Pseudorostral lobes much and sharply produced in front of the small eyeless eyelobe; antero-lateral corners subquadrate with denticulate margin , stronger above than below. Carapace strongly beset with powerful teeth, of which 2 are especially so on each side of the frontal lobe and one below it; besides there is a close covering of microscopic denticles and the lower margin is denticulate. Pedigerous segments 1 and 2 short, with side-plates beyond width of carapace. All the pedigerous segments and first 3 of pleon have medio-dorsal pairs of warts or teeth, the latter form on the last 3 pedigerous and first 2 pleon segments. On first 5 segments of pleon a median dentate carina encreasing on successive segments. , ,• ^ V Telsou begins laterally dentate, narrows before the middle, ^i y'lN with about 9 pairs of lateral spines and a stronger apical pair. Antenna 1 short aiid weak. Branchial leaflets about 20. Maxilliped 3, 2^ narrower than 3<^ or 4:^^. Peraeopod 1 Avith strongly dentate 2"'^ joint, and a medial distal tooth on 3<i and" A^^^ joints. Peraeopod 2, S^h joint not so long as 6*1' and 7^^' combined, 6*^^ little shorter than 7^^ Peduncle of uropods about as long as the telson with some It) spines on the medial margin. Rami about half as long as the peduncle (text), exopod with 1^* joint much shorter than 2"*^. slightly longer than the 1-jointed endopod which has about 11 spines on its medial margin.
