摘要
研究扇贝外套腔内栖生的纤毛虫一蠕状康纤虫Cohnilembusverminus（Muller，1786）的形态、核器及纤毛图式。结果显示其口器结构为；M1呈单列结构，约占体长的1／2，M2由4组毛基粒构成，PM起自M2末端，Sc约由5个毛基粒构成。此外，还列表比较了不同作者报导的C．verminus种群及其它6种已知的康纤虫的主要性状特征。
The present paper deals with studies on the morphology, nuclear apparatus and infraciliature of the endocommensal ciliate, Cohnilembus verminus (Muller,1786) from the mantle cavity of a mollusc, Argopecten collected from a cultural pond in Qingdao. The characterizations of verminus-populations and seven known species of this genus are biometrically tabled.The results demonstrate that its oral appratus is similar to that of the other species in genus Cohnilembus: M1 composed of a single row of kinetosomes, and its length about half of body length; M2 made of four groups of kinetosomes; PM beginning at the posterior end of M2; Sc consisting of 5 kinetosomes.
