distinct, nearly round. Side-plate 1 small, 2-5 much deeper, about as 
deep as their segments, rounded-quadrate below, 6 not nearly as deep 
as 5, all the side-plates sloping outwards and giving the animal a rather 
broad appearance. 
Telson not quite as long as broad, semicircular, with a spinule on 
either side a little beyond the centre. 
First antenna stout, Ist jomt a little longer than broad, 2nd and 
3rd subequal, lower margin with long setae, flagellum a trifle longer 
than 3rd peduncular joint, 4-jointed, 1st joint equal to all the rest 
together, accessory flagellum small but distinct, 1-jointed. 
Second antenna stout and a little longer than 1st, ultimate joint 
longer than penultimate, flagellum a little longer than ultimate joint, 
4-jointed, 1st joint equal to all the rest together. 
Lower lip, inner lobes distinct, outer lobes entire, not divided, 
apically rounded, mandibular processes subacute. 
Mandibles, cutting-edge 3 (?) dentate, secondary cutting-edge in left 
bidentate, spine-row (in left) with three spines, molar somewhat 
conical, but apically blunt, palp large and stout, 2nd joint ovate, 
setose on inner margin, 3rd shorter than 2nd, laminar, expanded distal 
end with long setae. 
First maxilla, outer plate with 9 (?) spines, palp 2-jointed, 2nd joint 
long and very slightly widened distally. 
Maxilliped, outer plate reaching a little beyond middle of 2nd joint 
of palp, 2nd joint oblong, 3rd oval, half length of 2nd, 4th nearly as 
long as 3rd, narrow, bluntly pointed, both inner and outer plates and 
all the palpal joints setose. 
Upper lip, inner plate of Ist maxilla and 2nd maxilla not successfully 
dissected out. 
First gnathopod in ¢, 2nd joint narrow at base, distally widening, 
anterior margin produced into a rounded apical lobe with a few setae, 
3rd and 4th much narrower than 2nd, 5th shorter and slightly narrower 
than 6th which is oval, palm oblique, continuous with inferior margin 
but distinguished by 4-5 spines becoming smaller towards the hinge, 
finger matching palm, serrulate on inner apex, outer apex acutely 
produced over base of unguis, with a comb-like row of fine setules, 
unguis small; in 2 similar. 
Second gnathopod in @, 2nd joint long, narrow, curved forwards 
(similar to that of Ischyrocerus carinatus), whole of anterior margin 
serrulate, anterior apex not strongly lobed, 3rd slightly lobed, 5th very 
short but broad, inferior margin truncate, 6th large, elongate, oblong, 
palm plus inferior margin slightly concave, sparsely setose or with a 
fairly strong bifid tooth at the hinge, finger haif as long as 6th joint,
