Seven new species in two genera, Sarcotragus and Bergquistia (Demospongiae: Dictyoceratida: Irciniidae), are described from Jeju Island, Korea. The separation of the two genera was made on basis of morphological evidence in skeletal structure, especially fasciculation of primary fibres and filament thickness. Two new species in the genus Sarcotragus and five new species in the genus Bergquistia are compared with other reported species.

Eleven new species of two genera, Psammocinia and Ircinia (Demospongiae: Dictyoceratida: Irciniidae) are described from Gageo Island, Ulleung Island and Jeju Island, South Korea. The separation of these two genera was made on basis of morphological evidence, especially skeletal structure with foreign debris. Six new species of Psammocinia and five new species of Ircinia were added to known fauna. All skeletal fibres are very irregular.

Twelve new species of two genera Smenospongia and Cacospongia (Demospongia: Dictyoceratida: Thorectidae) are described from Gageodo Island and Ulleungdo Island, Korea. Of these, ten new species of the Smenospongia are distinguished from the other nine reported species of the genus by the skeletal structure and sponge colour. Primary fibres of the genus Smenospongia are mostly dense, dark colour, and invisible inside of fibres, but they are mostly cored detritus and echinated with spicules. Especially, the end of primary fibres at the surface shows densely cored with spicules. All these new species changed the colour. Two new species of the genus Cacospongia are compared with nine other reported species. In skeletal structure, primary fibres of the genus Cacospongia are light colour, visible inside and more heavily cored with spicules and sands. The skeleton of this genus has large meshes. The colour of the genus Cacospongia does not change.

A new genus and two new species of Bathynellacea are described from California in USA. Califobathynella, a new genus, belongs to the subfamily Leptobathynellinae, and is closely related to the genera Parvulobathynella and Leptobathynella but differs from them with respect to labrum, maxillule, maxilla, and male thoracopod VIII. Based on the detailed structure of mouthparts, the phylogenetic relationship of three genera are discussed. The phlogenetic age of the stem species of three genera are estimated at the late Jurassic, based on their phylogenetic relationship and distribution pattern. Two new species, C. noodti and C. teucherti differ from each other in the structure of labrum.

Two new species, Pedetontinus aureus and Pedetontinus rhombeus are described. Pedetontinus aureus is characterized by the peculiar scale pattern and long ovipositor, and Pedetontinus rhombeus by the large body size and field of short suberect setae of article III of maxillary palpus. The genus Pedetontinus amounts to four species including two new species of this study in Korea. Descriptions, remarks and biological notes are given.

Two new species of the genus Luffariella (Dictyoceratida: Thorectidae), L. tubula n. sp. and L. koreana n. sp. were collected from Jeju-do, Korea. These species differ significantly from the previously reported five species in terms of shape and skeletal structure. L. tubula n. sp. has two categories in thickness of secondary fibres which were different from other species. L. koreana n. sp. is very similar to L. variabilis from Tahiti in skeletal structure, but differs in sponge shape with irregular branching and indistinct surface conules. Primary fibres of the two new species are separated from secondary and tertiary fibres.

Two species belonging to the genus Gregarinidra Barroso, 1949 (Bryozoa: Gymnolaemata: Flustridae) were first found in this study from Korean waters. Gregarinidra furcula n. sp. is new to science, and G. incrustans (Silén, 1941) is newly added to the Korean fauna. Species belonging to this genus are primarily distinguished by two characteristics: interzooidal avicularia and marginal spines. The pitchforked spines clearly distinguish G. furcula n. sp. from the other Gregarinidra species, and G. incrustans shows the difference by having blunt spines and short-triangular avicularia. Gregarinidra incrustans was known to be distributed only in Japan until this species was reported from the South Sea, Korea, in the present study. This study provides descriptions of two species with detailed illustrations by scanning electron microscopy, distributional data, and a taxonomic key to the Korean Gregarinidra species. With the addition of two species reported herein, four Korean Gregarinidra are recorded: G. corbula Seo, 1996, G. furcula new species, G. incrustans(Silén, 1941), and G. serrata (MacGillivray, 1869). Finally, Gregarinidra totals 10 species worldwide.

This paper deals with four species of jumping spiders from Hunan province, China. Two new species; Philaeus daoxianensis sp. n. and Simaetha gongi sp. n., two new ones to China; Neon ningyo and Tasa davidi. Diagnostic structures, such as body and genitalia organs, are illustrated to each species. Descriptions and known data of geographical distribution also are given. In addition, detailed comparisons of the new species and its similar species are discussed. Type specimens are deposited in Department of Biology, Hunan Normal University, Changsha, Hunan, China.

Two new species of the superfamily Membraniporoidea, Conopeum hexagonum and Gregarinidra corbulra, are reported from Korea. These two genera are new to the Korean fauna. The former species is characteristic in the shape of zooids and the latter one in the number of spines.

Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.
