Maxilliped: Inner plate subrectangular, reaching carpus base, end margin straight like median but rounding to convex outer margin, 4 small teeth along inner ½, a few plumose setae down cleft, several along end margin and between and below teeth. Outer plate almost reaching end of carpus, inner margin slightly convex, outer convex and rounding to distal margin which has 5 strong plumose setae; inner margin has about 6 teeth, with narrow bases but widening distally; fine setae in ones and twos along margin almost to base. Inner portion of basos distal margin fringed with several long setae; ischium wider than long, 5 or 6 long setae on rounded inner distal angle. Merus outer margin twice length of inner, slightly longer than ischium, as wide as long, single strong seta on inner distal angle. Carpus narrowing slightly distally, greatest width ¾ length, length 5/3rds merus; inner margin fringed with long setae. Propod width almost ½ length, length ¾ carpus, long setae on distal margin and distal ½ of inner margin, a few on surface. Dactylos narrowing to long slender terminal nail, length ⅗ propod, 3 or 4 setae distally on inner margin, nail as long as dactylos.

Gnathopods. First: Sideplate small, as wide as deep, basically trapezoid, a single seta anterodistally. Basos proximally constricted, greatest width slightly less than ½ length, 1 or 2 small marginal setae, 2 or 3 strong setae at posterodistal angle. Ischium subrectangular, ⅓ basos length, a few setae at posterodistal angle. Merus greatest width ½ length, length ½ basos; slightly convex anterior margin contiguous with proximal ⅓ of carpus posterior margin; 3 groups of strong setae on posterior margin, a few distally on surface; posterodistal angle produced downwards a little in acute triangular process. Carpus subtriangular, distal width ⅔ length, as long as basos, anterior margin slightly convex, a tuft of setae on distal angle; posterior free margin slightly convex, fringed with strong setae, several long setae down surface medially. Propod subtriangular, less than ¾ basos length, width subequal with posterior margin which corresponds to palm; margins slightly convex, about 5 groups of 2 or more long setae on anterior surface, several short setae and a few longer ones on posterior margin which is finely serrate; stout, slightly curved dactylos as long as posterior margin, inner margin finely serrate, 2 fine setae near tip. Second: Sideplate small, ovate, wider than deep, ventral margin frilled and crimped. Basos proximally constricted, posteriorly convex, distal width ⅓ length, a few fine setae on margins. Ischium as wide as long, ¼ basos length, Y-shaped in cross-section with arms of Y forming anterior margins and propod sitting back on concave surface between them. Merus small, ovately subtriangular, width ⅓ length, length ½ basos, tuft of setae on posterior margin. Carpus greatly expanded, widening distally, anterior margin slightly convex, as long as basos; distal width ¾ carpus length; posterior margin more or less straight, posterodistal angle produced forward below propod as strong tooth almost (but not quite) to dactylos; inner margin of tooth with smaller parasitic tooth; long slender setae on posterior margin, a few on surface. Propod, slightly convex anterior margin barely shorter than carpus, a few fine

setae; posterior margin more or less straight with 1 or 2 small concavities proximally, margin somewhat carinate with irregular fringe of long fine setae; proximal width ½ length, narrowing a little distally. Stout curved dactylos proximally a little constricted, ¾ basos length, apex stout, slender setae on margins, a strong transverse fringe of setae just below tip.

Peraeopods. First: Sideplate ovate, slightly deeper than wide, a few long setae on ventral margin. Basos ovate, glandular, greatest width ⅔ length, margins strongly convex, a few setae along anterior and at posterodistal angle. Ischium subrectangular, longer than wide, ¼ basos length, a few setae on posterodistal angle. Merus piriform, 3 or 4 strong setae on convex anterior margin; posterior straight, setose; greatest width ⅔ length, length ⅖ basos. Carpus ⅔ merus length, much narrower, a few setae on posterior margin and anterodistal angle. Propod width ⅓ length of anterior margin which is almost merus length, a few fine setae on posterior margin and on anterior distally. Strong curved dactylos ⅔ propod length. Second: Similar. Third: Sideplate very difficult to dissect out with rest of appendage—in all these specimens Pr. 3 has broken between sideplate and basos. Sideplate, anterior lobe ovate, deeper than wide, strongly convex ventrally with a number of long setae; posterior lobe extremely small, ovate, a long strong spine at ventral angle; anterior lobe much deeper than that of Gn. 2. Gill ovate, almost as large as anterior lobe. Basos expanded, margins a little convex, narrowest proximally, a few setae on anterior margin, posterior produced downwards in rounded lobe with concavity between lobe and ischium, distal width as great as length; several strong setae along posterior margin. Ischium wider than long, ⅓ basos length, posterodistally produced backwards in small lobe; a few setae on distal angles. Merus widening a little distally, almost as long as basis, width ½ length, several setae on margins, groups at distal angles. Carpus almost as wide as long, ½ merus length; slightly ovate, strong tufts of setae on distal angles. Propod slender, ½ basos length and ½ carpus width, a few long strong setae distally. Strong slightly curved dactylos. Fourth: Like Pr. 5, shorter. Fifth: Basos ovate, tending to subrectangular; width ⅔ length; posterior margin more or less straight, a few setae on margins. Ischium ⅓ basos length, longer than wide, seta anterodistally. Merus barely widening distally, as long as basos. width ⅓ length, 3 or 4 groups of 1 or 2 setae along each margin. Carpus ⅔ basos length, width ½ length; 1 or 2 fine setae ½ along each margin, strong tuft at each distal angle. Propod slightly longer than basos, width ¼ length, 5 or 6 single setae on anterior margin; 3 groups of setae along posterior. Stout dactylos nearly ½ propod length, small tooth on posterior margin.

Epimeral Plates. Ovate, ventrally convex, lateral margins almost parallel; margins smooth with perhaps a single small seta on posterior margin.

Pleopods. Two coupling spines, rami of 8–9 segments, rami and peduncle almost subequal, inner ramus slightly the longer.

Uropods. First: Rami subequal, shorter than peduncle; peduncle inner dorsal margin slightly convex, distal ½ finely toothed, with 4 strong spines; outer dorsal margin has 3 small spines. Rami with both margins finely toothed; inner ramus has 4 spines on inner margin, 1 large and 1 small end spine; outer has 2 spines on inner margin, 3 on outer, about 3 short and 1 long spine at end. Uropod 1 reaching further than uropod 2, uropod 2 further than uropod 3. Second: Rami subequal, shorter than peduncle, long strong spine on peduncle inner distal angle. Rami margins finely toothed, inner ramus has single spine ½ along inner margin.
