本文报道了两种新的海洋周毛纤毛虫Zootamarynii sp. nov.和Zootamarynii sp. nov.的生活形态、纤毛器和银线系统。采用活体观察、蛋白银浸渍法和硝酸银银法对王氏虫进行了研究。Z. NII可以通过以下方式识别：海洋动物鞭形虫，柄具交替分枝，体内虫体约（70-80）μm ×（40-50）μm，口缘唇双层，顶端有一个收缩泡，大核C形，盾尾至反口轮带的横列数为22-30，反口轮带至口缘区的横列数为47-58;在第3个毛圈中的三个纤毛排紧密间隔并且彼此平行。由于其交替分枝模式和其它极为相似的形态特征，将以往报道中被错误鉴定的两个形态型与Z. nii：Z. duplicatum sensu Kahl，1933和Zootannium sp. sensu Kahl，1935. Z. wangi的特点是：体内游动体约（65-90）μm ×（45-55）μm，具单层口缘唇，大核J形，腹侧有一个收缩泡，从鞘到反口轮带的横列数为38-50列，从反口轮带到口缘区的横列数为70-85列，纤毛3由两列纤毛组成。这两个物种的详细描述被记录下来。
The living morphology, infraciliature and silverline system of two new marine peritrichous ciliates, Zoothamnium nii sp. nov. and Z. wangi sp. nov. were investigated by living observation, protargol impregnation and silver nitrate methods. Z. nii can be recognized by: marine Zoothamnium with alternatively branched stalk; zooid in vivo about (70-80)μm × (40-50)μm with double-layered peristomial lip; one contractile vacuole apically located and macronucleus C-shaped; number of transverse rows from scopula to aboral trochal band 22-30 and from aboral trochal band to peristomial area 47-58; three ciliary rows in peniculus 3 closely spaced and parallel to each other. Because of the alternatively branching pattern and other extremely similar morphological features, two morphotypes, which were misidentified in previous reports, were combined with Z. nii: Z. duplicatum sensu Kahl, 1933 and Zoothanmium sp. sensu Kahl, 1935. Z. wangi is characterized by: marine Zoothamnium with alternatively branched stalk; zooids in vivo about (65-90)μm × (45-55)μm with single-layered peristomial lip; one contractile vacuole ventrally located, macronucleus J-shaped; number of transverse rows from scopula to aboral trochal band 38-50 and from aboral trochal band to peristomial area 70-85; peniculus 3 composed of two ciliary rows. Detailed descriptions of these two species are documented.
