Based on four male specimens from Sagami Bay, we present a brief description of Paralebbeus zygius Chace, 1997. This is the second record of the species, which is new to the Japanese fauna. All of the specimens were obtained from small chambers in hexactinellid sponges collected more than a century ago. Morphological variations of some important characters are discussed. Une courte description de Paralebbeus zygius Chace, 1997 est presentee a partir de quatre specimens mâles recoltes dans la baie de Sagami. Cette espece, signalee pour la seconde fois depuis sa description, est nouvelle pour la faune japonaise. Les specimens etudies ont ete trouves dans de petites cavites d'eponges Hexactinellides, recoltees il y a plus d'un siecle. Les variations morphologiques de quelques caracteres importants sont discutees.

sampled and preserved in 100% ethanol prior to analyses in the laboratory. The euphausiid crustacean, Pseudeuphausla latlfrons (G. O. Sars, 1883) ap peared to be the dominant species among the stranded animals, comprising 83.5% of the sample. A small number of other zooplankters were associated with the stranded P. latlfrons, including Euphausla glbboldes Ortmann, 1893, Sagltta sp. (? spp.), and several species of hyperiid amphipods (Lestrlgonus spp., Themlsto gra cllipes Norman, 1869), etc. (table I). P. latlfrons is a neritic species of the tropical and subtropical Indo-Pacific and usually inhabits the upper 100 m throughout the

A new species, Alpheus kagoshimanus , collected from considerable depths of Kagoshima Bay, is described and illustrated, including its live colouration. It belongs to the brevirostris species-group. A distinct pterygostomial spine readily distinguishes the new species from all other members of this group as well as from all the known species of the genus Alpheus . Apart from this character, it bears much resemblance to A. acutocarinatus De Man and A. migrans Lewinsohn & Holthuis in having the remarkably long first pereopods and the middorsal carina of the carapace with a small, interrupted tubercle. More slender first pereopods with 2-8 movable spines on the ischium and the longer first carpal article of the second pereopod are the other characters of the new species. Une nouvelle espece, Alpheus kagoshimanus , recoltee a grande profondeur dans la baie de Kagoshima, est decrite et illustree, y compris sa couleur a l'etat vivant. Elle appartient au groupe brevirostris . La presence d'une epine pterygostomienne distincte la distingue nettement des autres membres de ce groupe comme des autres especes du genre Alpheus . Ce caractere mis a part, l'espece ressemble beaucoup a A. acutocarinatus De Man et A. migrans Lewinsohn & Holthuis par les premiers pereiopodes remarquablement longs et un petit tubercule emousse sur la carene mediodorsale de la carapace. Les premiers pereiopodes plus greles, portant 2-8 epines mobiles sur l'ischion et le premier article du carpe du second pereiopode plus long sont les autres caracteres distinctifs de la nouvelle espece.

Two specimens of the nephropid genus Acanthacaris collected from southwest of Kyushu, Japan were recently examined. They proved to belong to A. tenuimana Bate, which constitutes the first record for the Japanese fauna. The present paper presents short notes on these specimens, showing the range extension and some morphological variations of this rare species. The material is deposited at the museum of Shimonoseki University of Fisheries (SUF).
