X Fig. 13.— Spherillo testudinalis. Head and first three thoracic segments. (Ventral view). 16. X of the segment in the form of a small cleft on the posterior margin a short distance from the lateral margin. On the underside the coxo- podite is separated only posteriorly in the form of a tooth. The six following segments of the thorax are subequal in length. The coxo- podites of the second segment are small, but quite prominent on the underside, and are in the form of a sharp tooth. The coxopodites of the third and fourth segments are small and are repre- sented on the upper part of the underside of the segments by a thickened ridge. In the last three segments the coxopodites are large and prominent and are in the form of thickened processes on the underside. The first five segments of the abdomen are about equal in length. The lateral parts of the first two are covered by the last thoracic segment. The lateral parts of the third, fourth, and fifth segments are expanded and the third segment has distinct coxopodites on the underside similar to those of the preceding thoracic segments. The terminal abdominal segment is tetragonal, wider at the base than at the apex, which is truncate, and contracted in the middle. The uro- poda are short, not reaching beyond the extremity of the last abdomi- nal segment. The basal article is large, wide, truncate at the apex, and occupies all the space between the last segment of the abdomen and the lateral parts of the preceding segment. The outer branch is small, conical, and placed on the dorsal side of the basal article in a groove which extends to the middle of the dorsal side. The inner branch is small and narrow and does not c^uite reach the ex- tremity of the last ab- dominal segment on the underside. In color it is dark brown with patch
