摘　　要：运用扫描电镜观察了圆顶珠蚌、褶纹冠蚌、背角无齿蚌、卵形尖嵴蚌及河蚬的鳃表面纤毛的分布、排列方式及细微形态结构。结果表明 :这 5种蚌的鳃表面都有前纤毛、侧纤毛和前侧纤毛。此外 ,仅在河蚬鳃表面前纤毛和前侧纤毛之间 ,观察到一种新的纤毛结构———前触毛。The ultrastructure of ciliation on gill surface of five species of Eulamellibranchia is studied with scanning electron microscopy.The results show that the gill surface of all five species have frontal cilia,lateral cilia and laterofrontal cirri.In addition,a new structure,frontal cirrus between the frontal cilia and laterofrontal cirri,is found only on the gill surface of Corbicula fluminea.It may be related to taking the food particles.
