Pilosity: The first and second joints have abundant groupsof short, exceedingly fine, stiff hairs — only just suggested in the adjoining figure — the antero-distal part of the second joint seems, however, to be always without hairs. There are no hairsalong the distal boundary of this joint. Second a n t (> n n a: — Tlie j) i- o t o p o d i t e has distally a very short bristleon the inside close to the exopodite.

The endopoditeis distinctly three-jointed; its distal bristle is slightly longer than the stem. Mandible: — Protopodite: Coxale: The scythe-shaped process (figs. 8,9):The part distally of the main spine narrows uniformly and gently into a fine point; its ventraledge is even and rather decidedly convex. The distance from the point of the process to themain spine is about as long as or somewhat longer than the distance from the latter
