The longitudinal pennons ofthe'Edwardsia-mesenteries' are strong, in the reproductive region with 25 to 30 folds which z' '\Jif \\\M ' '''JSi / are high in the outer part of the pennons and here rather richly branched, while the inner part is lower and only Uttle ramificated (textfig. 63). The outer lamellar part of the mesenteries issues at Textfigs. 63—64. Edwardsia vegae. Transverse section of pennon (fig. 03) and of parietal muscle (fig. 64). a good distance from the outside Fig. 63. of the pennon. The parietal musc- les are rather strong, with some- what numerous folds which are long in the outer part, in the inner one short. The former are placed almost perpendicularly to the lamella of the mesenteries; the latter are turned inwards (textfig. 64). Whether the parietal muscles are continued on the column I cannot decide as they were not well preserved in their outer part. The species is dioecious; the specimen was a female. Edwardsia fintnarchica n. sp. PI. I, figs. 10, 12. Diagnosis: Physa well-developed, perforated by apertures. Scapus-periderm thin. Nemathybomes very small, but numerous, scattered over the whole surface of the scapus, not discernable to the naked eye. Nematocysts of the nemathybomes (26) 36—48 (62) X 3— (4) fi, those of the capitulum 10—12 fi, those of the tentacles 22—26 X —3 /i, those of the actinopharynx 30—35 x —3 /n.
