. Echinoderma of the Indian Museum ... Collected by the Royal Indian Marine Survey ship Investigator. ... Echinodermata. 100 ECHINODIORMA OF THK INDIAN MuSEUM, PART VII. Cirri XVIII, 17-18, 20 mm. long; first segment twice as broad as long, second nearly or quite as long as broad, third to fifth twice as long as the proximal dia- meter, sixth slightly shorter, a more or less marked transition segment; following segments gradually decreasing in length , the terminal segments being only slightly longer than broad : penultimate segment about as long as broad; the third to the sixth segments are very strongly " dice-box " shaped, with the distal edge all around produced, except on the dorsal side ; from the seventh onward both these features become less marked, and the cirrus becomes somewhat compressed. Fig. 4.—Eudiocrinus ornatus. Lateral view of a typical specimeu laterally; there are no dorsal spines; opposing spine sharp, prominent, arising from the entire dorsal surface of the penultimate segment, equal to about one half of the lateral diameter of that segment in height : terminal claw equal in length to the penultimate segment, stout and strongly curved. Disk with a few rather large plates along the ambulacra, and well plated in the anal area. Ends of the basal rays visible as small tubercles in the angles of the calyx ; radials projecting slightly beyond the centrodorsal, slightly concave distally ; IBr^ and IBr.^ united by pseudosyzygy, forming an oblong pseudosyzygial pair.
