A guide to the freshwater fauna of Ceylon. Supplement 3
This supplement to the “Guide to the freshwater fauna of Ceylon” by A. S. Mendis and C. H. Fernando. Bull Fish. Res. Stn. Ceylon 12, 160 pp. (1962) includes a number of additional records to the fauna and nomenclatural changes designed to bring the names of the Rotifera, and Hydracarina up to date. This latter involves a complete change in naming of Rotifera to keep in line with modern nomenclature synonymizing species where necessary. A major study on the water mites of India by Cook (1067) has necessitated considerable changes in the naming of Ceylonese species. Besides the Rotifera and Hydracarina the Ilemiptera-Heteroptera have received attention as regards the Corixidae and new generic and specific records from published and unpublished material has been included. A major difficulty in studying freshwater animals (for that matter any animals) is the lack of suitable illustrations of local forms. An attempt has been made to fill this gap for the Rotifera and Turbellaria, It is hoped that in future supplements other groups can be similarly dealt with.
