Description Quantitative distribution of meiobenthic faune of Varsova (Bombay, Maharashtra, India) waters was studied at four stations during November, 1979 to December, 1980. The nearshore areas represent a typical polluted environment while stations towards offshore represent relatively unpolluted regions because of their effective dilution and mixing processes. A gradual increase in mean biomass values from nearshore towards offshore was evident. The fauna was constituted mostly by nematodes (52.90%), foraminifera (33.97%), polychaetes (4.05%) and crustaceans (6.15%). Other groups, viz., Radiolaria, Turbellaria, Kinorhyncha, Pycnogonida, Pelecypoda and Gastropoda were occasional inhabitants of the area. During pre-monsoon, higher population density and biomass were obtained from all stations excepting station 2. In monsoon, higher abundance of foraminifera at station 2 contributed to the maximum biomass and population density. Group diversity of meiobenthos gradually increased from nearshore towards offshore. Substratum was clayey-silt generally, except at station 1, where it was almost sandy. At station 1 and 2, a shift in substratum during monsoon was associated with a change in distribution of foraminifera. High values of organic matter were associated with clayey silt bottom
