Gnathopods. First: Subsquare except that anterior margin narrows somewhat proximally, 4 fine setae anterodistally. Basos proximally constricted, width ⅙ length, anterior margin duplicated, one of the margins with 8 or 9 long setae, the other naked; posterior has long setae proximally, tufts of short fine setae distally. Ischium subsquare, ⅙ basos length, one of 2 anterior margins produced distally to flanged lobe. Merus sublanceolate, posterodistal angle produced downward 5 with a blunt spine, 3 groups of setae on distal ⅓ of posterior margin, width ½ length, length not quite ⅓ basos, anterior margin contiguous with carpus proximal margin. Carpus a little shorter than merus, anterior margin convex and naked, distal sinuous, posteriorly produced in spoon-shaped lobe between merus and propod down latter almost as far as palm-defining spine; outer distal and end margins of lobe strongly setose; 3 parallel rows of setae on outer surface. Propod ovate as long as basos, width ½ length, anterior margin naked, row of about 6 setae on anterior surface, slightly convex; posterior strongly convex, interrupted about ⅓ by defining spine, palmar margin has profuse row of alternately long and short spine-setae on outer margin, short spines on inner, spine-setae very finely plumose distally and with 2 or 3 fine teeth on one margin; sparser parallel row of simple setae on surface, small projection with 2 spines at level of other palmar spine; long slender convex dactylos as long as palm, 8 inset teeth on inner margin proximally. Second: Essentially similar; sideplate ovately subtriangular, barely longer than wide, distally narrowing and rounded with 2 or 3 fine setae. Basos as before, anterior margin naked; ischium posterodistally setose, longer than wide, ¼ basos length. Merus ⅓ basos length, nearly twice carpus length; carpus has 5 rows of setae on outer margin; propod a little longer than basos, width more than ½ length, palm medially emarginate, the 6 or 7 small spines on inner margin of distal section of palm set in pockets (Fig. 116). Dactylos inner margin has 16–17 teeth. Gills large, simple.

Peraeopods. First: Sideplate comparatively long and narrow, subtriangular, proximal width ½ length, rounded distal margin has 3 fine setae. Basos slender, margins parallel, width about 1/7 length, a few fine setae on anterior margin. Ischium about 1/7 basos length, barely longer than wide, rounded lobe-flange anterodistally. Merus as wide as basos, ½ its length, anterior margin only slightly convex and constricted proximally, a few very minute setae on posterior margin. Carpus slightly narrower and shorter, fine spine-setae posterodistally, a few minute setae posteriorly. Propod linear, ½ as long again as carpus, narrow, 14 slender spines on posterior margin; slightly curved short slender dactylos less

than ⅓ propod length. Second: Sideplate subrectangular, angles rounded, posteriorly excavate so width of proximal portion ½ length, of distal ⅔ length; fine setae ventrally; otherwise like Pr. 1. Third: Sideplate barely wider than deep, depth barely more than ½ basos length, posterior lobe subsquare, a small slightly produced posterodistal angle Basos ovate, rectangular, width more than ⅔ length, posteriorly flanged, 9 small stout spines along anterior margin, 2 or 3 spine-setae on angle, posterior margin has about 16 serrations, each with quite fine long setae. Ischium subrectangular, barely longer than wide, width about ⅕ basos, 2 or 3 spine-setae anterodistally. Merus width about ¼ length, length ¾ basos, about 6 paired slender spines on anterior of subparallel margins, 5 single spines on posterior, 2 or 3 on each distal angle. Carpus linear, narrower, little more than ½ basos length, 4 or 5 sets of long fine setae on anterior surface, a few spines on distal angles. Propod narrower, almost as long as merus, short transverse rows of long fine setae form continuous tract down one margin, single row of 10 or so spines down opposite; very short spike-like dactylos. Fourth: Sideplate small, subrectangular, wider than deep. Longer than Pr. 3, about 15 spines down posterior margin of propod, otherwise much the same. Fifth: Much the longest, sideplate small and ovate. Fewer spines and serrations on basos than in Pr. 3, carpus has 3 groups of spines on anterior margin, spines on distal angles; 4 groups of 2 or 3 fine setae and a spine-seta on posterior; propod margin has about 12 pairs of spines; other margin has an equal number of rows of spine-setae and setae; dactylos a long slender spike about ⅓ propod length.

Epimeral Plates. First ovately subtriangular, with ventral angle slightly produced; 2nd and 3rd subrectangular with anterodistal angle rounded, posterodistal slightly produced backwards; 2nd deeper than wide, 3rd wider than deep.

Pleopods. Normal, rami longer than peduncles, of about 15 or so plumose segments; 2 coupling spines on peduncle, inner ramus the longer.

Uropods. Tips reaching same distance. First: Inner ramus slightly the longer, a little more than ⅔ peduncle length; peduncle has stout spine on each superodistal angle, 1 or 2 spines and 2 or 3 long spine-setae on outer dorsal margin. Small spine and several minute setae on dorsal margin of inner ramus, up to 7 and 9 small spines on each dorsal margin of canoe-shaped outer ramus; integral end spine on each ramus. Second: Inner ramus as long as peduncle, outer slightly shorter, 2 stout spines on inner distal angle, 1 on outer; rami have 5 and 7 (outer) and 4 and 7 (inner) spines on dorsal margins; integral end spines. Third: Inner ramus barely longer than the outer; peduncle about ⅔ length inner, 2 spines on inner superodistal angle, 1 on outer, 1 on inferodistal angle; rami lanceolate, the narrower outer has 4 spines on outer margin; inner has 3 on outer margin, 5 on inner, minute terminal seta on prolonged tips of rami. Telson: Cleft almost to base, narrow lobes each about 4 times as long as wide, end acute with quite deep notch just outside and below tip, long strong spine in notch, 1 or 2 minute setae inside spine, sharp tooth outside.
