KAMAKICHI KISHINOUYE: 
of tlie rectum. Pylorus short, curved, and descending, duodenum more or less 
widened, with three or four pyloric tubes, the shortest of them is at the 
anterior side, and the longest is furthest removed from the pylorus. Intestine 
is narrow and straight. Air-bladder long, more or less spindle-shaped, 
running the whole length of the abdominal cavity. Urinary bladder is 
very long and is found attached to the ventral wall of the air-bladder, 
and above the rectum in the abdominal cavity. Two ureters unite to a 
median canal near the end of the blended kidneys, and open to the posterior 
end of the bladder. 
This species is found chiefly in the clear warm water of the tropical and 
subtropical seas, and is found at the mouth of Tokyo Bay in the east, from 
Sliimane-ken, Kyoto-fu, and at the north of the southern coast of Chosen. A 
few examples are nearly always found in the markets of southern Kyushyu in 
summer and autumn. In the Ogasawara Islands this fish is cut into pieces 
and dried after boiling, or is preserved in hermetic cans. 
Pelagic fish, do not make a school. They feed on pelagic fish and 
calamaries. Voracious and easily attracted with natural or artificial baits. 
Caught with trolling lines, which are dressed with live or salted saurel, or with 
spears after alluring with artificial fish, made of wood or canvas to imitate 
flying fish or its own species. In Kochi-ken and Kagoshima-ken the fish is 
attracted to the shade of a large bundle of bamboo stems or branches of some 
light wood, moored in off-shore grounds, specially constructed for the purpose. 
The colour of the fish is steel-blue in the back, with about thirty dark 
transverse bands, which are distinct in young fishes, and in the adult fish 
when excited. Dorsals, pectorals, and caudal are blackish, while the ventrals 
are dusky. 
A fish about one and half metres in length, and about seventeen kg in 
weight, caught off Hachijoshima in June contained nearly ripe ovaries. Another 
fish of similar size, caught off the Ogasawara Islands in August, 1919 contained 
much more slender ovaries than the preceding. An immature fish, 28 cm in the 
total lenghth was caught by a bonito-angler off' Daiozaki, Miyeken ou Aug. 19, 
1917. 
When speared the fish darts against the bottom, and then floats to the 
surface dead.
