Family 9. Sisoridae. Differ from the Bagridse in certain features of specializa- tion, such as the absence of pterygoid and post-temporal, the contraction of the head of the hyomandibular, which articu- lates with the sphenotic only, and the division of the air- bladder into two lateral sacs. Lower surface of head and abdomen flat and paired fins horizontal. Nostrils close together, with a more or less developed barbel between them. Gill-membranes free {Nangra, Bagarius) or attached to isthmus. Vertebrae34 to 40 (15-19 + 19-23) ; parapophysis of the fourth vertebra a lamina which is decurved anteriorly, forming a semicylinder; parapophysis of the fifth vertebra very strong, extending outwards to the skin, rarely uniting with that of the fourth to form a complete cylinder.
