motive we packed an ample number of conventional collecting apparatuses /singling and sweeping nets,killing jars,sieves ,etc ./ with a second thought in the back of our minds that perhaps the Korean colleagues would help us operating any of these even for only a quarter or half an hour. We also took along with us more recent innovations functioning basically on self-operating principles: 16 funneled Berlese apparatuses, 3 Moczarsky-Szabó apparatuses /Pig.7/> 70 plastic cup-traps and one lialaise-trap. Besides all these care was taken on animal preservation too c Part of the material was stored in dry condition /rolls of blotting paper and phials/, others were put in alcohol as the preparation of the individual groups of animals required. Our main endeavour was to secure as many animals as possible. The biggest share, of course, fell to our special groups: Coleopt era /S. H0RXAT0YICH/ and Hymenoptera /J. PAPP/.Nevertheless, this did not mean that we had neglected the other groups.lt the end of this paper a list is given with the appropriate number of animals collected: insects are the first followed by annelids, crustaceans, millipeds, centipede,arachnids,molluscs and a few vertebrates . The 43 days at our disposal were spent as follows: 17 for collecting, 16 for cultural programmes, 6 were taken up by discussions and lectures while the rest /4 days/ was used for inland travels „ As it is readily seen a mere seventeen days fell as share to our primary aim/39 per cent of the available time/. Thus, for example, in the notable high mountaineous region of Pektusan we spent only 5 days against the 11 days planned /of this 5 days 3 poured with rain/. The longest period of time 10 days for collecting was Pyongyan and its environs, however,here DDT insecticides were profusely used rendering the collecting sites rather unfavourable. In many occasions have we trodded along paths and on litter of coniferous and deciduous forests where the ground was white from the extensive use of insecticides» Under such circumstances we had to do our 'utmost to secure as many animals as we could and the final number is
