The present article is the report on the Cheilostome Bryozoans collected by .the China’s First Southern Ocean Expedition during 1984-1985 to the waters off the northwest of the Antarctic Peninsula, ranging from 60°S。(latitude) to 66°55′S. (latitude), from 55°W. (longitude) to 69°30′W. (longitude). A total of 500 bryozoan samples from 19 stations was obtained, 420 of which belong to the Order Cheilostomata. The 96 species of the Antarctic Cheilostome Bryozoans described in the present report are grouped into ten colonial forms (table 1 ), namely: encrusting(22 species), celleporiform (5 species}, flustriform (7 species), buguliform ( 19 species), eschariform (1 species), vinculariform ( 6 species), cellariform ( 16 species), reteporiform ( 8 species), catenicelliform (l species) and adeoniform ( 11 species). According to their growth mode, the 96 species of the Cheilostomes are divided into three groups; namely: exclusively encrusting(19 species), exclusively erect (59 species, and intermediate between the two groups (18 species). The latter group includes 16 suberect species which encrust proximlly on the substracta and grow upright distally detached from the?substracta (some authors consider them to be of erect type) and 2 loosely recumbent species (they are considered to be encrusting type by some authors). ?A list of the 96 species and their colonial form and colony growth mode is given. Names ?of the species found from each of 19 stations are also listed (table 2). Descriptions are provided to those species? which .are for the first. time recorded in the waters? off the northwest of the Antarctic Peninsula, and figures and discussions are given for every? species? arranged systematically. Among? the 96 species, four have not yet been determined because of the imperfection of their preservation, namely: Notoplites sp., Camptoplites sp. Cornucopina sp. 1 and Cornucopina sp.2, fifteen species are found to be new to science, and two new genera are ?established:. The descriptions of the new taxa and the four undetermined species are given below.
