A nereid worm , Perineresi aibuhitensis has been frequently mis-identified in Korea as P.vancaurica tetradentata or Neanthes virens due to the wide variation in the number and arrangement of paragnaths on its proboscis. In this paper we re-examined ca. 50 worms collected in three intertidal mud flats of the western coast of Korea, and identified them to be P.aibuhitensis , a new record in Korea. We also described the hteronereid of this species and its biogeographical range.

Three species of foreign barnacles were found to invade into Korean interitidal seashores: Balanus amphitrite, B. ebumeus and B. improvisus. The southeastern coast of Korea, near Pusan, is the area where all the specimens of three species were discovered and the populations of these species were well establishe. B. amphitrite is the earliest invader(probably invaded around early 1970's) and most widely distributed in Korea. It is now distributed all around Korea, except the Yellow Sea coast, north of Mokpo. B. improvisus has been successful to expand its reange to the northern part of Korean coast of the East Sea, whereas B. eburneus is restricted to the southeastern coast. B. amphitrite is successfully competing with the native barnacle, B. albicostatus, and in several areas where the mixed populations of the two species occur, the latter species is found to excluded. The Yellow Sea coast has not been invaded by the foreign barnacles, the reason of which is not known.
