The cephalic cuirass is incomplete ; thespinous portion of the dorsal is armed with strong spines, often providedwith poison glands, but is not separate. The anal generally has threespines. The cranial bones are usually very spiny, often distorted, andfleshy processes may be developed on the head. The myodome is base of the pectoral fin is broad and vertical, and one or two lowerdermal rays may be separate. The radials are constricted. The scalesmay be lost, and the gills reduced to three and a half, one slit being 29. Fig. 466. Sebastes percoides, Sol. (After Giintber.)
