6 weeks. Also supplementary, single captures were made. 3. Shore and shoreline collectings. We used fine-meshed­net8 made of sieve for aquatic or bottorn-inhabit ing animals. Spilling,floating, and slopping techniques were also applied to extract the coastal and shore-dwell ing faunas. 4. Por collecting by baits and coprophagous materials, we.used meat, bone, and faeces baits in soil traps, sunk and covered with aluminium foils, without any conserving fluids. We emptied the traps daily, occasionally several times per day. - Fallen and decomposing fruits and the underlying soil was also sifted. - Sifting, floating and single collecting methods were also used for the coprophilous faunas of buffalo, elephant, cattle, and goat dungs. 5. Por the several vegetable layers,we applied sweeping nets and beating nets in collecting in the shrub and foliage layers. - Singling was used under barks and in lying trunks. 6. Nocturnal collectings were made with a 300 lumen petroleum lamp with sheet. Also light-traps were used, when electricity was available, with a 200 W bulb. The killing glass contained loose wood excelsior to protect the material, the killing agent was chloroform in a bottom phial. In conserving the collected material, a number of pre­cautions had to be made. On the one hand, tropical conditi­ons delimited the ranges of storing, and on the other, we had to pay attention to the optimal means of future prepa­ration and identification. All conserving methods applied had perfectly served the above requirements. 1. Depending upon the quality of the material, the extracted materials of the Berlese extractors ,the aoil traps and the pre-prepared soil worms were conserved in 70-80 per cent alcohol, together with the Chelicerata, the Crustaceans, the insect larvae, the lower insects, Epheraeropters , the Trichopterans all insects collected by light (except the Co­leoptera, the Rhynchota, and the small Orthopterans ),and the rapidly decomposing large-bodied, especially coprophagous,
