The margin of the bell is usually more or less lobed, eight of these lobes being especially distinct and carrying the sense-organs, the intervals between them being usually occupied by the secondary tentacles when these are present. The depressions of the subumbrellar surface are no longer deep funnels, but form rather shallow subgenital.

In many forms the margins of the mouth are prolonged into long fringed lobes, and in one family, the Hhizostomidce ( Stomolophus), the margins of these lobes may fuse to- gether, leaving, however, a large number of minute -openings along the line of fusion. These lead into canals traversing.
