摘　　要：利用蛋白银、孚尔根和银浸等染色方法对分类上有争议的 E.charon的形态结构和无性分裂过程中皮层的发育分化进行了研究 .E. charon表面有额腹、横、尾部棘毛 10、 5、 4根，背触毛 12列，大核倒“ C”形，小核球形 .E. charon在无性分裂过程中，皮层的纤毛器官多由相应原基发育而成（前仔虫的口围带、口侧膜由老口改组后承继下来） .The development and differentiation of the cortex during the asexual division of E.charon were studied by using Protargol Staining technique,Feulgen nucleal reaction and Silver－ impregnation method.E.charon is characterized by 10 fronto－ ventral,5 transverse, 4 caudal－ marginal cirri and 12 rows of dorsal bristles. The macronucleus and micronucleus are respectively“ C'－ shaped and spherical. During the asexual division of E.charon,almost all of the cortex structures come from related primordia.
