KAMAKICHI KISHINOÜYE : 
Known from the tropical regions of Indo-Pacific waters. Caught with 
harpoons, hand-lines, and trolling lines at the Ogasawara and Ryukyu Islands. 
Voracious fish, resorting to the rocky bottom of coastal waters in small 
schools of tens or scores, devouring Caesio, Decapterus, etc. Not found in off¬ 
shore waters. Caught at grounds about 20-200 m off, with hooks dressed 
with live baits. Bites hooks readily in the twilight. When there is no tidal 
current the fish is easier caught. A better catch is expected in the spawning 
season, May and June, though it is caught all the year round. Some 
condemn the flesh of this fish as soft and unsavoury, but others commend it 
a i delicious. This difference of opinion is perhaps due to the difference of 
season in which the fish was tasted. Klunzinger (49) says “selten einzeln, 
in hohen Meeren, meist tief, kommt selten herauf. Frisst als Lockspeise 
Clupeiden und kleine Sphyränen. Fleisch geschätzt.”

Recently Mr. Akira Matsumura of the Anthropological Institute of our 
University sent me for identification a large vertebra obtained from a shell- 
mound in Ryukyu. The vertebra is closely allied to the 31st vertebra of the 
present species, but not exactly, differing in the shape of the lateral keels, 
and the neural and haemal grooves.
