. Fig. 50. S. vigilax. Petasma. a, specimen of 1094 mm.; b, 14 mm.; c, 16-3 mm., left, from inside; d, the same, from outside. Stage 2 retains all the spines of stage i almost without diminution. There seems to be much variation in the degree to which the exopods of the legs are retained. Of three specimens moulted from the Acanthosoma one has no trace of exopods, one has minute vestiges, while the third has long exopods even on legs 4 and 5. Pleopods long, uniramous. Setose part of uropod rather more than half length of bare part. Colour. Body largely colourless, but with bright red patches i
