用连续切片法观察了可变石足虫的口纤毛系统。左口多动粒由平行排列的纤毛动粒组成。右口多动体由无规则排列的纤毛动体腹侧部分和纤毛动体背侧双排组成。纤毛后微管的存在与每个激动体，使其能够确定口腔内的多激动体的激动体的方向。本文讨论了口部多动体和口部原基中动体的定向，并与帚虫、草履虫和四膜虫的口部纤毛进行了比较。左口polykinetid被解释为包括adoral membranelles和右口polykinetid被解释为包括stichodyad类型的口旁膜伴随着纤毛场在无政府的安排。本文提出了孔足类、鼻足类和膜口类纤毛虫的亲缘关系。
The oral ciliature of Colpoda variabilis has been examined by serial thin sections. The left oral polykinetid consists of parallel rows of ciliated kinetosomes. The right oral polykinetid consists of a ventral part of ciliated kinetosomes in anarchic arrangement and a dorsal double row of ciliated kinetosomes. The existence of postciliary microtubules in association with each kinetosome makes it possible to determine the orientation of kinetosomes within the oral polykinetids. The orientation of kinetosomes in oral polykinetids and oral primordia is discussed and compared with the oral ciliature of Furgasonia, Paramecium and Tetrahymena. The left oral polykinetid is interpreted as consisting of adoral membranelles and the right oral polykinetid is interpreted as consisting of a stichodyad type of paroral membrane accompanied by a ciliary field in anarchic arrangement. A closer phylogenetic relationship between colpodid, nassulid and hymenostome ciliates is suggested.
