ovate in outline, though fused to each other 

 mesially, and each with a short upturned spine on 

 anterior surface. 



Antennular peduncle (Fig. 3a, 6, c) reaching 

 beyond end of antennal scale; basal article 1.1 as 

 long as second and about 2.5 as long as third, all 

 measured on ventral margin; stylocerite well sep- 

 arated from peduncle, tapering to slender elon- 

 gate tip reaching tip of distolateral spine on basal 

 article; latter exceeding distodorsal margin of ar- 

 ticle, fringed by transverse subdistal row of setae, 

 and closely appressed to second article, distome- 

 sial spine much smaller; shorter second article 

 with stronger mesiodistal spine. Dorsolateral 

 flagellum about length of carapace, thickened in 

 basal 2/3, with annulations, except at base, longer 

 in female than in male and much longer than in 

 whiplike distal part; ventromesial flagellum 

 somewhat shorter and with annulations of vari- 

 able but shorter length. 



Antennal scale (Fig. 3a, 6) about twice as long 

 as wide, distolateral tooth strong, falling slightly 

 short of broadly rounded distal margin of blade; 

 basal article with acute distal spine ventrally; 

 flagellum (broken in material studied) probably 

 slightly exceeding length of body. 



Mandibles (Fig. 4a) similar, with 2-segmented 

 palp, incisor process broad and armed with 8 mar- 

 ginal teeth, slender molar process simple, diver- 

 gent, its narrowly rounded tip minutely setose. 



First maxilla (Fig. 46) with proximal endite 

 asymmetrically oval-triangular, distal margin 

 bearing many long setae; distal endite with nar- 

 rowed base but broadened distally, armed with 

 many (about 30) short spines on mesial margin 

 and with scattered longer spinules submarginally 

 and marginally beyond either end of spine row; 

 palp scarcely bifurcated, with long distal spine on 

 obsolescent proximomesial branch and 1 shorter 

 submarginal spine on distal branch. 



Second maxilla (Fig. 4c, c?) with proximal en- 

 dite represented by 2 similar lobes; distal endite 

 subtriangular, expanded mesiodistally and paral- 

 leled laterally by narrow, somewhat twisted palp; 

 scaphognathite with anterior lobe rectangulo- 

 ovate, fringed with uniformly long, silky setae on 

 anterior and mesial borders, uniformly shorter 

 setae along entire lateral margin; posterior lobe 

 narrow and acuminate, fringed on blunt tip and 

 adjacent mesial margin by strikingly long, 

 strong, tangled setae preceded proximally by 

 shorter setae similar to those on lateral margin. 



First maxilliped (Fig. 4e, f) with irregularly 

 fusiform endite, short palp concealed and much 



exceeded in length and size by leaflike exopod, 

 epipod obscurely bilobed; indistinct mesial lobule 

 on exopod possibly representing incipient lash. 



Second maxilliped (Fig. 4g, h) somewhat pedi- 

 form but flattened, mesial margin of articles 

 bearing long, feathered setae, mesial surface of 

 terminal article densely setose, exopod barely ex- 

 ceeding leaflike epipod. 



Third maxilliped (Fig. 4i, j) slender, 5- 

 segmented, reaching beyond antennular pedun- 

 cle; terminal article trigonal in cross section, ta- 

 pered distally, bearing 3 spines, transverse tracts 

 of dense setae along mesial surface; similar tract 

 of setae on carpus and another conspicuous group 

 mesiodistally on merus-ischium, latter with stout 

 distolateral spine at articulation with carpus; 

 exopod much reduced, subtriangular, without 

 lash. 



First pereopods (Figs. 3^, k; If-k) chelate, 

 subequal and sexually dimorphic, at least in fully 

 mature individuals; fingers curved ventrally and 

 slightly laterad; dactyl more slender than and 

 with level of tip slightly shorter than or equal to 

 that of fixed finger; mesial surface of each finger 

 convex, lateral surface concave, with opposed sur- 

 faces uniformly offset; closing without gape, each 

 armed on prehensile edge with row of almost uni- 

 form teeth so closely set as to be almost contigu- 

 ous, acute tip of dactyl slightly spooned by elon- 

 gate teeth slanted distad and curving around its 

 external edge; line of sensory hairs mesial to cut- 

 ting edges. Leg shorter than to almost equaling 

 third maxilliped. Palm of holotype male inflated 

 laterally, but apparently somewhat irregularly 

 concave mesially, length 1.4 greatest height and 

 longer than fingers; palm relatively shorter in 

 allotype female, 0.3 length of fingers. Carpus 

 shorter than palm, with oblique ventral crest end- 

 ing in strong distolateral spine, flanked mesially 

 by patch of setae on polygonal raised area. Merus 

 somewhat swollen in distal half, distinct from is- 

 chium but fused to it, neither armed. 



Second pereopod (Figs. 3/ ; 7e ) shorter and more 

 slender than first, reaching about to end of anten- 

 nal peduncle; fingers slightly longer than palm, 

 similar in size and shape, opposed edges without 

 gape, each pectinate with single row of teeth in 

 distal half directed obliquely distad and increas- 

 ing slightly in size to end in noticeably stronger 

 tooth crossing opposite member when closed, but 

 spineless proximally; carpus slender, about 1.16 

 longer than chela; merus and ischium unarmed. 



Third to fifth pereopods (Fig. 3m, n,o) similar 

 in length and structure, third reaching to tip of or
