Pentagomaster japonicut Sladen, Challenger Asteroidea, 1889, p. 272, pl. 46, figs. 1 and 2; pl. 49, figs. 1 and 2. Mediaster japonicut Verrill, Trans. Conn. Acad., vol. 10, 1899, p. 179. Diagnosis.--One of the largest if not the largest species in this or any closely allied genus. R = 102 mm.; r=65 mm.; R=1.56 r (varying to R = 1.36 r). General shape pentagonal or arcuate pentagonal, depressed, the edges of body more or less thickened; abactinal surface usually swollen on the radial areas; actinal surface nearly plane. Abactinal surface covered with fairly regular, spaced, hexagonal to quadrate tabula crowned with a convex group of numerous polygonal granules, the marginal series regular, sometimes compressed, and when dried showing a pit in the top. On the interradial areas tabula are quadrate and smaller. Many of the tabula with a bivalved pedicellaria, having thin, lamelliform jaws which are wider than high. These vary in size, equaling one-third or one-fourth the width of the tabulum. Marginal plates variable, covered with small flat crowded granules, forming an evenly rounded, or a decidedly tumid margin to ray; a bare space sometimes present on plates of both series, each superomarginal, with one to four small bivalved pedicellarise, whose thin jaws equal two to four granules in width. These are situated usually on the abactinal surface of the superomarginals near the margins; inferomarginals with usually only one pedicellaria or none. Actinal intermediate areas very extensive, the plates decreasing in size toward margin, and covered with crowded low flat polygonal granules, of which the marginal are slightly the largest; individual plates perfectly flat and variously...
