1. Eight species of Gigantione have now been described. One was from the north Atlantic, one from the Indian Ocean, two from the south Pacific, and four from the north Pacific. Of these last, G. pratti and G. hawaiiensis are new species. The hosts of the different species have all been in separate genera, with the exception of those for G. giardi and G. hawaiiensis, both of which were in Xantho. 2. Dr. Shiino is carrying out an intensive investigation of epicarids in the Japanese archipelago, and the writer is in the process of preparing a monograph covering the Epicaridea of the northern Pacific (except for those areas and forms near Japan). Therefore, it should be expected that many new species and possibly genera will be found in the Pacific as collecting continues.
