Statistics: Descriptive statistics were calculated for each species (table 1). The geographical- ly scattered samples of D. nitedula were pooled due to the very few numbers of specimens from each locality (often one specimen per locality). In addition, many crania were either broken or of juveniles, and could not yield complete measurement sets. I could not divide the specimens in such a way that reasonable geographic samples would yield enough complete or complimentary measurement sets to estimate means. Large series of the forest dormouse are uncommon, although Rossolimo (1971) did have access to large samples from several of the independent republics of the former U. S. S. All samples of D. laniger were pooled due to small sample sizes, but because the species has a very limited geographic range the pooled samples may well represent one population. The three specimens of the new species are from two nearby localities and are considered to exemplify one population. Differences between two sample means were tested by t-tests, and were considered signifi- cant at the a = level or lower. Ratio diagram: Proportional craniometric relationships among species are illustrated by a ratio diagram (fig. 9). For each measurement, the absolute value of the mean and plus and minus two standard errors of the mean were converted to logarithms. For each dimension, the logarithm of the mean of the standard (Dryomys nitedula) was subtracted from the logarithm of the mean of D. laniger and the new species, and the logarithms of plus
