摘　　要：作者对钩刺亚册虫（Ａｃｉｎｅｒｉａｕｎｃｉｎａｔａ）的纤毛器和形态结构做了光镜和电镜水平的研究，结果表明：口侧动基索均为单动基列结构，其中ＰＫ１仅后行至胞口后方；背触毛含约１０对紧密排列的毛基体，后端不与其它体动基列相联；射出体除沿胞口分布外，在虫体顶端丛集成盾片状；虫体前部自右向左扭转约１８０°。The morphology, silverline system and infraciliature of a soil ciliate collected from South Africa, Acineria uncinata Tucolesco, 1962 were reinvestigated with light and scanning electron microscopic methods. The results demonstrate that: (1) all three perioral kineties have a structure of monokinetids, of which the PK2 extends only to the anterior 1/3 of the body length, (2) the short dorsal brush consisting of about 10 pairs of basal bodies is not connected with any other somatic ciliary rows, (3) apart from those along the cytostome, the extremely closely set extrusomes are arranged at the most anterior end of the cell and (4) the compressed oral slit are anteriorly“rolled up”and overlapping to the left side forming an oblique spoon-like excavation.The general morphology of this species shows very similar appearances to the original descriptions given by Tucolesco: it has 4-5 kineties (mostly 4!) on the right side (including the 2 perioral kineties), usually 4 (seldom 5) unciliated left kineties (including the dorsal brush and perioral kinety 1) but constant two macronucleus segments which are sometimes very closely connected together. It is still unclear yet whether the short slit-like cytostome is really restricted to the rolled up anterior end (only) as the original author reported, this character could not be confirmed in our observations.
