摘要: 原环虫(Archiannelids)中除去囊须虫属(Saccocirrus)等个体稍大外,余均为小型底栖生物(Meiobenthos).1962年以来,我们在黄海青岛沿岸采到5种原环虫.本文第一作者等曾就其中单殖囊须虫(Saccocirrus gabriellae Marcus*)作过初步报告;这里再根据日本北方的色丹岛、美国旧金山和我国黄海等海区标本,以及室内观察结果,对其不同种群间的变异和个体生殖发育情况作新的介述.很久以来普遍认为原环虫是环节动物门的一个纲,系比较原始的环虫.Abstract: This paper presents the results of a study of the systematics and larval developpment of Archiannelids collected from the littoral zone of the Yellow Sea.Five speties belonging to 3 families and 4 genera are identified.Of these,two are new species and two are recorded for the first time from Chinese waters.The Archiannelida are probably an artificial group uniting the Annelids of primitive structure.Most of them are meiobenthos.The Archiannelida form a heterogeneous group of annelids and should be considered as different families of polychaeta.
