Only one small species, Ch. multibarbis, is known, from the coasts of India and China.

To complete the list of Scorpænoid genera, we have to mention Tænianotus, Centropogon, Pentaroge, Tetraroge, Prosopodasys, Aploactis, Trichopleura, Hemitripterus, Minous and Pelor.
Eighth Family—Nandidæ.
Body oblong, compressed, covered with scales. Lateral line interrupted. Dorsal fin formed by a spinous and soft portion, the number of spines and rays being nearly equal; anal fin with three spines, and with the soft portion similar to the soft dorsal. Ventral fins thoracic, with one spine, and five or four rays. Dentition more or less complete, but feeble.
This small family consists of two very distinct groups.
A. Plesiopina. Marine fishes of small size, with pseudobranchiæ and only four ventral rays. Plesiops from the coral-reefs of the Indo-Pacific, and Trachinops from the coast of New South Wales, belong to this group.
B. Nandina. Freshwater fishes of small size from the East Indies, without pseudobranchiæ, and five ventral rays. The genera are Badis, Nandus, and Catopra.
