Juvenile of Mel'ibe leonina at months after metamorphosis showing the foot (f), double row of lobate cerata (C) containing dendritic branches of the digestive diverticula, and oral hood (OH) surrounding the mouth. The oral hood bears peripheral hood tentacles (HT) and a pair of rhi- nophores (R) mounted on a rhinophoral process (RP). The arrowhead indicates the position of the anus. FIGURE 2.

Larva of M. leonina immediately after hatching showing the velum (VE), foot (F), and statocyst (S) of the cephalopedal mass and the stomach (ST), right and left digestive diverticula (RD and LD, respectively), intestine (I), larval kidney complex (LK), mantle fold (MF), and shell (SH) of the visceropallial mass. The arrowheads indicate the tuft of long, stiff cilia at the apex of the foot. FIGURE 3. Late stage larva of M. leonina showing the right eye (EY), propodium (P), enlarged stomach (ST), left digestive diverticulum (LD), and the shell (SH), statocyst (S), and velum (VE). The arrowheads indicate the rudiments of the primary cerata. At the aperture of the shell, the associated perivisceral epithelium is termed the mantle fold and its cells are specialized for secretion of shell material (Fig. 7). The emainder of the mantle extends from the aperture of the shell to the cephalopedal mass and thus demarcates a shallow mantle cavity in the newly hatched 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. ).
