Rhizostomata triptera with clubs and filaments upon the mouth-arms. The 4 perradial canals arise directly from the stomach, but the 4 interradial canals result from the fusion of a number of anastomosing vessels which arise from the interradial sides of the stomach. There is no definite ring-canal, but merely a marginal network of vessels. There are no radial-muscles in the subumbrella, but the ring-muscles are well developed. Among the characters. FIG. 7.—Phyllorhiza luzoni from Varadero Bay, Luzon. Five arras are represented as if cut off close to the arm-disk. The muscular system is shown above, and the gastro-vascular canals below of minor importance, the subgenital ostia are wide openings, wider than the columns between them, and the sense-organs have a simple, exumbrella pit without radiating furrows. At the center of the arm-disk is a prominent, raised cluster of frilled mouths having filaments between them. Versura maasi Mayer.
