Such studieswill probably reduce rather than increase the number of species of Fig. 202.—Bell-margin of Olindias malayensis, after Maas, inErgeb. Siboga Expedition, Monog. 10. Olindias singularis Browne. Olindias singularis, Browne, 1904, Fauna and Geog. Maldive and Laccadive Archipelagoes, vol. 2, p. 737, plate 56, fig. 2; plate57, fig. I.—Maas, 1905, Craspedoten Medusen der Siboga Expedition, Monog. 10 p. 48.—Bigelow, H. B., 1909, Comp. Zool. at Harvard College, 1. 37, p. 109, plates 4, 31, and 32. This species differs from others of the genus in that there is but a single lithocyst at thebase of each primary tentacle instead of a pair of lithocysts as in other species of Olindias. Bell hemispherical, 13 to 36 mm. wide. Gelatinous substance thick. There are 28 to 86primary tentacles. These all project from exumbrella side of margin, have oblong or shortspiral rings of nematocysts, and are stiff and not quite as long as the bell-radius. Their endsbear claw shaped adhesive pads. There are 4 to 12 secondary tentacles in each q
