 \- Lukuga Tanzania -6. Taxonomic Remarks. Synodontis dhonti
 Democr tic Republic Boulenger is known from a single specimen, collected in
 of Congo 1912. Synodontis irsacae Matthes was placed into the
 T synonymy of S. dhonti by Matthes (1962). Morpho-
 logical differences between these species were said to
 be due to ontogeny, but we have found no specimens
 that support this claim. We consider S. dhonti and S.
-8- L- b`- 8- irsacae to be distinct species. Evidence for this conclu-
 Warinpa sion is presented in the description of S. irsacae.
