Discovery reports (1940) Discovery reports discoveryreports18inst Year: 1940 l62 DISCOVERY REPORTS lower brachials are shown in Fig. 9 b. The long second brachials incise the first and form slight shoulders with them. Syzygies occur between brachials 3 + 4, 9 + 10 or exceptionally 8+9, 13 + 14 or 14 + 15, and thereafter at intervals of two to four, usually three, muscular articulations. Fig. 9. Kcmpometra grisea. rt, cirrus. 6, proximal parts of two rays, c, forty-third to forty-seventh brachials. d, P3 from the under side showing the ovary containing large eggs and the brood-pouch containing a penta- crinoid larva, e, side-plates and spicules of distal pinnules, a-b, X13. c-d, x 15. e, x 80. The two brachials following the first syzygial pair are rectangular, about twice as broad as long. Those for some distance beyond are somewhat wedge-shaped and about as long as broad. The distal brachials are elongated and slender, rectangular, with the articulations, muscular and syzygial, slightly swollen (Fig. 9 c). The distal edges of the brachials are everted and produced into frills of tooth-like spines; their entire surfaces, as well as those of the ossicles of the division series, are very finely thorny.
