Longitudinal pennons of the mesenteries in the reproductive region with about 25â30 strong folds which are rather high and richly ramificated in the outer part, low and only sUghtly branched in the inner one. Outer lamellar part of the mesenteries attached to the pennon at some distance from its outside. Parietal muscles with somewhat numerous, in the outer part closely packed folds; in transverse-sections through the re- Textfig. 62. Edwardsia vegae.

Expansion of the parietal muscles on the column? Colour in presen-ed state: Scapus dirty-brown. Dimensions in strongly contracted state with the physa and one part of the sca- pus involved: Length cm, largest breadth about cm. Occurrence: Arctic Sea of Siberia. Off Pittlekaj North of the winter harbour of the Vega 9â10 fms. stones (Vega-Exp. 1879, No. 1002) I sp. Exterior aspect: The phj'sa is well- developed, but involved. It is perforated by a central aperture, surrounded by a ring of pro- bably 8 apertures. The scapus is provided with 8 distinct, longitudinal furrows and is thus polygonal. The nemathybomes are large, especially in the lower part, scattered over the whole surface and distinctly discernible to the naked eye. The capitulum being damaged, I cannot decide whether it is polygonal. The short tentacles are 16 in numbe
