Stenopid III. St. 1580. Stenopid IV (Fig. 9) 'Atlantis' St. 1121 Stage IX?. Length 11-6 mm. (rostrum 2 mm.). Rostrum extending just beyond peduncle of antennule. Supra-orbital spine minute. Carapace deeply grooved in front and behind, rounded behind. Abdominal somite 3 with large dorsal spine. Somites 1-5 with pleural spines, those of somite i very large, and all pointing slightly forwards. Somites 5 and 6 with small dorsal spine, the latter without lateral spine. Legs 1-3 chelate, very large. This is no doubt the last larval stage, and contrasts very much in size with the equivalent stage in S. hispidus. Stenopid V (Fig. 10) St. 1576 Stage VI ?. Length 16 mm. (rostrum 5-3 mm.). Rostrum longer than antennules, smooth. Supra-orbital spines very small; carapace with strong spine at posterior angle. Abdominal somites 1-5 with pleural spines, directed backwards on somite i and forwards on the others; somites 3, 5, 6 with dorsal spines, the former large. Somite 6 without pleural or anal 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.
