On Copepoda of the family Corycaeidae in Japanese waters

Abstract

It is interesting to compare the Japanese species with those taken from the other regions of the Pacific, and from the Indian Oceans.The following number of species have been recorded ,from these regions: eighteen species from the Ceylon Pearl Fishery Bank by Thomson and A. Scott (1903); nine species from Bombay by Cleve (1903); eleven species from the Maldive and Laccadive Archipelago by Wolfenden (1905); sixteen species from the Malay region by A. Scott (1909); twenty species from the Christmas Island, Indian Ocean by Farran (1911); twenty-seven species from the Indo-Pacific by M. Dahl (1912); four species from the Suez Canal by Gurney (1912) ; twenty-four species from the Great Barrier Reef by Farran (I9:)6); eleven species from the Indian Ocean by Sewell (19/17); twenty-one species chiefly from the Pacific Ocean by Wilson (1950); two species from the San Diego region by Esterly (1905); one species from the northeastern water~ of the North Pacific by Davis (1949).
