I do not believe in any general vertical spawning migration among deep-sea pelagic animals, even if the eggs develop in the upper strata of the ocean ; the eggs themselves must rise to the surface. If this were not so, we Fig. 528. Cyclothone microdon, Giinth. Nat. size, cm. should undoubtedly have taken, in the upper layers, many more of the pelagic fishes peculiar to deep water, whereas we took them with ripe eggs in deep water. The eggs captured and examined by us vary greatly in size and size of fish appearance; Fig. 530 shows the relative size of some of them. A is a small egg a little more than mm. in eggs
