The third pair of legs is like those of the preceding species, but the outer-edge spinous lamina of the second basipodite is wanting, and the posterior surface of the third basipodite has a patch of strong spines, wanting in the second pair. The fourth pair of legs is distinctly granular on the anterior sur- face, but has fairly long spines in a longitudinal area on the two inner segments in addition to the granulation; on the posterior surface of the two distal outer segments as well as on the distal inner one a few short spines are observed; on the posterior surface of the second inner segment a transverse row of 8 long spines is found. The fifth foot agrees fairly well with Scott's and Farran's description, but the articulation is very indistinct. The labrum is comparatively slightly produced in front (PI. VII fig. 12 a). The arrangement of setae on the anterior surface is rather characteristic; in front a median group of fairly long bristles, 3—4 deep continued into a lateral group of a number of shorter hairs, extending laterally to in front of a posterior lateral group of densely placed hairs. In the middle, later- ally partly fused with mentioned anterior group, a transverse series of comparatively few short setae. Add to this a marginal group of nu- merous bristles. The oral surface of the labrum (PI. VII fig. 12 b) shows some similarity to S. validus, and in a less degree to S. globiceps; the granular area around the first median circular spot is only small; the lateral marginal and the first lateral group form a fairly long oblique group, medially consisting of granules, and converging towards the second median circular spot; the following lateral groups are in the main like the structures in the preceding species. The arrangement of setae around the "lamina labia lis", and upon the labial lobe
