To its middle and distal half are attached the successively developed gonophores. This peduncle is the homologue of the central organ described above, and represents the remains of the part of the stem to which the gastrozooid was originally attached, or perhaps the peduncle of the gastrozooid. Nectopyramis natans (Bigelow), 191 lb, = Archisoma natans Bigelow, 19116. An eudoxid of this interesting Prayid was taken by 'Discovery II'between 1650 to 950 m. at St. 1586, off Italian Somaliland. The polygastric stage has never been recorded. I take this opportunity, therefore, to mention two polygastric specimens, one taken by 'Discovery' at Station ioi, off South- west Africa, in a closing net at a depth between 2480 and 2580 m.; and the other by 'Rosaura' in 1937, at a depth between 750 m. and the surface, between St Paul and the Brazilian coast.
