. CpoCsom) Cz' Text-fig. 38. Nectopyramis natans, polygastric stage. A, foreshortened view from lower end to show longitudinal ridges; B, dorso-lateral view, x 7. The eudoxid was described and figured by Bigelow (191 lb, 1913), and has been taken several times since. Curiously enough the polygastric stage has much the same long-bow shape as the eudoxid. The 'Discovery' polygastric specimen is 2 cm. in length, shaped like a long-bow, pointed above at one end, and truncate at the other. The hydroecium runs practically the whole length. At mid-length it contains the large gastrozooid and tentacle

At mid-length it contains the large gastrozooid and tentacle, and what are probably the buds of a second and third. On the dorsal surface are three longitudinal ridges extending from the apex to the nectosac, which lies about a quarter of the total length above the posterior truncate end. There is also a pair of lateral ridges running from the apex, past the nectosac to the truncated end. There is a single longitudinal
