A gruup of dorsal plates and papular pores from middle of the base of a ray, seen from the inside, much enlarged. The dorsal surface is covered with rather large, round, mostly equal, convex, stellate paxillae, each covered with a large number of regularly divergent, small, nearly equal, obtuse, rough spinules, of which the larger have from twenty to thirty. Those at the margins form simple, deep fascicles. When the spinules are removed, the plates are in the form of low, round-topped or nearly hemispherical bosses, mostly nearly equal in size and form, with only a few smaller ones, here and there, and separated by intervals of flexible integu- ment, with about six papulae standing singly and regularly around each plate. The papulae are lacking on a small central area of the.
