Abstract

The results of a detailed biometrical and statistic morphological study is given on the Early Pleistocene Cricetus praeglacialis material of Villány 8 and a recent Hungarian Cricetus cricetus population with the revised investigation of the Cricetus praeglacialis type-material. The most important conclusions are the next: – the hamster of Villány 8 is identical with the C. praeglacialis typematerial; – the differences between the fossil and the recent material are briefly the following: the measurements of C. praeglacialis are larger, the ranges of these measurements are broader, the morphological variability is broader as well; – these differences establish the presence of two different species and not two subspecies like in the original description of SCHAUB, 1930; – the evolutionary connection between the fossil and the recent species is probable, but the C. praeglacialis – C. cricetus line is only one of the four presumed philetic lines of the Hungarian Pleistocene hamsters.
