With the previously reported 10 species from these areas, the total 18 species are listed and an illustrated key is provided. KEY WORDS: Thalassinidea,Anomura, Decapoda, Ulreung Island. The thalassinidean and anomuran fauna of the Ulreung Island has been poorly known and 10 species have been reported from Ulreung and Dogdo Islands (Kim, 1973; Kim and Choe, 1981; Kim, 1985). In the present study, we prepared an illustrated key to thalassinideans and anomurans from the areas of the Ulreung and Dogdo Islands. On the basis of the materials collected during the periods from July 1989 to November 1991,18 species were included in the key. Of these, 8 species were newly recorded from the areas of the Ulreung and Dogdo Islands. The Material Examined" section lists all specimens examined and the "Literatures' 1 section in each species lists the references of the species reported from Ulreung and Dogdo Islands. 丁 he classification scheme was based on Bowman and Abele (1982). 포란아목 Infraorder Thalassinidea Latreille, 1831 쏙하목 Superfamily Thalassinoidea 1831 쏙상과 Latreille, Family Axiidae Huxley, 1879 ᄌ(KH 지 ] 과 1.
