. Fig. 5. Serolis kempi, , ^: x 6. Description. This collection contains adult males and females, the latter in both the breeding and non-breeding phase. An adult male measures 15 mm. in length and 14 mm. in breadth, and an adult female 15 mm. in length and 13 mm. in breadth. The body (Fig. 5) is broadly oval, slightly longer than broad and slightly keeled. The head is about one and a half times as wide as long, shield-shaped in outline, with a very small rostral process between the bases of the antennules: behind this process a well-marked trans- verse ridge extends laterally to the side
. Fig. 5. Serolis kempi, , ^: x 6. Description. This collection contains adult males and females, the latter in both the breeding and non-breeding phase. An adult male measures 15 mm. in length and 14 mm. in breadth, and an adult female 15 mm. in length and 13 mm. in breadth. The body (Fig. 5) is broadly oval, slightly longer than broad and slightly keeled. The head is about one and a half times as wide as long, shield-shaped in outline, with a very small rostral process between the bases of the antennules: behind this process a well-marked trans- verse ridge extends laterally to the sides of the cephalosome. The portion of the head between the eyes is convex and divided into two areas by a slight groove; an anterior one bearing two rounded prominences and a posterior larger one, divided into three oval prominences, the central of which is smaller than the two lateral: this area extends for some distance behind the eyes. The eyes are large, about half the length of the head, reniform in shape and containing black pigment. The second thoracic somite is fused with the head as in all the species of Serolis. The lateral portion bears two transverse ridges on each side, a small anterior one which is continuous with the anterior one already described on the head, and a second which extends laterally from near the posterior angle of the eye, a point about half-way between the anterior and the posterior margins of the cephalosome. Each of the third to the seventh thoracic somites is produced into a short but distinct median dorsal spiniform process; that of the fifth somite is considerably larger and longer than those of the other somites and projects backwards to about the middle of the sixth somite. Low eminences are present, one on either side of each of the thoracic somites, just within the junction of the tergum with its coxal plate. The coxal plates are well developed and are sparsely fringed with short hairs, those of the first three free somites are marked off
