All the plates of the dorsal side of the disk, excepting the radial shields, rise into a low knob surrounded by concentric rings. The radial shields are on the contrary smooth, and even usually somewhat sunken in the middle; they are oval, about half the length of the disk radius, separated by a column of plates, the innermost one of which is generally the most conspicuo
