The larvae of the latter occur in the higher layers of water, just as is the case with A. multispina. Acanthephyra Edw. jltispma ( Coutiere ) purpurea Edw. Scale refers to length of Carapace. Fig. 475. What has just been said illustrates the conditions on the northern section from Newfoundland to Ireland, and if we examine the material from the stations farthest south in the Sargasso Sea, we are confronted with exactly the same difference that we encountered in the case of the species of Cy clot hone, namely, that the same forms descend to greater depths in the south than they do in the north ; the larger individuals of Acanthephyra purpurea, for instance, occur at depths.
