FIGURE 4. Comparison of the right lateral wall of the braincase in species of Bitis. Each figure part shows the braincase in approximately lateral (some more dorso- or ventro-, and some more postero or anterolateral) view. A) B. arietans (BMNH 1964.1249), B) B. nasicornis (BMNH unnumbered), C) B. gabonica (BMNH unnumbered), D) B. harenna sp. nov. (ZMUC R68255), E) B. parviocula (ZMUC R68254). F) B. parviocula (ZFMK 63067). Parts A–C are photographs of osteological preparations; parts D, E and F are µCT volume reconstructions. Scale bars 5 mm. Abbreviations: bo = basioccipital, eo = exoccipital-opisthotic, f = fenestra ovalis, p = prootic, pa = parietal, s = proximal end of stapes. * = prootic ridge present in B. parviocula but not in B. harenna sp. nov.
