We investigated whether Japanese land snails like hydrangea in rain season, which is a typical image for Japanese. Wesurveyed five sites in Uenohara, Yamanashi, central Japan, to collect land snails and record vegetation between May andJuly, 2006. We found more than 400 snails of eight species, most of which were Euhadra peliomphala and Acusta despectasieboldiana. E. pelimphala were found on leaves of hydrangea more frequently than expected from vegetation at the sites,whereas A. despecta sieboldiana were frequently found on other leaves of plants than hydrangea, cherry and Poaceae grass.We also tested whether E. pelimphala prefer hydrangea leaves to cherry or Poacea leaves by experiments in a laboratory, andfound no preference of hydrangea to other species. These findings suggest that the image of land snails on hydrangea duringrain season is a biologically correct image at least for E. pelimphala , but the snail is not necessary prefer hydrangea leavesmuch better to other plants.

The Duskytail Grouper, Epinephelus bleekeri (Perciformes: Serranidae), is recorded from Tanega-shima and Amami-oshima islands and the Yaeyama Islands in the Ryukyu Islands, southern Japan on the basis of six specimens (232.6-581.2 mm standard length). In addition, several records of E. bleekeri by photographs and/or observations from Kanagawa, Kochi, Ehime, Miyazaki, and Kagoshima prefectures are confirmed. Because E. bleekeri has previously been recorded from Taiwan and southward, the present specimens represent the first reliable records of the species from Japanese waters on the basis of collected specimens. Distributional implications of E. bleekeri in Japanese waters are discussed.

Six specimens (189–306 mm in standard length) of the lethrinid fish, Gymnocranius superciliosus Brosa, Béarez, Paijo and Chen, 2013, recently described from New Caledonia, were collected from the Ryukyu Islands, Japan, being the first record of the species from the Northern Hemisphere. Gymnocranius superciliosus is distinguishable from its congeners by the following combination of characters: elongated body (body depth at 1st dorsal-fin spine origin 2.53–3.06 in standard length); villiform to conical teeth on sides of both jaws; forked caudal fin with rounded posterior margins on both lobes, tips slightly pointed; six rows of scales between 5th dorsal-fin spine base and lateral line; no transverse dark brown bar laterally on head or body, except between eye and interopercular flange; blue speckles dispersed on snout and cheek; body scales each with a basal dark brown dot, forming longitudinal rows; reddish color on margins of dorsal, anal, and pelvic fins.
