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 ferruginea Stein, 1859）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. aeruginosa极可能是同一种，因此本文建议将两者合并。

Abstract 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, yellowbrownish 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; frontoventrotransverse cirri arranged in 8∶5∶5 mode. Compared with other related species, Oxytricha aeruginosa Wrzesniowskiego，1866 was probably conspecific with this species.
