Body fusiform. Hooded rostrum covering base of antenna, lateral corners 

 of head obsolete, postero-antennal angles distinct. Side-plates rather large, 

 Xst_4th obtusely truncate, hinder lobe of side-plate 5 the deeper. Pleon segments 

 4 — 6 in ö nariower than in 9 . Eyes dorsal, lateral or wanting. Antennae 

 more or less modified in d, short in 9, accessory flagella well developed. 

 Epistome not projecting. Upper lip rounded. Inner lobes of lower lip usually 

 small. Mandible short, cutting edges distinctly developed, molar variable, 

 seldom large, palp rather large. Maxiila 1, inner plate small, palp 1- or 

 2-jointed. Maxiila 2, plates short, rounded at apex. Maxillipeds, plates small, 

 palp large. Gnathopods 1 and 2 generally similar in form, hands subchelate, 

 large, with palmar tooth fortified by a spine. Peraeopod 4 the longest. 

 Peraeopod 5 (Fig. 37, 38) short, 2'^ Joint greatly expanded. Branchial vesicles 

 simple. Pleopods stronger in d than in 9 . üropod 3 often varying sexually, 

 outer ramus the longer. 2-jointed. Teison cleft to or nearly to the base.
