The second pair are composed of five articles, the terminal article being tipped with hairs. The seven segments of the thorax are distinct and taper gradually, becoming successively narrower. The six abdominal segments are distinct. They taper gradually but rapidly to the small terminal segment which is posteriorly produced in a long, narrow process, which is a little longer than the basal part of the segment. The uro- poda consist of a small branch on either side of the sixth or termi- nal segment and are attached at the place where the basal part of the segment gives rise to the long, narrow terminal process. There are five pairs of single- branched pleopoda, a pair for each of the first five abdominal seg- ments. They are in the form of narrow, elongated sacs, rounded at the extremit}^ and attached, one on each side, close to the lateral margin of the segments. The first abdominal segment bears on the dorsal surface two large rounded papilliv, one on either side, close to the lateral margin. There arc seven pairs of prehensile legs. Dr. W. T. Caiman says that he thinks it is characteristic for the males and females to be attached separately to the host. Only in one case did he find a male attacluHl to the female. The label accompany- ing one male sent by Doctor Caiman reads: ''Found on the second pleopod of ;.
