Description. All examined bones are represented by small fragments, for which it is not possible to measure or describe them here. The remains do not appear to be those of Heterobranchus and are comparable in morphology with those that we interpreted as belonging to the genus Silurus . They are not, however, sufficiently recognizable to be assigned to any of the species.
