STARFISHES OF THE PHILIPPINE SEAS. 317 



blunt spine (sometimes 2) and a broadly spatulate entrenched pedi- 

 cellaria ; adambiilacral plates with a palmate furrow series of 5 to 7 

 unequal, rather slender, more or less compressed spines, and distally 

 1, proximall}' 2, heavy subambulacral spines, resembling those of the 

 actinal intermediate plates. DiflPering from C. childreni in having 

 much heavier marginal and actinal spines and numerous pedicel- 

 lariae; from C. pedicellarh in having heavy actinal intermediate 

 spines, more numerous and longer furrow spines, and prominent 

 spines in the center of disk; from C. haccatus in having longer 

 spines generally, numerous pedicellariae, more numerous furrow 

 spines, and a few prominent abactinal spines, instead of tubercles 

 all over the abactinal area. 



Description. — Abactinal plates subcircular, the median radial the 

 largest and convex, the others slightly convex, and all surrounded by 

 a peripheral series of depressed subtruncate, foliaeous granules flush 

 with the surface and overlying the rather conspicuous intervals be- 

 tween the plates. The apical area, enclosed by the primary radials 

 and basals, contains smaller plates of two sizes in two circles sur- 

 rounding the larger very convex central plate, which, like the slightly 

 larger, but similarly convex primary radials, bears an upright rigid, 

 robust, blunt tubercular spine 3.5 to 5mm. long, and at the base 

 as thick as about half the width of plate. The following one or two 

 plates, or the second following plate, bears a shorter but similar 

 spine, while the remainder, with the exception of the last 5 or 6, 

 have a central tubercular granule, decreasing in size distad. The 

 radial plates inside the apical area, the primary basals, and a few 

 neighboring plates of the disk also have a central tubercle. A num- 

 ber of plates on the disk and proximal portion of rays — about 35 

 in all — bear a pedicularia with two very broadly spatulate, entire, 

 jaws which fit into well-marked depressions, when open. On some 

 plates, when open, the jaws reach nearly across. Papulae large, the 

 area including all the disk except a very narrow interradial portion, 

 extending on the margin only to middle of the first plate, and the 

 last six or seven abactinal plates. There are six around each plate. 

 The abactinal area of the ray is narrow. From the third supero- 

 marginal to the seventh there are only three longitudinal series of 

 plates separating the marginals, and beyond the seventh only one, 

 the width of the area here being less than that of the marginals. 



Superomarginal plates, 13, very tumid, and decreasing regularly 

 in size, the first with tAvo rigid tubercular spines in a transverse 

 series, the others with one spine on the margins of the ray. The 

 lateral face of the plate is about as wide as the dorsal. The spine is 

 borne on the summit of a subtubercular tumidity and in height equals 

 the distance between its base and the inner margin of plate. It is 

 smooth, blunt, subcylindrical, very slightly tapering and constricted
