. 0-25mm Fig. 24. Nematoscelis megalops. a, third calyptopis, lateral view; b, telson and uropods. The second antennae and thoracic appendages have not changed. There are now six abdominal segments and a telson. The abdomen bears no appendages. The lateral uropods of the telson are now developed and spinose. The outer ramus of the uropod is somewhat longer than the inner and its outer margin is produced as a small, strong tooth. The remaining armature of the telson is unchanged. A dorsal view of this stage can be seen in Frost (1935), and is, therefore, not figured here. She does not, however,

This can be seen even in lateral view.
