Second antenna: — The exopodite is very much lengthened relat-ively; its two proximal joints especially are considerably longer than the correspondingjoints in the female. The relation between the lengths of the joints is shown by thefollowing figures: 3 (shell 1,7 mm. long) = I : II : (III —IX) -: 34 : 17 : 22. •?o^ olfi TAGE SKOGSBERG For the sake of comparison the corresponding figures are given for the female, calculatedon tlie same scale: ? (shell mm. long) = I : II : (III -IX) = 18,5 : 4 : 16. The second joint is about as long as four or five of the following joints; the third to theninth joints are, as in the female, all of about the same length. The fourth to the ninth joints.
