Not illustrated. 1919 edition. Excerpt: ...irregular, with 5 or 6 slight indentations separating the margin into as many short lobes; or there may be no lobing but only 5 to 7 unequal facets. The lateral radial plates outside the area of intermediates are more regularly hexagonal. Superomarginal plates, 15 or 16 to the ray, the proximal 5 or 6 very-tumid and abactinal in position, the succeeding plates less tumid and with their transverse axis becoming more and more oblique to the abactinal plane. First plate slightly wider than long; succeeding 5 or 6 plates longer than wide; the remaining plates shortening and increasing in width so that the penultimate is wider than the plates of the midregion of ray, but not quite so wide as the first 2 plates. Granulation close and fine, similar to that of abactinal plate. Most of the plates have 1 or 2 pedicellariae similar to the abactinal. The first 4 or 5 plates have an irregular bare space in the middle, and in this there are irregular groups and lines of granules. Some of the outer plates show a similar bare space, but much smaller. Terminal plate rather obovoid, or ovoid, and narrowed at either end. Inferomarginals confined mostly to side wall of ray, closely granulate, and often with a pedicellaria. General surface slightly arched but not markedly tumid; first plate as wide as long; the next 7 longer than wide and the remainder wider than long. The fifth or sixth to fourteenth plates do not correspond in the 2 series but even alternate. The plates of the 2 series have nearly the same area; sometimes the superomarginals are a shade larger, sometimes the inferomarginals exceed, especially distally. Actinal intermediate areas very large, closely granulate, the granules convex and coarser than those of inferomarginal plates. Nearly all...
