on outer distal margin, inner margin has strong rows of marginal spines almost to end of inner plate, below these a further marginal group of several spines; group of 3 serrate-tipped surface spines at proximal merus level Basos has a few stout marginal spines ischium, merus and carpus each 2 or 3 spines on outer distal angles; merus wider than long, about 3 spines on inner distal angle; carpus subsquare, strongly marginal field of serrate-tipped spines on inner margin distal ⅔ about 4 spines below propod inner proximal angle; propod longer than wide, serrate-tipped spines on inner margin distal 2/1 completely masking end; obliquely transverse row of about 5 strong spines on surface just below end Dactylos not apparent.

Gnathopods. First: Sideplate subtriangular. strong spines on ventral margin. Basos posterior margin convex, width ⅓ length, posterior and both anterior margins have strong spines, also distal angles and proximal surface. Ischium about ¼ basos length; merus subtriangular, strong spines on posterior surface and margin; carpus subtriangular, posterior and distal margins spined strongly, one particularly long spine reaching almost to end of propod, a small scabrous pellucid lobe medially on posterior margin. Propod ⅔ basos length, anterior margin has about 5 groups of short spines; posterior margin and surface with strong spines, posterodistal angle expanded in scabrous lobe: a strong curved spine extending anteriorly from dactylos base, palm ½ propod width, not clearly defined, has a few small spines. Dactylos considerably longer than palm, slender, curved. Second: Sideplate subsquare, spined ventrally and posteriorly, posteriorly excavate. Gills anchor-shaped. Basos proximally constricted, posterior margin convex, spined; both anterior margins and surface spined. Ischium subrectangular, has spine medially on posterior margin, posterodistal angle a few small spines. Merus has 2 or 3 minute spines on margins and surface. Carpus triangular, ½ merus size. Propod as long as basos, greatly expanded, greatest width ⅔ length, ovate; palm oblique, nearly twice length of posterior free margin; triangular tooth near dactylos base, palm has small stout spines; long dactylos slightly expanded medially.

Peraeopods. First: Sideplate subsquare or slightly wider than deep, spined posteriorly and ventrally, posteriorly excavate. Basos width ⅓ length, margins spined, a few surface spines. Ischium small, subsquare, posterodistal angle spined. Merus ⅔ basos length, widening slightly distally, margins and posterior surface spined. Carpus ⅔ basos length, a few spines anteriorly, posterior margin and surface have strong spines. Propod slightly longer than basos, margins and surface spined. Dactylos long, curved at tip, single spine on inner margin. Second: Side-plate trapezoid, wider than deep. Short stout dactylos has notched inner margin. Segments slightly shorter than in Pr. 1, otherwise the same. Third: Sideplate anterior lobe much the larger, posteriorly and ventrally spined. Posterior lobe strongly spined posteriorly, spines continuing a little anteriorly. Basos nearly as wide as long, anterior margin has a few single spines, posterior has many short stout spines, is convex, surface has a few medial spines Ischium anterodistal angle strongly spined Merus stout, width ½ length, length slightly more than ½ basos; widening slightly distally, anterior margin has about 4 groups of 2 or more spines, distal ones almost ½ merus length; posterior has similar groups of shorter spines Carpus as long as merus, narrower, linear, somewhat similarly spined. distal spines almost ½ propod length Propod slightly longer than merus, width ¼ length. 4 or 5 groups of spines on each margin, the strongest anteriorly. Dactylos more than ½. propod length, stout, slightly curved, single seta on inner margin. Fourth. Sideplate spined ventrally and posteriorly. Basos width ⅔ length, anterior margin and surface have strong spines, posterior many short stout ones Ischium sub-square, anterodistal angle spined. Merus ⅔ basos length, width ½ length, a few spines posteriorly and on distal angle, anterior margin and surface have numerous strong spines Carpus linear, slightly longer than merus, margins have several groups of spines, strongest spines anteriorly Propod as long, margins almost serrate with groups of short to very long spines Dactylos as in Pr 3 Fifth. Basos slightly wider than long, extends down posteriorly to overlap most of merus margin; anterior margin and surface have numerous short stout spines; posterior has fewer but stronger spines than in Pr 4: margins convex, especially posterior Ischium small, wider than long, strongly spined anteriorly Merus stout, subtriangular, widening to 2/4 length, margins spined and irregular Carpus as long as basos, both anterior margins have a few spines, posteriorly expanded to tremendous oval cup, between 2 and 3 times as wide across as carpus anterior margins are long and not quite twice greatest length of cup; posterior margin of cup has numerous small spines Cups form compact sphere when both peraeopods opposed Propod and dactylos as in Pr 4.

Epimeral Plates First: Anterior margin has about 5 strong spines, posterior 3, angle not strongly defined Second. Subrectangular, anterodistal angle rounded, one spine set back a little from anterior margin; posterodistal angle right-angled, posterior margin straight, has about 6 stout spines Third. Posterior margin has about 5 spines.

Pleopods Rami as long as peduncles, non-segmented, but have paired marginal plumose setae. Peduncle outer margin and outer ½ of surface have numerous spines: 1st pleopod inner margin has 2 proximal and 3 distal spines, 2nd pair have 3 distal spines; 3rd have row of spines on inner surface.
