| 内容記述 | The flying fishes appeared in the natural food of the skip-jack, tuna, marlin dolphin, etc. caught in southern sea of Kyushu are treated on this paper. The materials have been continually collected from the summer of 1949 by the Niishiomaru and the Hayatomaru of our college, and some fishing boats of Makurazaki. Till the summer of 1950, both species were perceived among them. The one was Evolantia micropterus (G. and V.) consisted of 3 specimens 40 to 65 mm in length, and the other was Exocoetus obtusirostris Gtr. of 3 specimens 33 to 51 mm in length. The author traced the alternation on the juvenile character of each species accompanied with the growth, comparing them with the numerous materials caught by the Hayatomaru during the summer of the last two years, mainly near Tane and Yaku Islands. |

| 内容記述 | In the former, within 65 mm in length, the lower jaw forms a beak-like extention as in Hemir hamphus, and its proportion to body length decreases gradually with the growth, although its actual length is not so shortened within these stages. Furthermore the posterior part of their dorsal is elevatd as in some species of Tylosurus. But in 86 mm-long specimen, the whole shape nearly agrees with the adult. In the latter, the body is deeper, lower jaw bears an unpaired barbel at its tip, the pectorals nearly transparent, and the ventral is deep black in the younger stages. Within 40 mm long, the length of barbel increases, while in the more advanced stages it does not; then, in about 65 mm long, the barbel dissapears suddenly. In the stages later than 65 mm long, the pectoral turns into dark, and the ventral into completely pale; and in 89 mm-long specimen, the whole shape is nearly identical with the adult. |
