Two species of the genus Melita, Melita setijlagella n. sp. and Melita shimizui (Ueno, 1940), are described from brackish waters in Japan. The former species is distinct in bearing the markedly setose flagellum of antenna 2. The latter has not so far been known from the Japanese waters, and shows variations in some characters, which distinguish the Japanese materials into three morphological "forms". Both species are also discernible from the other species of the genus Melita by the shape of male gnathopod 1 and female coxa 6. The present paper is the second of the senes treating the Japanese melitid amphipods. The previous report dealt with four intertidal species (Yamato, 1987), and this deals with two species from brackish waters, a new species and A1elita shimizui (Ueno, 1940a). Both species are very common in estuaries in Japan and often occur sympatrically. Melita shimizui was originally described as Crangonyx shimizui from two springs on the Liaotung Peninsula of the northeast China (U eno, 1940a, b). Later, Karaman (1981) moved this species to Melita, based upon Ueno's description. This is the first record of this species from Japan. Materials used in this report were obtained from the following localities (Fig. 1). Fujii-gawa (34° 26'N, 133° 15'E): the mouth of the Fujii-gawa River, Onomichi. Nuta-gawa (34° 23'N, 133° 02'E): around Shinkura-bashi Bridge of the Nuta-gawa River, Mihara. Ohta-gawa (34° 24'N, 132° 21 'E): around Yamate-bashi Bridge of the Ohta-gawa River, Hiroshima. Ochiai-gawa (34° 19'N, 135° OS'E): the mouth of the Ochiai-gawa River, near Osaka Prefectural Fisheries Experimental Station, Misaki, Osaka Prefecture, collected by Mr. H. Ariyama. Sozu-gawa (32° 57'N, 132° 33'E): the mouth of the Sozu-gawa River, Mishou, Ehime Prefecture. Shioiri-hama (32° 32'N, 130° 02'E): Shioiri-hama estuary, near the Amakusa Marine Biological Laboratory, collected by Mr. S. Nishihama and Dr. C. Aryuthaka. Nakijin (26° 42'N, 127° 57'E): a concrete ditch poured from a freshwater spring, Shoshi, Nakijin, the Island of Okinawa, collected by Dr. N. Broodbakker. Hinuma (36° 17'N, 140° 29'E): Lake Hinuma, Ibaraki Prefecture, collected by Dr. H. Morino. Garno (38° 15'N, 14P OO'E): Garno estuary, Miyagi Prefecture, collected by Mr. M. Kyouno. The figures of each appendage are depicted from two specimens, which are the holotype and the allotype, or one male and female; the figures from subsidiary specimens are denoted by the numerals within parentheses. Specimens used for figures are numbered, like male (1). Type specimens will be deposited in the National Science Museum, Tokyo, after the study is accomplished. 1) Contribution from the Mukaishima Marine Biological Station, No. 288. Publ. Seto Mar. Biol.
