Figure 19. Photographs of neurocrania in anterolateral view showing aspects of the trigeminofacialis chamber in four osteoglossomorphs. A, Hiodon alosoides (UMA F10581, 315 mm SL). B, Chitala chitala (UMA F10349, 437 mm SL). C, Pantodon buchholzi (UMA F11265, approx. 50 mm SL). D, Gnathonemus petersii (UMA F11267, approx. 140 mm SL). Arrows indicate position of the foramen for the nerve historically called the combined cranial nerves V and VII; this nerve likely contains a portion of the anteroventral lateral line nerve as well. In Gnathonemus, as in some other mormyroids, there are two separate foramina (i.e. one for V and one for VII).
