I believe that the specimens so named should be reunited with Schilbe mystus.

This is a species clearly distinct from Ch. macrops, having the adipose fin much shorter and further distant from the dorsal fin. In this respect it agrees with Ch. nigrodigitatus, which, as a rule, has a more contracted snout and narrower mouth. However, I have examined large specimens which it is difficult to refer to either of these two species with certainty. And the difficulty is increased, as I find that there are specimens with eleven and with thirteen anal rays in both the narrow-snouted form (Ch. wigrodigitatus) and the broad-snouted (Ch. Büttikoferi). Possibly more than these two species should be distinguished. Miss Kingsley; found Ch. Büttikoferi at Kondo-Kondo and in Corisco Island.
