The name given to the individuals of a family of ganoid fishes, remarkable for the structure of the dorsal fin, which, instead of being continuous, is separated into twelve or sixteen strong spines, distributed at short intervals along nearly the whole of the back, and each bordered behind by a small soft fin. Two species of this curious group are living, one of which inhabits the Nile, and the other the Senegal; but the family attained its maximum in palaeozoic times, most of the old red and carboniferous fishes belonging to it.
