The auricles are now forming, and the tentacular ridge has appeared as a slight fold or line as shown, but it is not connected to the tentacular bulb, and possesses no tentacles.

(Tentacle omitted, being same as in Fig. 7.) 2. Juncture of paragastric and auricular canals. 3. Mouth. It is now easy to see how the adult structures are completed. As the junction of the paragastric and auricular canals moves up- ward forming the auricular groove, the tentacular ridge and labial ridge grow with it. The large branched tentacle disappears, and small tentacles appear along the tentacular Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
