An oligohalobic peritrichous ciliate, Epistylis chlorelligerum Shen, 1980, was collected from a ditch in Hangzhou, China. The morphology, oral infraciliature, and morphogenesis of the species were studied using living and protargol-impregnated specimens. Zooids of E. chlorelligerum are 160-230 × 50-60 μm in vivo, and characterized by green-colored endoplasm containing symbiotic algae. The oral infraciliature presents a well-developed filamentous reticulum linked to the circular fiber of the cytostome; the outer two rows of P3 extend adstomally over P1 and usually enfold it. During binary fission, one daughter cell inherits most part of the old buccal apparatus and the reorganized haplokinety and germinal kinety (Hk' and G'), and new buccal apparatus of the other daughter cell is mostly developed from the original germinal kinety (G) and haplokinety (Hk): new peniculi 2, 3 (2P2, 2P3), new haplokinety (2Hk), and new germinal kinety (2G) are formed from G, while the new peniculus 1 (2P1) and its peristomial extention (2Pk) originate from Hk. The epistomial membrane can be observed until the two sets of buccal apparatus begin to separate from each other.
一种寡盐性波动型缘毛目纤毛虫，即 1980 年由沈嘉瑞在中国杭州的一条沟渠中采集的藻栖内毛目纤毛虫 Epistylis chlorelligerum，本文使用活体和蛋白银浸渍标本对其形态、口围纤毛列和形态发生进行了研究。E. chlorelligerum 的虫体大小为 160-230×50-60μm，其细胞质呈绿色，含有共生藻类。口围纤毛列呈现出发达的丝状网状结构，与口围纤毛环的环纤维相连；外两列 P3 向口部伸展，覆盖在 P1 上，并通常将其包裹起来。在二分分裂过程中，一个子细胞继承了大部分旧的口部器和重组的单联体带（Hk'和 G'），而另一个子细胞的新口部器主要由原始的生殖带（G）和单联体带（Hk）发育而来：新的 2P2、2P3 刺丝体、2Hk 和 2G 由 G 形成，而新的 2P1 和其口围延伸（2Pk）则由 Hk 形成。口膜可以观察到直到两套口部器开始彼此分离。
