Body rather stout. Hood not carinate or deflexed. Side-plates 1 — 4 

 with several simple setae on lower margin, 4*'' rather broad, 5^^ with bind lobe 

 rounded. Eyes well developed. Antennae 1 and 2 in Q nearly equal, antenna 2 

 in ö, flagellum of moderate length, slender, calceoliferous. Mandible, cutting 

 edges and spine-row well developed, molar feeble, tipped with spinules, 

 palp narrow with few setae. Maxilla 1, palp 1-jointed, well developed. 

 Maxilla 2, inner plate smaller than outer. Maxillipeds, inner plates obtusely 

 rounded at apex, 3*^ Joint of palp not produced, 4*^ slender, curved. Gnatho- 

 pods 1 and 2 alike in structure. Peraeopods 1 — 5 about as in Phoxocephalus
