Total length FIGURE 9. Three-day larva. Total length mm. The structural development of the larvae is illustrated in Figures 6-9. A brief description of this development follows: In the 24-hour larva (Figure 6) there is a slight constriction of the upper lobe of the caudal fin fold. The lepidotrichia of the caudal fin fold can be seen as can the small pectoral fins near the dorsal edge of the yolk sac. The oil globule is still fairly large but is more oval than spherical in shape. The head region is characteristically bent over the yolk sac at this stage, but very soon afterwards straightens out (Figure 7). In the 36-hour larva (Figure 7) there is further constriction of the caudal fin fold posterior of the anal pore and the lepidotrichia of the caudal fin fold are more numerous and longer. The pectoral fins are noticeably larger and can be seen in outline under proper illumination. The cerebral hemispheres are very marked. The yolk sac is not much smaller in proportion to the body length than in the 24-hour larva. In the 48-hour larva (Figure 8) there is a marked decrease in the size of the yolk sac, but the oil globule still remains comparatively large. The pectoral fins are much larger and can.
