With 1 Text-Figure and 3 TablesIn January this year, this region was attacked by sudden drop of the atmospheric temperature continuously for about six days.Early morning of January 19, the junior author was awaked by Mr. Y.MAKINO, the head clerk of the laboratory, who found innumerable fishes stranded on the beach near the laboratory on the way of his daily walk.Immediately he went down to the beach with one of the aquarium members to examine those fishes, found that most of them were coral fishes, and began to collect them for further studies.The senior author made a dive in the shallow water.around the laboratory in that afternoon and observed that such tropical fishes as Apogon c_yanosoma BLEEKER, Abudifduf vaigiensis (Quoy & GAIMARD) and Acanthurus bariene LEs-SON were just losing the balance and dying.The collecting of stranded fishes, in morning or sometimes at night, was continued by us together with some aquarium staff members till February 9.The collected fishes were cleaned, measured and sorted carefully every time.Most of collected specimens were nearly perfect in their appearance except for several specimens which were seemingly damaged by kites.In this paper, the list of stranded fishes is given and some comparison with other cases of fish stranding by the cold is made.We are very grateful to Messrs. Y. MAKINO, S. SAKAI, Y. KASHIYAMA and S. MORIYAMA of the laboratory and the laboratory aquarium who kindly helped us collect and measure fishes.We wish to express our hearty thanks to Mr.
