Integument with elongate or scale-like pits, arranged horizontally in front part of body, gradually becoming oblique and then transverse on the pleon segments; still finer scale-like markings between the major pits. Eyes subcircular, rather large, reddish (as preserved). Post-antennal angle of head acutely produced. Side-plate 1 widening below; all the side-plates serrulate on lower margins. Peraeon segment 7 and pleon segments 1 and 2 each with a dorsal tooth, Fig. 97. Oradarea tridentata, a. Side-plate 1 with sculpture, b. Side-plate 2. c. Telson with margin further enlarged, d. Telson of feebly notched variety, e. Pleon segments 2 and 3. /. Dorsal view of tooth on pleon segment 1. g. Gnathopod 1. h. Gnathopod 2. which is acute when seen in dorsal view. Pleon segment 3 with a raised carina, rounded in profile. Postero-inferior angle of pleon segment 1 with a short acute point, of seg- ment 2 with a strong, slightly curved point, of segment 3 with an upturned acute point some little distance above the lower margin, with a deep semicircular notch above it. Telson subtriangular, the lateral margins narrowing rather abruptly at about two-thirds the length, the apical margin entire or feebly notched, each notch with a setule. Epistome and upper lip gibbous, subcarinate medially. Antenna 1 with a minute 1-jointed accessory flagellum. Gnathopod 1, 6th joint broader than in novoe-zealandiae, slightly though distinctly longer than 5th, not narrowing distally, palm slightly oblique, concave, defined by a blunt angle and about six spines (four on one side, two on the other).
