Treatment

A large specimen ( Fig. 2P View Fig ) in our material is somewhat higher in its overall shape and the antero-dorsal angle is more pronounced than those of the similar-sized Chattian type specimens from the Aquitaine Basin, southwest France ( Nolf & Brzobohatý 1994: pl. 2, figs 5, 11); the smaller specimens in our material ( Fig. 2 View Fig N–O) are characterised by thick otoliths and a convex outer face, and are reasonably similar to the type series from Aquitaine ( Nolf & Brzobohatý 1994: pl. 2, figs 6–10). Because modern alepocephalid otoliths commonly show a great intraspecific variability (e.g., Nolf & Brzobohatý 1994: pl. 2, figs 1–4), the specimens in question are all assigned to X. senesi . The studied material, including large and small specimens, allows us to refer the otoliths figured by Lin et al. (2015: fig. 2(5), as Xenodermichthys aff. copei (Gill, 1884)) to juvenile specimens of X. senesi .
