Somssich-hegy (secondary, water-deposited loess?) we cannot speak of a cold faunal picture in the series of layers 2 to 27 (all homogenously yellow). The lower layers with more brownish colour prove rather a yet warmer climate in general (layers 28 -30). The whole faunal picture of the profils is the same, the differences are quantitative but not qualitative ones. The difference between the lower and upper levels of different colour seems to be in the vertebrate fauna; according to the verbal communication by Gy. TOPÀL the horse shoe bats are present only in layer 25, which are absolutely missing in the upper levels and are replaced there by the insectivorous bats (Vespertilionidae). This observation agrees with the abovementioned findings of KROLOPP, according to which in levels 22-24 the snails which require warmer conditions are more frequent (snails are unfortunately missing below layer 241). The sporadic remain of the Barbary ape in this level confirms the "Mediterranean" character of a lot of other elements. In my opinion we can interpret the picture reflected by the faunal context of the series as follows: it expresses the effect of a glacial wave in the north and at the beginning of this wave some northern elements of those times, - among them the lemmings, migrated to the south, some of them reached the Mediterranean viz. sub-Mediterranean. In any case, there is a fauna with lemming remains from France at Montoussé 5, - geologically considerably older than Somssich-hegy 2., - and more to the south (cca. 43° Northern Latitude). An interpretation of the lemming remains at the northern foot of the Pyrenees as having been taken by birds of prey from the high montains to the locality is improbable (CHALINE & al. 1976; the locality Montoussé lies at about 700 m above see level and in its neighbourhood there are mountains of 1000-2000 m altitude). The hypothesis outlined above seems to be more likely, especially because we lack any indication in the Villány-Hills of the presence of any higher mountains during the whole Pleistocene at all.
