Comparing morphology and cranial osteology in two divergent clades of dice snakes from continental Europe (Squamata: Natricidae: Natrix tessellata)

Figure 6.

The comparison of selected skull bones between the ‘Europe’ (DJ4916; A, C, E, G, I) and ‘Greece’ (DJ5813; B, D, F, H, J) clades of Natrix tessellata: frontal (A, B), parietal (C, D), supraoccipital (E, F), parabasisphenoid (G, H) and basioccipital (I, J) bones from dorsal (left column) and ventral (right column) views. For abbreviations, see Material and Methods. The scale bar indicates 1 mm.
