mouth parts. Upper Lip: Finely setose dis- 
tally. Lower Lip: Inner lobes vestigial; inner 
and end margins of principal lobes strongly 
bristled. First Maxillae: Inner plate the shorter. 
Palp minute with only barest suggestion of a 
2nd segment. Second Maxillae: Plates sub- 
equal, distally setose. Left Mandible: Molar 
process has large setulose spine on inner 
proximal margin; spine-row of 4 setose spines; 
cutting edge of 3 plates, upper with 3 teeth, 
lower of 4, median of 2. Right Mandible: 
Cutting edge, upper plate of 4 teeth, accessory 
U-shaped, upper edge of U fimbriated and 
lower with 4 or 5 teeth. Maxilliped: Dactylos 
rudimentary. Inner and outer plates well- 
developed, inner with 3 stout teeth on end, 
a spine between each tooth, 2 pairs of plumose 
setae down cleft. Outer plate reaching Vi along 
carpus, distally sickle-shaped and prolonged 
to fine tip tufted with setae, convex outer 
margin naked; 4 sets of 1 or 2 spines on inner 
margin, a pair on outer surface at merus level. 
Carpus as long as propod, merus shorter and 
wider, 2 or 3 long spines on outer distal angle 
of each; groups of fine setae on inner distal 
angles; inner surface of merus and carpus 
shallowly concave; small dome-like and seta- 
tipped dactylos ringed by 5 or 6 spines on end 
of propod. 
gnathopods. First: Sideplate ovate-rectan- 
gular, ventrally and posteriorly spined. Basos 
width !4 length, a few small spines anteriorly, 
2 or 3 large stout spines posteriorly and at 
distal angle. Ischium subsquare, as wide, 
spined posterodistally. Merus subtriangular, 
a little longer than ischium, small scabrous 
pellucid lobe and 4 or 5 spines on posterior 
margin; anterior contiguous with proximal 
half of carpus posterior margin. Carpus sub- 
triangular, almost twice size of merus, spined 
anteriorly and posteriorly; posterodistally ex- 
panded into slightly scabrous and pellucid 
lobe; row of about 6 spines obliquely across 
posterodistal surface. Propod slightly shorter 
and narrower than carpus, narrowing further 
to long curved dactylos; 3 sets of 2 or 3 
spines on anterior margin, posterior and end 
margins strongly spined. Dactylos Vi propod 
length, has spine on inner margin. Second: 
Sideplate subsquare, ventrally and posteriorly 
spined, posteriorly excavate. Basos width 
about !4 length, anterior margin and postero- 
distal angle spined. Ischium subrectangular, 
width Vi length, posterodistally spined. Merus 
subrectangular, as long and wide as ischium, 
posterodistally produced to scabrous pellucid 
lobe, with 1 or 2 spines either side. Carpus 
wider, about twice as long, anteriorly convex, 
1 or 2 spines on distal angle; posterior margin 
expanded to scabrous pellucid lobe, about 
5 long spines along lobe base. Propod longer 
and narrower, with scabrous pellucid poster- 
ior margin produced in distal lobe beyond end 
of dactylos; 1 or 2 spines on anterior margin, 
2 or 3 on anterodistal angle, a double row of 
spines medially along surface. Dactylos small, 
palm slightly oblique, pair of spines at inner 
base of dactylos and dactylos tip. 
peraeopods. First: Sideplate subrectangu- 
lar, posteriorly excavate, ventrally and pos- 
teriorly spined. Basos width about Vs length, 
margins spined. Ischium subsquare, postero- 
distally spined. Merus as wide, about 3 times 
as long, a few spines anteriorly, quite strongly 
spined posteriorly. Carpus about Vs merus 
length, narrower, similarly spined. Propod 
longer, narrower, similarly spined. Short 
curved dactylos has spine on inner margin. 
Second: Segments shorter and narrower than in 
Pr. 1; otherwise similar. Third: Anterior lobe 
of sideplate larger than posterior; small spines 
ventrally and posteriorly on each margin. 
Basos ovate, narrowing distally, margins 
spined, those on anterior margin the stronger; 
other segments stouter than in Pr. 1, propod 
and dactylos longer, spines stouter. Fourth: 
Longer than Pr. 3. Basos further expanded, 
segments comparatively longer than in Pr. 
3, otherwise similar. Fifth: Much the longest; 
basos nearly as broad as long, posterior mar- 
gin finely serrate and minutely spined.
