Peraeopods. First: Sideplate, basos and ischium much like Gn. 2. Merus constricted proximally, nearly basos length, width more than 1/3 length, anterior margin convex, a few long setae on slightly produced anterodistal angle, long slender setae along posterior. Carpus 1/2 merus length, width 2/3 length, narrowing a little distally, oblique row of long setae across posterodistal surface; posteriorly fringed with long setae, stout apical spine reaches 3/4 along propod. Propod width less than 1/3 length, slightly longer than carpus, 10 strong seta-tipped spines on surface and posterior margin. Stout spine-like dactylos nearly 1/2 propod length. Second: Sideplate not greatly deeper than wide, angles broadly rounded to convex ventral margin which has only 2 or 3 setae; otherwise like Pr. 1. Third: (Damaged.) Sideplate posterior lobe ovate. Basos oblong-ovate, narrowing slightly distally; width 3/5 length; anterior margin slightly concave with short fine setae proximally, about 4 long setae on distal 1/2, arc of 5 at angle; very small single setae along and not extending past convex posterior margin giving cracked appearance. Ischium wider than long, 1/3 basos length, strong arc of long setae anterodistally. Merus piriform, widening strongly distally, length 2/5 basos, as long as distal width; groups of 1, 2 and 5 stout spines on anterior margin, long setae all along; groups of 3 and 5 stout spines on posterior margin, each group with a long plumose seta. Carpus subrectangular, width 2/3 length, length 1/2 basos, 4 groups of 3 to 5 stout spines on anterior margin, outermost the longest, long plain setae and a few long fine plumose setae on margin; 3 groups of 2 to 5 stout long spines posteriorly, several long fine plumose setae especially distally. Fourth: Basos ovate, width 3/5 length, short marginal setae on strongly convex anterior margin proximally, long setae singly and grouped on distal 1/2; slightly convex posterior margin has cracked look; posteriorly expanded downwards a little as lobe. Ischium 1/6 basos length, wider than deep; strong groups of setae anterodistally. Merus nearly 1/2 basos length, anteriorly damaged, several long, finely plumose setae and 3 groups of 2 to 4 strong spines on convex posterior margin. Carpus damaged but with several marginal long setae, groups of 5 or more strong spines on distal angles, 1 or 2 long fine setae. Propod width about 1/6 length, length 2/3 basos, margins indented with 4 groups of 2 or 3 strong spines anteriorly, posteriorly 4 groups of 4 or 5 spines, each group with single long seta. Slender dactylos more than 1/2 propod length. Fifth: Basos greatly expanded, anterior margin straight, 2/3 greatest width, as wide as greatest length; posterior margin greatly convex, expanded downwards and outwards almost to carpus; about 10 distinct serrations on margin medially, merging distally into cracked appearance. Ischium subsquare, barely more than 1/4 length basos anterior margin, setae on anterodistal angle. Merus nearly 1/2 length basos anterior margin, 4 groups of slender spine-setae anteriorly, 2 or 3 fine setae posteriorly, long spine-seta on distal angle. Rest damaged.

Epimeral Plates. First: Trapezoid, fine setae distally on straight anterior margin, anterodistal angle bluntly obtuse, ventral margin rounded to posterior. Second: Subrectangular, groups of fine setae medially on anterior margin, rounding to straight ventral; dorsal margin straight and almost right-angled to posterior, row of about 7 long plumose setae on anterior 1/2 of ventral surface and parallel to ventral margin. Third: Wider than deep, subrectangular, angles
