pering tentacles, longer than the bell-diameter. Notmore than 2 to 5 sensory-clubs per lappet. Clubs similar to those of S. albescens. TropicalPacific and Atlantic Gulf Stream. Distinguished from S. marshalli by its soft, gelatinoussubstance, fewer sense-clubs, and greater number of tentacles. It is possibly identical withS. faberi and S. bleeki of Haeckel. Solmissus faberi Haeckel. Solmissus jaberi, Haeckel, 1879, Syst. der Medusen, p. 350. Bell lenticular, biconvex, 20 mm. wide and 7 mm. high. 24 tentacles hardly as long asbell-radius. 72 sensory-clubs without otoporpae. 3 on each bell-lappet; the 24 lappets form a 38 484 MEDUS/E OF THE WORLD. collar around the bell; they are rectangular, somewhat wider than long, and hardly one-fourthas long as bell-height. 24 radially situated, heart-shaped stomach-pouches have their wideends outward, somewhat wider than long, and contain the gonads.
