Ambulacral plates only 9, the uppermost and sometimes the two uppermost without primary tubercles; ambulacra about 4'5 mm. wide in midzone; poriferous areas very narrow, the pore-pairs in almost vertical arcs of three near the outer margin of plate. Primary tubercles relatively large, without crenulation, but conspicuously perforate. Abactinal system 8-5 mm. across; oculars moderately large, pentagonal, with pore distal to center, and several small tubercles; all decidedly exsert; genitals large, wider than high, heptagonal, well covered, except along lateral and distal margins, with secondary and miliary tubercles; genital pore small, situated about half way between center of plate and the distal tip; with the latter it is connected by a shallow furrow; anal system 4'25 mm. across, covered by numerous, small, thin,. Fig. 4. Abactinal view of portion of test of Coenopedina capensis sp. nov. X 5. somewhat overlapping plates, a dozen or more of which carry secon- dary tubercles and spines, Peristome 7-5 mm. across, covered by the five pairs of large buccal plates and numerous thin peristomal plates; a few of the largest of the latter carry pedicellariae while the buccal plates in addition to numerous small tridentate and ophi- cephalous pedicellariae, carry a very few secondary spines; gill cuts so shallow as to be barely perceptible. Primary spines all broken, so it is impossible to state their length definitely, but the largest were -75--80 mm. in diameter at base and were thus probably 15-20 mm. long; they are not at all hollow and the surface is covered with 25-30 very delicate, parallel, longitudinal ridges, which are microscopically serrate; secondary spines similar but conspicuously Please note that these images are extracted from scanned page images that may have been digita
