KAM-UaCHI KLSHKOCYE: 



Known from tbe tropical regions of ludo-Pacific •watei-s. Caught with 

 liai'poous, hand-liues, aud ti-olling lines at the Ogasawara and Kvukjn Islands. 



Voracious fish, resorting to the rocky bottora of coastal Maters in small 

 schools of tens or scores, devouring Caesio, Decaplerus, etc. Not found in off- 

 shore waters. Caught at gi'ouuds about 20-200 m off, with hooks dressed 

 with live baits. Bites hooks readily iu 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 lmsa^•oury, Init others commend it 

 aj delicious. This clifierence of opinion is perhaps due to tlio diöereuce of 

 season in which the fish was tasted. Klüszingee (49) says "selten einzeb, 

 in hohen Meeren, meist tief, kommt selten, herauf. Frisst als LocksiDcLse 

 Clupeiden und kleine Sphyräueu. Fleisch geschätzt."

Kecently Mr. Akira M.^tsumuka of the Anthropological In-titute. of om- 

 University sent me for identification a large vertebra obtained from a shell- 

 mound in Rj'ukyu. The vertebra is closely allied to the 31st vertebra of the 

 present s^Decies, but not exactly, difllring in the shape of the lateral keels, 

 and the neural and haemal gi'ooves.
