Gnathopods. First: Basos expanded, ovate, margins convex; greatest width ½ length, 2 or 3 spines on posterodistal angle. Ischium less than ¼ basos length, subsquare, 3 or 4 spines on posterodistal angle. Merus anterior margin short, posterior and end margins subequal, less than ⅓ basos length; posterodistal angle acute, produced somewhat outwards, end margin strongly spined. Carpus ⅖ basos length, widening somewhat distally to ⅔ length; posterodistal angle acute, produced downwards a little about ⅓ along propod, 1 or 2 small spines on anterior margin; posterior and end margins strongly spined, several short spines on posterior surface, end margin finely bristled between spines. Propod anterior margin ⅓ basos length, width less than anterior margin, which is slightly convex, has 3 or 4 strong spines; strong spines on surface; posterior margin finely toothed. Dactylos slender, more than ½ propod length; posterior margin finely toothed. Second: Basos ovate, strongly expanded, greatest width ½ length, posterodistal angle spined. Ischium not quite ¼ basos length, posterodistal angle spined. Merus anterior margin short, posterior as long as end, slightly more than ¼ basos length, end margin strongly spined. Carpus expanded distally by forwardly produced posterodistal angle, which extends ½ down propod; anterior margin slightly shorter than posterior, which is nearly ½ basos length; end margin strongly spined, several spines on posterodistal surface. Propod ⅓ basos length, a few spines on anterior margin and surface, slender, posterior margin finely toothed. Dactylos slender, ½ propod length, posterior margin finely toothed.

Pehaeopods. First: Gill large, subtriangular. Basos greatest width ⅖ length, margins convex, posterior with several short stout spines, posterodistal angle spined. Ischium subrectangular, less than ¼ basos length. Merus almost linear, width slightly more than ½ length, length ¼ basos. Carpus width ⅖ length, length nearly ⅖ basos, linear, posterior margin has 2 small spines. Propod width about 1/7 length, narrowing to slender dactylos, length ½ basos, surface minutely toothed, posterior margin with comb of fine teeth. Dactylos about ¼ propod length. Second: Basos proportionately narrower, propod posterior margin without comb. Third: Very similar, but reverted, proportions different; basos has two posterior margins, a flange effect, one flange widening distally and the other proximally, giving crossed appearance. Basos greatest width ⅔ length, ischium ¼ basos length. Merus linear, ⅓ basos, width more than ½ length. Carpus linear, width ⅓ length, length nearly ½ basos. Propod about 1/7 basos length, width about ⅙ length, no sign of spines on any segment. Fourth and Fifth: Segments wider, posterior margin of basos flanged, but flanges not crossed; propod surface with area of minute teeth.

Epimeral Plates. Broadly rounded but with distinct and slightly produced posterodistal angle, posterior margin tending to concave distally immediately above angle, convex proximally, a strong median ridge running in convex are from posterodistal angle (which may be almost median in position).

Pleopods. Peduncle stout, longer than wide, rami slightly longer than peduncles.

Uropods. Rami of uropod 1 not reaching quite as far as rami of 3rd; inner ramus of 2nd reaching as far as outer ramus of 1st. Outer rami all lanceolate with outer margin smooth, almost straight; inner margin slightly convex and finely pectinate; inner ramus of 1st similar in shape but inner margin smooth, outer pectinate; inner ramus of 2nd and 3rd in shape more ovate, both margins pectinate; each distally produced to narrow finger. Inner margin of peduncle
