This study is based on a collection of marine euthyneuran mollusks made by the second author at Eniwetok Atoll , Marshall Islands, during February- April, 1960. Seventeen species were collected, of which 5 are described in this paper as new species. The new species are: Haminoea musetta, H. linda, Chromdoris briqua, Herviella mietta and Onchidella eveltnae. Of the other 12 species, the distribution of 7 of them extends eastward from the western Indian Ocean (2 also occur in the Red Sea) to Eniwetok or farther east; 2 species are circumtropical or circumsubtropical; 2 species are known only from the western Pacific; and 1 species occurs from Eniwetok westwards into the eastern Indian Ocean. The relative uniformity of the western Indopacific reef fauna is indicated by the fact that 9 (or over 50%) of our species are known to range from the western edge of the Indian Ocean to the western or central Pacific. The genus Herviella seems to be confined to the western Pacific. Thenotogaeic occurrence of an Onchidella with a ventral recurrent limb of the kidney and a cuticular stylet in the diverticulum of the penial pouch is remarkable.
