The “kichinu” or “kibire, ” Mylio latus (HOUTTUIN), and the “kurodai, ” Mylio macrocephalus (BASILEWSKY), are regarded as the same fish for commercial purposes, because these two varieties of the black porgy look very like, show similar geographical distributions and are equally prized as food fish. They differ, however, in various biological characteristics, of which the spawning season is most noteworthy. While Mylio macrocephalus spawns in spring, Mylio latus spawns in autumn. This suggests the possibility that a new type of fish culture may be developed for brackish waters, in which the young of Mylio latus are stocked in brackish fish ponds in autumn and raised to marketable size by the end of next autumn.
The author carried out some morphological and ecological studies on the young of Mylio latus collected in Fukue Bay, Aichi Pref. in order to get informations necessary for such type of fish culture. The results obtained are as follows:
1. In the young of body lengths 10.7-25.3mm, the ratio of body length to body height become smaller with the growth of the fish, i.e., the body form gradually approaches to that of the adult fish. At the same time, the horizontal patterns on the body side increase in number from one to six.
2. Young “kichinu”were reared in the water of low chlorinities, and their survival rate was recorded (Fig.2). The lower limit of the chlorinity harmless to these fish was about 4‰.
3. When fed with the mysid shrimp, young “kichinu” daily took about 21% as much shrimp as their own body weight at the water temperature of 20°C. The lower the temperature became, the less food they took. At temperatures below 5°C they did not take food. They lay down on their side when exposed to the low temperature of about 2°C for 30 minutes.

The fishes of genus Melamphaës were studied in detail by NORMAN (1929) and PARR (1931, 1933). PARR added four species to the fourteen species reported by NORMAN. There are known Melamphaës cristiseps, M. luguburis, M. nigrofulvous, M. mizolepis and M. biopinosus etc. out of eighteen known species from the North Pacific (mainly off the coast of California, U.S.A). But these species seem not to have been recorded from Japanese waters.
Recently I have examined the specimens of deep-water fishes gathered by our office's resarch boat, No.1 Asahi-maru (56 ton), and chartered boat, No.10 Shinkai-maru (51.6 ton) during investigation of deep-water fishing grounds (500-1000 meters depth) in bottom trawl without otter boards in Tôhoku and adjacent region during July-October, 1951, and made sure the occurrence in Japanese waters of one species M. cristiceps GILBERT (new Japanese name Kabuto-uo) of this genus. Four specimens were collected and they were each almost of the same body length, from 96.5mm to 98.5mm in length without caudal fin. Collected date, location and depth are as follows.
1. (96.5mm) 27 July 1951, off Kesennuma, Miyagi Pref., trawl fishing ground 234. Depth 850m.
2-3. (98.5, 97.5mm) 4 Aug. 1951, off Kuji, Iwate Pref., trawl fishing ground 198. Depth 600m.
4. (97. 5mm) 24 July 1951, off Kinkazan Miyagi Pref., trawl fishing ground 259. Depth 600m. Bad condition.
Body proportions of these specimens were somewhat beyond upper or lower limit of NORMAN'S description, but well agree with GAMAN'S and PARR'S description.
