STARFISHES OF THE PHILIPPINE SEAS. 251 



ules, those of the peripheral series being " trimmed " to a straight 

 edge on the plates adjacent to the hiterahnost radial series. The 

 radial papular areas are oblong rather than lanceolate; papulae on 

 center of disk. There are a very few slender entrenched pedicel- 

 lariae, with a fairly wide base tapering into very slender jaws, on 

 the abactinal plates, and similar ones on the dorsal and lateral sur- 

 faces of a few of the proximal superomarginals. They have no defi- 

 nite position on the plate. 



The plates of the papular areas when examined from the inner or 

 coelomic side are hexagonal with arcuate sides. The radial and 

 either adradial series are joined together by internal oblong or 

 elliptical ossicles at the corners of the plates, and each adradial series 

 is also joined to the second longitu.dinal series in the same way. 

 There are, consequently, 4 longitudinal series of the internal ossicles 

 extending transversely between the plates and 3 series of longitudi- 

 nally directed ossicles between these. As the papular area increases 

 in size new ossicles appear, so that in the cotype there are 6 instead 

 of 4 longitudinal series of transversely directed ossicles ; these do not 

 encroach on center of disk except in fully grown examples. 



Superomarginals forming a slightly to decidedly raised border 

 to abactinal area. They are blocklike and the angle between the 

 dorsal and lateral faces is abrupt, swollen, and less than a right 

 angle, there being a depression all along lateral face of disk and ray. 

 Superomarginals increasing in size up to the fifth. Either this or the 

 sixth meets its fellow medially ; dorsal surface of first 4 plates slightly 

 wider than long; fifth decidedly wider than long; thence the width 

 decreases more rapidly than the length, the ninth being square and 

 the succeeding plates slightly, then obviously, longer than wide. 

 Height of plate interradially and on proximal part of ray slightly 

 more than half the width of dorsal surface ; near the end the 2 dimen- 

 sions are nearly equal. Granules small, depressed, circular, close 

 but not touching, similar to those on the abactinal interradial plates. 

 Number of plates in cotype, 21 or 22. Terminal plate ovoid, pointed 

 proximally. 



Inferomarginals about as wide interbrachially as superomarginals, 

 but decreasing regularly in width from the first plate, the fifth being 

 about as wide as long, and the succeeding longer than wide, as 

 seen from below. Ten inferomarginals, beginning with the eighth, 

 correspond to 20 adambulacrals (19-21). Granulation similar to 

 that of superomarginals. Many of the plates have 1 or 2 slender 

 entrenched pedicellariae on the actinal surface. 



Actinal intermediate plates in 5 chevrons, the outer reaching 

 eighth inferomarginal. The plates are plane and covered with 

 slightly spaced, convex, polygonal, or hemispherical, equal granules, 

 the sutures between the plates being narrow but conspicuous. Many
