleres, the presence of two categories of placochelae, and microspined pseudoisochelae. The second group, with an Indo-Pacific littoral distribution, would correspond to G. bipocillifera Broensted, characterized by oxeas tapering to long points as megascleres, one category of placochelae, and distinctive spiny isochelae. These results illustrate a new example of what was previously believed to be a cosmopolite species, that a thorough reexamination has shown to be a species complex, thus restricting the distribution of G. fimbriata s.s. to the North Atlantic.},

	abstract = {A new sponge species Discorhabdella hindei, is described from specimens found at a depth of 534-604 m off the Mediterranean side of the Gibraltar Strait (Alboran Sea). This species is closer to the New Zealand type species, D. incrustans, than to the other known species of the genus from the Azores, D. tuberosocapitata . The characteristic echinating acanthostyles of this new species closely resemble those found in Oligocene deposits from New Zealand. The similarity between the new species and the fossil pre-Messinian Indo-Pacific species, along with the strong differences from the Atlantic species, suggest a Tethyan affinity for this new species},

The anatomy and cell composition are described and compared to that of species of the other homoscleromorph genus without skeleton, Oscarella, and to genera with skeleton, Corticium and Plakina. The new sponge differs from Oscarella in its morphology, anatomy, and cytology. . An emended definition of the genus Oscarella is proposed. Anatomical and cytological characters carry a high informative content and should be described for a greater number of sponge species.},
