Side arm plates moderate, in contact both above and below; each plate carries six or seven straight, smooth spines, of which the next to the uppermost is longest and may exceed three joints; rows of spines not approximate dorsally. Tentacle scale single, very large, flat, rounded, and more or less distinctly curved outward around the base of the lowest arm spine
