Five scuticociliates, collected from China, were morphologically studied using standard methods One represents a new member of the genus Falcicyclidium, F. citriforme nov. spec., which can be recognised mainly by a combination of the following characters: usually two macronuclear nodules, buccal field about half of body length, ten somatic kineties, about 22 kinetal units in somatic kinety 1 and n, and excretory pore near posterior end of somatic kinety n. A redescription for Biggaria bermudensis was provided to include the feature of scutica and argyrome based on new isolate, and variations between different isolates were also discussed. The new population of Sathrophilus holtae differs from the type population by two postoral kineties and fewer kinetal units in the scutica. Its stomatogenesis belongs to the scuticobuccokinetal type, which shows similarities with Dexiotricha among loxocephalids. Morphometric data and brief descriptions were supplied for another two species, i.e., Protocyclidium citrullus and Cyclidium varibonneti.
对从中国采集的5种盾纤毛虫进行了形态学研究，采用标准方法。其中一种代表镰状环毛虫属的一个新成员，即柠檬形镰状环毛虫，新种，主要可通过以下特征组合识别：通常有两个大核结节，口区约为体长的一半，十条体动基列，体动基列1和n中约有22个动基体单位，排泄孔靠近体动基列n的后端。基于新分离株，对百慕大比氏虫进行了重新描述，包括盾片和银线系统的特征，并讨论了不同分离株之间的差异。霍氏嗜污虫的新种群与模式种群的区别在于口后动基列数量和盾片中动基体单位数量较少。其口发生属于盾纤口动基列型，与斜头虫类中的右旋毛虫属有相似之处。还提供了另外两个物种的形态测量数据和简要描述，即瓜形原环毛虫和瓦氏环毛虫。
