The eyes are perfectly lateral in the type and smaller specimens, but a little more dorsal in the 502 mm. fish. The posterior nostrils are nearer together than the anterior, the distance between them 32-36% of the length of Fig. 2 - Irvineia orientalis ; dorsal view of head of paratype of 144 mm. The teeth are small, more comparable in size with those of Eu- tropius niloticus than with the larger teeth of E. depressirostris, with points directed backwards. T
