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 spinulo on 

 either side a little beyond the centre. 



First antenna stout, 1st joint a little longer than broad, 2nd and 

 3rd subequal, lower margin with long setae, flagelluin a trine longer 

 than 3rd peduncular joint, 4-jointed, 1st joint equal to all the rest 

 together, accessory flagellum small but distinct, 1-joiuted. 



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, maudibular 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 1st maxilla and 2nd maxilla not successfully 

 dissected out. 



First guathopod 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 ? similar. 



Second gnathopod in , 2nd joint long, uai'row, curved forwards 

 (similar to that of Ischyrocerus carinati/g), 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 half as long as 6th joint,
