The present study was performed to elucidate the distribution of protozoans according to the actual conditions of soil pollution around Ulsan industrial complexes, Korea. Samples were collected from the top-soils of 13 localities in eight times during the period from 16 April 1994 to 14 January 1995. As a result of this study, total 11 species of hypotrichous ciliated protozoa were identified and analyzed. These hypotrichs are 6 species of stichotrichine hyporichs ( Keronopsis sp., Pseudourostyla sp., Hoiriiticha syivatica, Hipiosticha multistylata, Hoios-ticha sp. and ParuroleFitus sp.) and 5 species of sporadotrichine hypotrichs (Oxyricha sp., Steinla sp., Histriculus cavicola, Hemisincirra sp. and Gonostomum auiili). Of these 11 species, 4 species (Keronopsis sp., Pseudourostyla sp., Holosticha sp. and Hemisincirra sp.) are reriorted for 1%e first time from Korea. All the sampling localities could be grouped in three zones by the cluster analysis with the abundance and distribution of protozoans. This result is approximately coincide with the ionation by the concentration of heavy metals.

In this study, we present new records to Korea for three ciliate species[Apogonostomum pantanalense Foissner, 2016; Keronopsis polychaeta (Borror, 1966) Jankowski, 1979; Frontonia canadensis Roque and Puytorac, 1972] collected from marine (F. canadensis) and moss-covered soil(A. pantanalense and K. polychaeta) habitats. We examined the morphology of these three ciliates based on live observations and protargol impregnation. The main characters of the three ciliates are as follows: A. pantanalense: cell size approximately $130{\times}45{\mu}m$, tail-like posterior end, and 6 or 7 ventral cirral pairs elongated to transverse cirri; K. polychaeta: size approximately $140{\times}90{\mu}m$ and approximately 18 frontal coronal cirri and 5 transverse cirri; F. canadensis: cell size approximately $100{\times}50{\mu}m$ and approximately 88 somatic kineties, 3 or 4 vestibular kineties, and 5 postoral kineties.
