Centrocidaris doederleini (pedicellariae)
Description From left to right: a. Head of a globiferous pedicellaria with a single valve. The stem is provided with a limb. b. Part of transverse section of aboral primary spine: The furrows between the ridges are filied with cortical meshwork (anastomosing hair) covered by a glabrous crust which is perforated by minute pores. This crust gives the spine a smooth appearance. The ridges are perceptible only by the colour, because they are rather translucent. The ambital primary spines become gradually more thorny. c. Apical system. d. Secondary spine.
