The mouthparts are of the usual type, the maxilliped (Text-fig. 24c) is broad, with the basipodite separated from its lamella by a suture; the maxilla (Text-fig. 24rf) has its two outer lobes each bearing two long setae with delicate pectinations along their inner edges; the truncate distal end of the fixed lobe is fringed with delicate setae; the outer lobe of the maxillula (Text-fig. 24e) is stout and bears ten Text-fig. 25.

The first, second, sixth and last pereiopods are shown in Text-figs. 25 a, b, c and d. The propodus of the first is greatly expanded, with its inner edge armed with a row of about twenty-two broad processes alternating with modified spines (Text-fig. 25/); the dactylus bears five flattened spines in its distal region and the distal end of the carpus is crenulate and bears two modified spines similar to those on the propodus. The second pereiopod (Text-fig. 256) is much smaller than the first, with the propodus expanded and its inner margin armed with stout spines, a pair of which occurs at about the middle of its length and a group of four at its broadened proximal end. The remaining pereiopods.
