molar bearing a very short minutely setulate distal 
seta. Maxillae (Figure 1). Right and left palps of first

sub-apical spines on the left. The outer plate 
bearing 6 denticulate apical spines and a single 
slender 7th medio-distal spine on the left, the right 
outer plate bearing 7 denticulate or barely 
denticulate apical spines and a single moderate, 
naked, medial, sub-apical spine. Inner plate with 
12 (right) or 13 (left) medial plumose setae. Second 
maxilla, both plates with outer apical margin 
pubescent. Inner plate with baso-medial 
pubescence extending across the face basal and 
distal to an oblique row of setae forming a sub- 
apical pubescent crescent. The outer plate with few 
medial and several apico-medial setae. Maxilliped

(78:52), the comer of the left palm marked with \ 
lateral and 1 medial strong bifid spine and a singly 
moderate lateral seta, the right palm marked 
laterally and medially with 2 strong spines and \ 
long lateral seta. Palm slightly convex posteriorly, 
excavate anteriorly, with fine marginal cusps, lef( 
palm slightly oblique. Dactyl almost reaching th«\ 
palmar comer, the right more slender than the lef( 
with 4 accessory spinules, sub-marginal on th(\ 
lateral face, and a single dorsal spine at M0.2, the* 
left with 3 facial spinules, and a 4th distal spirit 
almost as an accessory tooth, and both lateral and 
medial sub-dorsal spines at M0.25 and 0.20 . Left 
dactyl bearing distal nail, absent on right. Second 
gnathopod (Figure 2) dactyl without nail, bearing 3 
inner accessory spines at M0.65-0.75, and a singly 
small seta sub-marginal on the medial face at M0.4. 
Palm with 3 lateral and 3 medial stout trigger 
spines as well as 2 strong medial trigger spines and 
2 long apically curved spines defining the palmat- 
corner. Palmar length sub-equal to the fre^ 
posterior length of the article. Free margin and 
corner of palm bearing long 'Hadziid' spines. 
Coxal plate broader than of Gl, but still longer
