STUDIES ON THE MORPHOLOGY AND INFRACILIATURE OF VORTICELLA CAMPANULA(PROTOZOA, CILIOPHORA, PERITRICHIDA)

The morphology and infraciliature of Vorticella campanula Ehrenberg, 1831 were investigated and described from life and protargol impregnated specimens. Wuhan population of this species is characterized by: body constantly wide-belled shaped with one layer of peristomial lip considerably everted and peristomial disc moderately elevated; one contractile vacuole apically positioned; cytoplasm opaque with numerous lipoid globelet; oral apparatus typical of the genus of Voticella, the peniculus 3 composed of 3 rows of kineties, of which one near the peniculus 2 was stopped at the joint of peniculus 1 and 3, about 1/2 of the two peniculus in length; the longitudinal fibre coarsefibred, sparse, ca 40-50, while the fibre of the peristomal disc net coarse and shows as the spoke-like. Additionally, the taxonomic implication of above features was discussed.
