The present paper is the first part of a systematic study of the cirripedian fauna of Chinese waters. The materials based upon were collected from the coastal zone and the shallow waters of the continental shelf of China during the years 1950-1976 by the 1nstitute of Oceanology, Academia Sinica. 1n this paper an account of thirty-one species and subspecies belonging to seven subgenera of the Genus Ba1anus is given. Of these six species are described as new and nine are recorded for the first time from the waters around Chinese 0oasts. Each of the species. is described and illustrated, the taxonomy and nomenclature of some forms, recorded previously as subspecies or varieties of the Balanus amphitrite complex and B. tintinnabulum complex，are discussed. Based on the morphological and ecological characteristics， some of the predominant fouling forms in Chinese waters, i. e. B. cirratus Darwin (recorded previously as B. amplitrite cirratus or B. variegatus cirratus) , B. reticulatus Utinomi (recorded as B. amphitrite communis by authors) , B. uliginosus Utinomi (=B. amphitrite krügeri Nilsson-Cantell),B.albicostatus Pilsbry (=B. amphitrite albicostatus Pilsbry) , B. rosa( =B. tintinnabulum rosa Darwin) and B.volcano(=B. tintinnabulum volcano Darwin),are raised to speies rank, B. albicostatus formosanus Utinomi is regarded as a synomym of B. albicostatus Pilsbry. The type materials of the new species described in this paper are all deposited in the 1nstitute of Oceanology, Academia Sinica at Tsingtao.
