Zool. Jahrb. Syst. 57: 497-536, 14 f., t. 4.
Abstract / Notes
The material obtained from various ponds, lakes and streams is chiefly new. There are detailed descriptions of Bothromesostoma primitivum, Planaria grubiiformis, Sorocelis relicta. S. eudendrocoeloides, S. elongata, Bdellocephala mediobuccalis, and B. kamtschatica. There are concluding zoogeographical remarks, particularly concerning Sorocelis, a genus widely spread throughout waters of an alpine character in that part of Asia most closely related to the former Angaro-Chinese continent. Close relations between some of the Kamchatka forms and species in Lake Baikal indicate a common origin of the fauna of the two localities. The species of Planaria and Bdellocephala found in Kamchatka are all limacolous types and have their nearest relatives in Lake Baikal forms; they occur in relict waters of postglacial origin. Sorocelis probably invaded Kamchatka during the Tertiary and withstood a period of strong glaciationin alpine lakes and streams.
