Scale indicates for A, B. for C-F. segments. No eyes. Maxilliped (Fig. 4C) with very irregular outline. Posterior ventral border of head (Fig. 4D) with long pointed lateral projection, ir- regular blunt process medial to it. Pereon surrounding head, first two pereomeres obliterated centrally, first five surrounding head, sixth longest. First oostegites (Figs. 4E, F) rounded anteriorly, with dentate internal ridge, sharply angled falcate posterolateral point. Most of other oostegites damaged or missing, so size, shape and position un- known. First five pereopods with prominent coxal plates, sharply reflexed. reduced in size (Fig. 4G); last two pereopods lacking coxal plates, more or less straight, larger (Fig. 4H). Last two pereomeres (Fig. 41) with medial ventral tubercles near anterior mar- gins. Pleon nearly as long as pereon. gradually tapering posteriorly, of six pleomeres. Lateral plates and pleopodal rami (Fig. 41) all about the same size, ovate in outline; evidently pleopods and lateral plates lost from fourth and fifth pleomeres by damage. Uropods uniramous. oval, each nearly as large as whole last pleomere. extending far posteriorly from that pleomere. Tiny posterior point between uropods. Redescription of allotypic male [Fig. 5).—Body length maximal body width , head length pleon length Sides of body nearly parallel, all segments clearly separated (Figs. 5A. B). Head semicircular, narrower than pereon. No eyes. Antennae (Figs. 5C, D) of three and five seg- ments, respectively. Pereon broadest, but only slightly so, across fourth pereomere. All pereomeres separated by slight antero- lateral indentations. Pere
