摘　　要：利用活体观察、蛋白银染色技术对淡水腹毛目纤毛虫—锈色尖毛虫 (Oxytricha ferrug-inea Stein,185 9)的青岛种群之活体形态学及纤毛图式做了研究。其特征如下 :虫体浅黄褐色 ;表膜下颗粒为铁锈色 ,聚合成组并作纵向不规则排列。口围带平均小膜数为 35。额、腹、横棘毛为典型8∶ 5∶ 5方式排布 ;尾棘毛恒为 1根。背触毛 5列 ,其中 4列完整 ,1列不完整。伸缩泡位于体左侧前1/ 3处 ,具两根收集管。与相近种比较表明 ,O.ferruginea与前人所报道的另一淡水种 O.aerugi-nosa极可能是同一种 ,因此本文建议将两者合并。The morphology and infraciliature of a hypotrichous ciliate, Oxytricha ferruginea Stein, 1859, collected from a freshwater pond in the Baihua Park in Qingdao, China, were investigated and observed by protargol impregnation method. The results showed the following characteristics: body elongated elliptical in outline, yellow brownish in color, with rusty cortical granules; adoral zone of membranelles composed of 30~40 membranelles; constantly 1 caudal cirrus and 5 dorsal kineties; contractile vacuole in standard position and with two collecting canals; fronto ventro transverse cirri arranged in 8∶5∶5 mode. Compared with other related species, Oxytricha aeruginosa Wrzesniowskiego,1866 was probably conspecific with this species.
