Body colourless in stage 2 except for a red spot at base of telson and in each arm of it. In stage 3 there is red in the antennular peduncle, in both branches of the antenna, and in the arms of the telson fork. Acanthosoma i (Figs. 13 c, 14 a). Length 6-o mm. Rostrum 1-4 mm.

Body colourless in stage 2 except for a red spot at base of telson and in each arm of it. In stage 3 there is red in the antennular peduncle, in both branches of the antenna, and in the arms of the telson fork. Acanthosoma i (Figs. 13 c, 14 a). Length 6-o mm. Rostrum 1-4 mm. Rostrum a little longer than the antennule, about equal to length of carapace. Of this stage we have only two specimens and in one of them the spine at the base of the rostrum is very long and spinulose (Fig. 13 c), whereas in the other it is minute (fig. 14 o), as it js shown in Hansen's figure of stage 2. Carapace about i^ times as long as Fig. 13. S. lemiiremis. a, Elaphocaris 2; b, Elaphocaris 3; c, Acanthosoma i. One pair of short lateral spines with spinules; hepatic and dorsal spines small. Abdominal somites with dorsal spines rather small; spine of somite i smallest, smooth, 3-6 longer, with spinules. Lateral spines small, slender and smooth or nearly so. No median ventral spines. Telson i\ times as long as wide, without lateral spines; arms very long and slender, reaching beyond uropods, and with six outer and five inner spines. Eye large, asymmetrical, the greatest width more than one-half total length, and total length nearly one-sixth length of body. Antennal scale six times as long as wide, with four apical and one outer seta; endopod longer than scale, with two very small inner spines. Labral spine very small. Pleopods minute. Endopod of uropod distinctly wider.
