Dorsal view of the head and trunk of: (a) Sefcosfoc/es goodei and (b) Oligocoftus snyderi. Note the difference in outlines of the heads. The optic lobes are large in Sehastodes (Fig. 2), giving the head a high profile when viewed in lateral aspect. About 25 to 27 myomeres may be seen in each of these four species. This agrees closely with the numbers of vertebrae (26 or 27) found by Clothier (1950) among adults of 10 species

The optic lobes are large in Sehastodes (Fig. 2), giving the head a high profile when viewed in lateral aspect. About 25 to 27 myomeres may be seen in each of these four species. This agrees closely with the numbers of vertebrae (26 or 27) found by Clothier (1950) among adults of 10 species of Sehastodes that he examined. The dorsal finf old has a small discoidal indentation on each side, above, the approximate center of the trunk (Fig. 2). A fine line extends from each member of this pair of indentations to a nearby myocomma. These structures were found in all of the four species. I have not observed them in larvae of other genera, nor do I have any knowledge of their function. MELANOPHORES The distribution of melanophores in the newly-hatched larvae are shown in Figure 2. Table 1 brings out similarities and contrasts in the distribution of melanophores among the four species. During the yolk-sac stage the pectoral fins of S. goodei become en- tirely black and those of S. paucispinis develop black margins. The pec- toral fins of the other two species remain unpigmented during this period. A few melanophores are added to the region over the head in S. goodei and a few appear in this region in S. paucispinis during the yolk- sac stage. During this period the top of the head remains unpigmented in the other two 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 California.
