1. Pyongyang and its wider neighbourhood (a diameter of about 100 km) Disregarding the inhabited sections, the region may be divided into two sharply delimited areas: a/ an agricultural territory (valleys and plains), and b/ an area with the natural plant cover (mountainous districts). The agricultural area is characterized by its complete utilization for this purpose. Rice (paddyfields ) is quantitatively the most extensive culture ,while the ratio of fields (dry tillage), orchards and vegetable gardens is considerably smaller. These latter generally occupy the milder slopes of the mountains. Their fauna is now essentially altered or destroyed by the application of total chemical control: the overwhelming majority of the species had perished and only a meagre representation remains, and that merely sporadically, too. In the areas drawn under culture, and chiefly owing to the paddyfields, all natural waters, including the smallest brooks, have been regulated: water is distributed by orderly canals in perfect condition. In accordance with their purpose, they contain water only temporarily, thus precluding the survival of the original flora and fauna even in these sites.The number of streams still in their original beds is extremely small and their water content meagre. Still, in this region it is these natural waters and their banks which represent the last refuge of the original fauna and which gave some possibility for small-sized collectings (Nos. 11-15). One might relegate here a characteristic habitat of the environment of Pyongyang, the extraordinarily meandering Te-Dong River, uncontrolled in many places. The river bed, carrying the profuse summertime monsoon rainfalls, is locally many hundreds of meters wide; on the occasion of our visit, its waters were shallow, with the extensive bed and a part of the bottom remaining dry. The section of its shores we have travelled was partly stony partly sandy, suitable for zoological collecting. The composition and amount of the fauna is,
