FISHERY BULLETIN: VOL. 86, NO. 2 



separated from peduncle, tapering to slender 

 elongate tip reaching about 1/4 length of second 

 article, basal article with distodorsal margin 

 flanked by transverse row of setae, extended into 

 strong lateral spine reaching level equal to that of 

 stylocerite and closely appressed to second article; 

 shorter second article with strong mesiodistal ap- 

 pressed spine. Dorsolateral flagellum about 1.5 

 length of carapace, thickened proximal half bear- 

 ing conspicuous ventral setae; ventromesial flag- 

 ellum somewhat more slender in lateral view and 

 shorter. 



Antennal scale (Fig. la, 6) about 2.5 as long as 

 wide, distolateral tooth falling short of distome- 

 sial apex of broadly rounded distal margin of 

 blade; basal article with strong ventrolateral 

 spine; flagellum slightly exceeding length of body 

 (missing from holotype). 



Mandibles (Fig. 2g) similar, with 2-segmented 

 palp, incisor process broad and armed with 8 

 marginal teeth, slender molar process simple, 

 divergent, its narrowly rounded tip minutely 

 setose. 



First maxilla (Fig. 2h) 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 37) short spines on mesial margin 

 and with scattered longer spinules marginally 

 and submarginally 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. 2i) with proximal endite 

 represented by 2 similar lobes; distal endite sub- 

 triangular, 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, shorter setae along 

 entire lateral margin; posterior lobe narrowly 

 ovate-triangular, fringed on blunt tip and adja- 

 cent mesial margin by strikingly long, tangled, 

 strong setae preceded proximally by shorter setae 

 similar to those on lateral margin. 



First maxilliped (Fig. 2j, partly flattened view) 

 with irregularly fusiform endite, short palp much 

 exceeded in length and size by leaflike exopod, 

 epipod obscurely bilobed. 



Second maxilliped (Fig. 2k, I) somewhat pedi- 

 form but flattened, mesial margin of articles 

 bearing long, feathered setae, mesial surface of 

 terminal article densely setose, tip of exopod ex- 

 ceeding leaflike epipod. 



Third maxilliped (Fig. 2m, n) slender, 5- 

 segmented, reaching beyond antennular pedun- 

 cle; terminal segment trigonal in cross section, 

 tapered distally, bearing 3 terminal spines, 

 oblique tracts of dense setae along mesial surface; 

 similar tract of setae on carpus and another less 

 conspicuous group on merus-ischium, latter with 

 distolateral spine at articulation with carpus; ex- 

 opod much reduced, ovate-triangular, without 

 lash. 



First pereopods (Fig. le, f) chelate, subequal; 

 fingers curved ventrally and slightly laterad; 

 dactyl much more slender than and slightly 

 longer than fixed finger; mesial surface of each 

 finger convex, lateral surface deeply concave; pre- 

 hensile surfaces uniformly offset, closing without 

 gape, each armed with row of almost uniform 

 teeth so closely set as to be almost contiguous, 

 line of sensory hairs mesial to cutting edges, 

 acute tip of dactyl slightly spooned by elongate 

 teeth slanted distad and curving around its exter- 

 nal edge. Leg not reaching tip of third maxilliped 

 and exceeding antennal peduncle. Palm of holo- 

 type female inflated, length slightly greater than 

 height and shorter than fingers (0.60); low ridge 

 ending in small hooked spine on proximomesial 

 surface near articulation with carpus. Carpus 

 longer than palm; bearing oblique ventral crest 

 ending in strong distoventral spine and flanked 

 mesially by patch of setae on triangular raised 

 area; rectangular distal notch above spine fol- 

 lowed by oblique distomesial margin leading to 

 poorly defined spine at condyle articulating with 

 palm; distolateral margin with rounded ventral 

 corner leading to sinuous border above it bearing 

 2 lobes near articulation with palm. Merus some- 

 what swollen is distal half and bearing small dis- 

 tomesial spine, distinct from ischium but fused to 

 it. 



Second pereopod (Figs. 1^, h; 11) shorter and 

 more slender than first, but reaching beyond an- 

 tennal peduncle by about length of fingers. Fin- 

 gers slightly shorter than palm, similar in size 

 and shape; opposed edges without gape, each 

 spineless proximally, but distal half pectinate 

 with single row of spines directed obliquely distad 

 and increasing slightly in size to end in notice- 

 ably stronger spine crossing opposite member 

 when closed. Carpus slender, about 0.9 length of 

 chela; merus and ischium unarmed. 



Third to fifth pereopods (Fig. 2a-f) similar in 

 length and structure, third reaching distal edge of 

 antennal scale. Length articles of these legs in 

 holotype 9, mm:
