The amphipod genus Hirondellea Chevreux, 1889 is a cosmopolitan largely bathyal genus. This paper adds a new species from the bathyal Arabian Sea, Indian Ocean, based on material collected by baited traps at 1182, 1184 and 1864 m off the coast of Pakistan. The species can be distinguished from the most closely allied species, Hirondellea brevicaudata (Chevreux, 1910) by the subacute lateral head lobes, the very weakly cleft telson, and characters of the mouthparts. A key to the ten species in the genus is provided.

A new species of the genus Podoprion is described. The species can be distinguished from the other species in the genus, Podoprion bolivari Chevreux, 1891, P. ruffoi Lowry & Stoddart, 1996, and P. mediterraneum Kaim-Malka, 2004, by the shape of gnathopod 2 propodus, coxa 4, number and size of serrations on pereopod 5 basis, and characters of the mouthparts. Material was collected by baited trap at 1185 m off the coast of Pakistan in the northern Arabian Sea.

AbstractA new species of deep-water crab, Progeryon mus (Geryonidae), is described from Hawaii. The species is allied to P. guinotae from the Indian Ocean as well as P. vaubani and P. mararae from the Pacific, but can easily be separated by various carapace, ambulatory leg, and cheliped characters. Une nouvelle espece de crabe d'eau profonde, Progeryon mus (Geryonidae) est decrite des Hawao. L'esp ece est apparentee a P. guinotae, de l'ocean Indien, ainsi qu'a P. vaubani et P. mararae, du Pacifique, mais peut en etre facilement distinguee par divers caracteres de la carapace, des pattes ambulatoires et des chelipedes.

The identity of the majid species of Paramaya De Haan, 1837, in the Indian Ocean is clarified with the collection of fresh specimens from the Bay of Bengal. Previously identified as P.spinigera (De Haan, 1837) which is known only from Japan, Taiwan, and Korea, the material from eastern India is here referred to a new species, P.mulli sp. n. The new species can easily be distinguished from all congeners by its relatively shorter pseudorostral and carapace spines, more swollen branchial regions, distinctly granulated male thoracic sternum, and the G1 is not prominently curved with the dorsal projection on the sub distal part short and the tip rounded.

Based on a census of the polychaete fauna of the Socotra Archipelago in the Indian Ocean we report here new findings on the genus Syllis Savigny in Lamarck, 1818. These ten species are newly recorded from this area: Syllis alternata Moore, 1908; Syllis bouvieri Gravier, 1900; Syllis broomensis (Hartmann-Schröder, 1979); Syllis compacta Gravier, 1900; Syllis crassicirrata (Treadwell, 1925); Syllis gerlachi (Hartmann-Schröder, 1960); Syllis hyalina Grube, 1863; Syllis lutea (Hartmann-Schröder, 1960); Syllis schulzi (Hartmann-Schröder, 1960); Syllis ypsiloides Aguado, San Martín & Ten Hove, 2008. Additionally, Syllis qamhiyn sp. nov. is described as a new species, characterized by its conspicuously thick and short dorsal cirri filled with a gelatinous substance and reduced number of compound chaetae from medium to posterior parapodia, with enlarged shafts and short blades which become almost unidentate and do not fuse with shafts. Following an examination of the holotype of S. bouvieri, its status as a valid species and not as synonym of Syllis prolifera Krohn, 1852, as considered by some authors (see Licher 1999) is confirmed, and a redescription is included.

A new species of Aloe (Asphodelaceae) is described from Somaliland. It differs from other species in forming large clumps and in having sap that is initially yellow but quickly turns bright red and then dark red or reddish-brown, paniculate red-flowered inflorescences and uniformly coloured leaves with red teeth. Its recognition raises the number of species known from the combined area of Somaliland and Somalia s.s. from 31 to 36. A map portraying species density of Aloe by country, as that genus is now interpreted, shows that Aloe has its highest density on islands in the Indian Ocean but that, within Africa, the greatest density is in countries along the eastern highlands. The data also reinforce the importance of field botanists in determining a country’s known plant diversity.

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

Amongst the unnamed Alcyonaria in the collection of the Royal Scottish Museum, Edinburgh, is a beautiful colony belonging to the genus Cactogorgia, which Mr Eagle Clarke has kindly handed me for identification and description.In 1907 (Trans. Roy. Soc. Edin.) I established the genus Cactogorgia for several small colonies from the Indian Ocean, and referred these to three separate species, viz. celosioides, alciformis, and expansa. Thomson and M'Kinnon, in Trans. Linn. Soc. (Zool.), 1909, have described another species from the Seychelles under the name of Cactogorgia lampas, and the present colony must also be referred to a new species. This we propose to name Cactogorgia agariciformis, n. sp., on account of its very definite mushroom-shape.
