. Fig. 88. Syrrhoe nodulosa, a. General view. b. Dorsal view of pleon segments 1-4. ovoid, dorsally not quite contiguous. Peraeon segments 1 and 2 very short dorsally, together equal to 3rd segment, following segments increasing in length. Back rounded. Posterior margins of segments 4-7 more or less raised, prominent and, on segments 6 and 7, produced in a short medio-dorsal tooth, that on segment 7 with a tubercle in front of it. Segments 6 and 7 each with a blunt but well-marked horizontal keel just above junctions of side-plates; a similar keel or swelling also on segments 4 and 5 in

Posterior margins of segments 4-7 more or less raised, prominent and, on segments 6 and 7, produced in a short medio-dorsal tooth, that on segment 7 with a tubercle in front of it. Segments 6 and 7 each with a blunt but well-marked horizontal keel just above junctions of side-plates; a similar keel or swelling also on segments 4 and 5 in some specimens. Side-plates as in crenulata. Pleon segments 1-3 each with a medio- dorsal blunt tubercle, followed by a projecting tooth on the hind margin, which seen in dorsal view is notched; whole posterior margin denticulate; a blunt horizontal keel on each segment continuing the line of those on peraeon segments 6 and 7; postero-inferior angle of segment 3 quadrate. Pleon segments 4-6 dorsally rounded, posterior margin of 4 denticulate. Telson elongate, cleft almost to base, lobes contiguous, tapering to acute, minutely notched apices. Antenna 1, ist and 2nd joints subcqual, upper margin of ist sharply keeled, setose, distal margin on inside with upcurved tooth, 2nd more slender, 3rd just over half
