Éhik, Gy.: The glacial-theories in the light of biological investigation

Dr. .J. ÉHIK are occupied by new forws, constituting the steppe fauna. This latter fauna is a conglomerate partly consisting of thermophil elements (with a southern origin) and partly of some arctic forms left behind, as well as of some eastern species. 5. The formation of forest-zones in the North of Europe, charac­terized by special faunistical elements, belongs also to that period. The migration of the fauna and flora, taking place from North to South, might be so easily controled that I do .not find any reason for enumerating at this place special proofs with respect to this biogeo­graphic phenomenon, and so I think that the maps here added will be rather true, at least in bold outline. Still the question arises, how far 1 succeeded to represent accurately the motion of the ice? An answer with respect to this shall be given hereafter. At present I should like to give an oversight of the different faunae. Future investigations will probably ascertain that the thermophil fauna — recorded by Dr. KORMOS as preglacial. 1 — existed as early as the lower Pleistocene strata of Germany, as marked on my map and proved, up to now, by the fossil faunae of Mauer and Mosbach. 2 The more southwards we go, the more frequent is the occurrence of such faunae, and we will find some spots, where this thermophil fauna per­sists through the whole Quaternary. Such a territory is represented for instance by the southern parts of Hungary, offering a rich material of this kind. 3 A solution of the problem regarding the chronological suc­cession of these faunae was attempted by Prof. Dr. MÉHELY in his clas­sical work on the Fibrinae of Hungary. He was the first to remark the existence of chronological differences occurring between the various thermophil faunae. I have no intention to go into further details concer­ning the quoted publication, but I should like to direct the attention to 1 T.
