| A small Prorocentrum species was found during a pilot taxonomic survey of marine benthic dinoflagellates in the northwestern Arabian Sea, Oman. Based on the study of cells from natural samples and laboratory cultures using light and scanning electron microscopy, this taxon is attributed to the little-known Prorocentrum sipadanense, recorded so far only from East Malaysia. The description of this species has been emended to include details of internal cell structure, composition of its periflagellar area and intraspecific variability in size, shape and pore pattern. Round to oval or ovoid cells of P. sipadanese are surrounded by a prominent marginal ridge and are 17.9–23.9 µm long and 15.0–19.8 µm wide, with a foveate to reticulate thecal plate surface and... |

| A new thecate, photosynthetic, sand‐dwelling marine dinoflagellate, Laciniporus arabicus gen. et sp. nov., is described from the subtidal sediments of the Omani coast in the Arabian Sea, northern Indian Ocean, based on detailed morphological and molecular data. Cells of L. arabicus are small (16.2‐30.1 μm long and 13.1‐23.2 μm wide), dorsoventrally compressed, with a small apical flap‐shaped projection pointing to the left. The thecal plate pattern is distinguished by minute first precingular plate and sulcus, which extends into the epitheca, with large anterior and right sulcal plates. The Kofoidian thecal tabulation is Po, X, 4′, 2a, 7′′, 6c, 6s, 5′′′, 2′′′′. Morphologically, the revealed plate pattern has an affinity to the Peridiniales, and LSU rDNA... |

| Despite its climatic and ecosystemic significance, the coastal upwelling that takes place off Oman is not well understood. A primitive-equation, regional model forced by climatological wind stress is used to investigate its dynamics and to compare it with the better-known Eastern Boundary Upwellings (EBUs). The solution compares favorably with existing observations, simulating well the seasonal cycles of thermal structure, surface circulation (mean and turbulent), and sea-surface temperature (SST). There is a 1.5-month lag between the maximum of the upwelling-favorable wind-stress-curl forcing and the oceanic response (minima in sea-surface height and SST), which we attribute to onshore-propagating Rossby waves. A southwestward-flowing undercurrent... |

| The Sultanate of Oman harbours rich populations of sponges, especially in the four coral reef areas (Musandam Peninsula, Muscat coast & Daymaniyat islands, coasts of Masirah Island, and the Khuriya Muriya Islands). Up till now, apart from a few incidental samples, the sponges of Oman were known only from five dredge stations made by the John Murray Expedition 1933-1934 off the south coasts of Oman, near the Khuriya Muriya Islands, between 13.5 and 1415 m. Descriptions of the sponges obtained in these dredges were published by Burton (1959) and the specimens are deposited in the collections of the Natural History Museum, London. To complement these dredge samples, we recently obtained samples collected by SCUBA and shore collecting, mostly from the... |

| The study of twenty-nine oligochaete samples collected in 1996 by J. H. Stock and J. J. Vermeulen (University of Amsterdam), in the Sultanate of Oman, allowed us to draw up an initial inventory of the freshwater oligochaete fauna of the Arabian peninsula, a fauna totally unknown until now. The 147 specimens examined belong to nine species of four families: Phreodrilidae, Naididae, Tubificidae and Enchytraeidae. The Phreodrilidae (2 species) represent more than half of the total specimens; whilst the rest belong mainly to the Naididae. Two new species of Phreodrilidae (Antarctodrilus arabicus n. sp. and Phreodrilus stocki n. sp.) are described. Both belong to the subfamily Phreodrilinae, until now not reported from north of the tropic of Capricorn. Other... |

| Sixteen species of Pycnogonida are recorded from littoral or very shallow waters (0-3 m) of the coast of Oman. Four species are new to science: A. lagenaria, Ammothella omanensis, Achelia boschi, and Pycnogonum moolenbeeki. Since up to now no littoral Pycnogonida have been recorded from the Arabian peninsula, all other species are new to this region, with the exception of one which was recorded from deeper waters off Oman before. For some of them the range is considerably extended. |

| Comparison of Sollasella digitata Lendenfeld, 1888, up until the present assigned to its own family Sollasellidae Lendenfeld, 1887 in the order Hadromerida, and Raspailopsis cervicornis Burton, 1959, assigned to Raspailiidae Nardo, 1833 in the order Poecilosclerida, leads to the conclusion that both should be considered congeneric and are best assigned to a single genus Sollasella. This conclusion is based on examination of habit and skeletal characters of the type material of S. digitata and both type and freshly collected material of S. cervicornis. The conclusion is strengthened by the discovery of a new species, Sollasella moretonensis n.sp. collected in North Australia (primarily in the northeastern coast, but also an isolated record from the... |

| Recent (1998) collecting off the coasts of Oman in the course of the EC-MAS3 funded ‘Symbiosponge’ project yielded three species of the genus Biemna Gray, 1867 (Demospongiae, Poecilosclerida, Mycalina, Desmacellidae) not previously known from the area. One of these appeared to be new to science and is described as Biemna omanensis n.sp.. Its distinguishing features comprise the possession of oxea megascleres, which is of rare occurrence in Biemna, and a full complement of microscleres including microxeas, sigmas, commata, all of which are divisible in two non-overlapping size categories, and raphides. One of the other two species conformed to an earlier described species Biemna ciocalyptoides Burton, 1959, which was discovered to be a junior synonym of... |

| Several Conus species of the coast of Oman are revised. Conus stocki n. sp. is described from Masïrah Island. For C. ardisiaceus Kiener, 1845, a neotype is designated. A lectotype is selected for C. luctificus Reeve, 1848. C. lischkeanus tropicensis Coomans & Filmer, 1985, has a disjunct range in the Indian Ocean. The recorded distribution of C. parvatus sharmiensis Wils, 1986, is enlarged from the Red Sea to the coast of Oman. c. quasimagnificus Da Motta, 1982, is provisionally considered a subspecies of C. pennaceus Born, 1778. |
