. Fig. 2. Nyctiphanes capensis. Ovigerous female. Nauplius. The nauplius stage (Fig. 36, c) is passed within the egg-sac. The specimens shown in the figure were removed from the unruptured egg-sac of the female. The length of the two specimens examined was 0-42 mm. each. The larva is simple and egg-shaped. It has two small processes at the posterior end, each flanked by one smaller process. The first antenna is uniramous with three terminal setae. The second antenna is biramous, the rami with four and five terminal setae. The mandible is bud-like and naked. Pseudometanauplius. Only one specime


. Fig. 2. Nyctiphanes capensis. Ovigerous female. Nauplius. The nauplius stage (Fig. 36, c) is passed within the egg-sac.

The second antenna is biramous, the rami with four and five terminal setae. The mandible is bud-like and naked. Pseudometanauplius. Only one specimen of this stage was found (Fig. 3 d, e). It was removed from the ruptured egg-sac of a female. It is probable that the rest had already hatched out. Length of specimen 0-48 mm. The carapace is oval in dorsal view. The first antenna is unchanged. The second antenna is the same as in the nauplius stage. A median eye has appeared. The anterior lip and buds of three metanaupliar limbs have appeared. There is now a short tail with one pair of postero-lateral and two pairs of terminal spines. The carapace, mandibles, anterior lip, limb-buds and tail are covered by a thin skin.
