General form like Amphilochus (p. 149). Upper lip distally wider, less 

 deeply incised. Lower lip with lobes more strongly inflexed. Mandible, 

 molar obsolete, palp longer, 3"^ Joint elongate. Maxilla 1, inner plate very 

 small, outer with dentate expansion below the apical spines, palp broad, 

 2-jointed. Maxilla 2, plates very small, almost unarmed. Maxillipeds, plates 

 moderately broad, not elongate, palp long. Gnathopods 1 and 2 similar, 

 2^ much the larger, with setiferous process of 5*^ Joint more produced, 

 6*^ Joint almost fusiform, palm being very oblique, finger long with nodiform 

 denticle in one or both of the pairs on inner margin near hinge. 



3 species.

Head, rostrum large, much defiexed, lateral corners nearly rectangular. 

 Side-plate 1 obliquely quadrate, lower front angle acute, 2^ slightly denticulate. 

 Pleon Segment 3, postero-lateral angles produced to a distinct acute tooth. 

 Eyes large, rounded oval, dark red. Antenna 1, 2^ Joint produced on inner 

 side to acute apical process, flagellum much shorter than peduncle, about 

 7-jointed, carrying setae. Antenna 2 rather longer than antenna 1, ultimate 

 Joint of peduncle much shorter than penultimate, flageUum much shorter than 

 peduncle, 7-jointed. Gnathopod I, process of 5*^*^ Joint not reaching palm, 

 6*^^ Joint twice as long as broad, palm denticulate, as long as bind margin, 

 finger with nodiform denticle, tip much overlapping the palm. Gnathopod 2,
