The remaining thoracic appendages are larger than in the preceding stage but are otherwise un- changed. Occasionally the rudiments of the second thoracic limb may be discerned as a small naked process. The segmentation of the thorax is clearly visible. The abdomen now has five segments and a telson. The developing uropods can be seen within the integument of the telson. The telson retains the three pairs of postero-lateral and one pair of ventro- lateral spines of the previous stage, but now has seven terminal, serrated 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 Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
