FISHERY BULLETIN: VOL. 86, NO. 2 



nearly uniform size, occasionally unequal in 

 number on either side; posterior margin convex, 

 armed with 2 principal spines at each corner and 

 8-12 feathered strong setae on distal margin be- 

 tween. 



Eyes (Fig. 5a, 6) with cornea imperfectly devel- 

 oped; unfaceted though diffusely pigmented in 

 adults, but with internal facetlike pattern in 

 smaller individuals; ovate in outline though fused 

 to each other mesially, and each with an up- 

 turned spine on anterodorsal surface. 



Antennular peduncle (Fig. 5a, b, c) reaching 

 beyond end of antennal scale; basal article 1.3 

 length of second and about 2.2 length of third, all 

 measured on dorsal margin; stylocerite well sepa- 

 rated from peduncle, tapering to slender elongate 

 tip variably reaching as far as midlength of sec- 

 ond article; basal article with distodorsal margin 

 exceeded by rostral tip though extended into 

 strong lateral spine reaching level equal to that of 

 stylocerite and closely appressed to second article, 

 much smaller distomesial spine slightly diver- 

 gent; shorter second article with stronger 

 mesiodistal spine. Dorsolateral flagellum about 

 twice length of carapace, thickened in basal half; 

 ventromesial flagellum somewhat shorter. 



Antennal scale (Fig. 5a, b) about twice as long 

 as wide, distolateral tooth strong, falling short of 

 broadly rounded distal margin of blade; basal ar- 

 ticle with small distal spine ventrally; flagellum 

 slightly exceeding length of body. 



Mandibles (Fig. 6a) similar, with 2-segmented 

 palp, incisor process broad and armed with 7 mar- 

 ginal teeth, slender molar process simple, diver- 

 gent, its narrowly rounded tip minutely setose. 



First maxilla (Fig. 66) with proximal endite 

 asymmetrically oval-triangular, distal margin 

 bearing about 25 long setae; distal endite with 

 narrowed base but broadened distally, armed 

 with many 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 ob- 

 solescent proximomesial branch and shorter adja- 

 cent submarginal spine and tangled setae on dis- 

 tal branch. 



Second maxilla (Fig. 6c) 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, uniformly shorter 

 setae along entire lateral margin, posterior lobe 



narrow and acuminate, fringed on blunt tip and 

 adjacent mesial margin by strikingly long, tan- 

 gled strong setae preceded proximally by shorter 

 setae similar to those on lateral margin. 



First maxilliped (Fig. 6d, e) 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. 6f, g ) 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. 6h, i, j) slender, 5- 

 segmented, reaching beyond antennular pedun- 

 cle; terminal article trigonal in cross section, 

 tapered distally, bearing 3 spines, transverse 

 tracts of dense setae along mesial surface; similar 

 tract of setae on carpus and another less conspic- 

 uous group on merus-ischium, latter with stout 

 distolateral spine at articulation with carpus; 

 exopod much reduced, subtriangular, without 

 lash. 



First pereopods (Figs. 5f, g; 7c, d) chelate, 

 subequal and sexually dimorphic, at least in fully 

 mature individuals; fingers curved ventrally and 

 slightly laterad; dactyl more slender than fixed 

 finger, tips varying slightly in relative length; 

 mesial surface of each finger convex, lateral sur- 

 face concave; prehensile surfaces uniformly off- 

 set, 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 elon- 

 gate teeth slanted distad and curving around ex- 

 ternal edge. Leg exceeding third maxilliped by 

 length of fingers in holotype male, but shorter 

 than third maxilliped in other individuals. Palm 

 inflated in holotype male, length 1.4 greatest 

 height and longer than fingers; palm relatively 

 shorter in allotype female and other individuals 

 examined, 0.3 length of fingers. Carpus shorter 

 than palm in holotype but longer than palm in 

 remainder of specimens examined, bearing 

 oblique ventral crest ending in strong distolateral 

 spine and flanked mesially by patch of setae on 

 polygonal raised area; notch above spine 

 smoothly concave and opposing low ridge ending 

 in small rounded spine on heel of palm; shallowly 

 concave anteromesial margin of carpus leading 

 dorsally to 2 low rounded lobes. Merus somewhat 

 swollen in distal half, distinct from ischium but 

 fused to it, neither armed.
