In these rudiments of stolon the sclerites are of the same tyjie as in the zooid body. The zooids are thin-walled in their whole length, ami thus it is not possible to distinguish clearly between an and an anthocodia; and if the upper part in one of the fifty spec- imens had not been retracted the species should probably errone- ously have been described as non-retractile. The of the only retracted specimen shows (fig. 5 h) that, by retraction, the upper part of the zooid with the crown of sclerites is simjily withdrawn into the coelenteric eavitv. whereas the u])]ier part of that jiortion of the zooid body which is arnu'd with sally arranged sclerites (i. e. the lower part of the anthocodia) about and above it. The tentacles are not invertecl wluni retracted, but simjily |iut down into the ((lelentcric cavity. IJiscussion: See under the following s^iecies. Distribution: Davis Strait, â 2"2.''iS m.
