. Ctenophores of the Atlantic coast of North America. Ctenophora -- Atlantic Coast; Ctenophora. CTENOPHORES OF THE ATLANTIC COAST OF NORTH AMERICA is in the plane of the pole-plate, while its narrow axis is in the plane of the tentacles when these are present. This buccal chamber is commonly called the "stomach," but its walls are of ectoderm and bear cilia, which are especiall}' well developed in the Beroidae, where they occur in linear, longitudinal areas extending from the lips inward. This chamber is certainly a food receptacle, and we will call it the stomodaeum. The stomodaeum leads into the entodermal part of the gastric cav- ity, a laterally compressed chamber called the funnel or infundibulum. The wide axis of the fimnel is perpendicular to that of the stomodaeum and it lies in the plane of the two tentacles to the basal-bulb of each of which it sends a canal. It also sends a canal upward to the sense-organ, and this axial vessel, which is called the funnel-tube, opens by a pair of excretory pores on two diagonally opposite sides of the pole-plate. In the Beroidae there are two lateral funnel-tubes, one to each excretory pore. J P ex ex- -|).
