摘　　要：对优美盾纤虫二分裂期间的形态发生学进行了研究，其过程为：１）ＯＰ发生于老ＡＺＭ的左后方皮膜深处，其后一分为二并演化为后仔虫的Ａ－ＡＺＭ及Ｂ－ＡＺＭ。在前仔虫，老ＡＺＭ及ＰＭ完全保留并被继承；２）前仔虫另行产生一原基，由其形成一额腹棘毛，在后仔虫此棘毛来自ＯＰ腹侧；３）棘毛原基共５列，此原基先断裂成前后两组，然后各自演化成前后仔虫的额－腹－横棘毛；４）每列背触毛分别产生前、后仔虫之背触毛原基。Wilbert's protargol method was used in the study of morphology and morphogenesis of Aspidisca pulcherrima Kahl, 1932 during its asexual reproducing cycle. The process is: 1) After appearance of the oral primordium (OP), first 3, then 5 thin streaks of cirral anlagen are formed anterior to TC. 2) The kinetosomes within OP assembly into neatly arranged membranelles and thus the new AZM is formed, which is divided later into two parts: A-AZM and B-AZM. 3) The new paroral membrane derived from posterior end of OP while the“buccal cirrus”is formed from the OP-field (as a pouch beneath the cortex). 4) Cirral anlagen generate 8 frontoventral and 5 transverse cirri. 5) In dorsal bristle rows, the 1st-4th new anlage of both proter and opisthe develops in the middle part of the anterior and posterior half of each corresponding bristle row. Each primordia extends forward and backward, taking the place of old structure.
