This extensive family is divided by Dr. Günther into eight sub-families and seventeen groups, the distribution of which is as follows:— Sub-family 1 (SILURIDAE HOMALOPTERAF) is confined to the Old World. It consists of three groups: Clarina (2 genera, Clarias and Heterobranchus) ranges over the whole area of the Ethiopian and Oriental regions, to which it appears to be strictly confined; Plotosina (3 genera, Plotosus, Copidoglanis, and Cnidoglanis) ranges from the eastern coasts of Africa to Japan, Polynesia, and Australia, in seas and rivers; Chacina (1 genus, Chaca) ranges from India to Borneo.
