MALE. In the largest specimen the length of the body is lOmm. ; seen from 

 below (flg. 3g), it is short and broad, only a little longer than broad, its circumference is 

 nearly rhombic, with broadly rounded angles. The second specimen is of the same length, 

 but is considerably more slender, though scarcely as slender as the male of the following 

 species (S. Metop<e). So the male is rather small compared with the female (fig. 3 a, 

 where a male is marked m). The head is not a little larger than the trunk (fig. 3h). The 

 front is somewhat produced, its anterior margin naked, slightly convex in the middle, slightly 

 concave towards the sides somewhat in front of the antennulse. Antennulae, antennae, mouth 

 and maxillulae essentially as in the female. The basal joint of the maxillae has a short 

 conical process on its posterior side. The maxillipeds of medium length; their basal joint 

 has several stripes and spots covered with hairs, and their inner margin an incision and 

 two considerable, shortly conical processes, which can only be seen distinctly when looking at 

 the maxilliped from in front (fig. 3 k) or from behind, so that all its joints present themselves 

 on the same plane; the terminal joint has a small spine inside its point. The sub-median 

 skeleton has its first pair of processes developed into short conical taps which turn outward, 

 one behind the base of each of the maxillae ; posteriorly, between the bases of the maxillipeds, 

 the skeleton takes the shape of a pretty considerable, somewhat raised area, the median 

 part of which extends into a broader plate, cut otf posteriorly ; laterally are found the second 

 pair of processes which are shaped like long narrow cones, a little curved near their base 

 and turned straight backward. The lateral margin of the head provided with a row of 

 moderately long hairs, and from its posterior angle the hair-covering is continued as a belt 

 upward and rather obliquely backward across the side and the back. The dorsal part 

 and the upper lateral parts of the head show hollow spaces beneath the skin. The dorsal 

 surface of the trunk with a broad and pretty long, naked area, in front of which is found 

 the above-mentioned, moderately narrow belt of hairs of medium length; the lateral surfaces 

 of the trunk, its posterior extremity and the greater part of its ventral surface are closely 

 covered with hairs of medium length. The first pair of trunk-legs of about medium length; 

 the basal part broad; the inner branch is a short knot, the outer branch of medium length 

 and ending in two setae, one of which is almost half the length of the body, the second 

 about a tliird or scarcely a third the length of the first one, besides, the branch has on its 

 outer side a conical process which ends in a short seta; the terminal seta of the inner 

 branch is scarcely the length of the shorter terminal seta of the outer branch. The second 

 pair of legs are short, the inner branch with one short and one extremely long terminal 

 seta, which almost exceeds in length the one on the outer branch of the first pair of legs; 

 the outer branch is a conical tap terminating in a tliin seta which is a little shorter than 

 the leg. The terminal seta of the caudal stylets not more than about thrice the length 

 of the stylet, and the same length as, or shorter than the secondary seta of the outer branch 

 of the first pair of legs.
