The distribution and preferred situations of 7 species of Mononchida were studied at 28 sites with a variety of forest, grassland and moor soils in the moist temperate climate near Paris, France. By using factor analysis, the relationships between the biotopes studied and between biotopes and species are displayed. By analysis of the relative abundance of the species collected in the different soils it has been possible to particularize progressively groups of species in the humus succession Mor, Moder, acid Mull, earth-Mull and calcareous Mull corresponding respectively to podzol or podzolic soil, leached brown soil, brown soil, calcareous brown and rendzina, raw soil. Data on numerical dominance in the co-habitation of some species within groups may be interpreted as indicating the nature of the soil and possibly its modification.
