The 8 "Edwardsia-mesenteries" have well-developed, longitudinal pennons. The folds are rather high, but not as branched as in E. pallida (textfigs. 30, 31). The most ramificated folds are situated in the outer part, but also in the innermost part there are one or two such folds. The middle part of the pennon is more weak. The number of the folds is about the same as in E. pallida. The outer lamellar part of the mesenteries is attached to the pennon at some distance from its outside, in the repro- duced pennon (fig. 30) a Uttle nearer to the centre. The parietal muscles are com- paratively weak, and more or less dichotomously branched \ (textfig. 32), they are, how- ever, sometimes a httle stronger than the reprodu-.
