摘要


Previous workers described eight species of Raja from Taiwan: R. tengu, R. fusca, R. kenojei, R. hollandi, R. macrophthalma, R. olseni, R. acutispina, and R. porosa porosa. In this paper, fishes of this genera were studied in detail. From the result, R. fusca and R. porosa porosa were considered to the the same species of R. (Okamejei) kenojei, R. kenojei, R. hollandi, R. macrophthalma and R. olseni were considered to be the species of R. (Dipturus) kwangtungensis, R. (Okamejei) boesemani, R. (O.) meerdervoortii and R. (O.) hollandi respectively. In addition, a new recorded species of R. (Dipturus) macrocauda was obtained from the northeastern Taiwan waters. A key to the above mentioned species of Raja from Taiwan is presented.
