broad denticiilate cutting edge and accessory plate, spine-row of 2 spiues, 

 palp densely setose; right witli cutting edge of 4 strong teeth, no accessory 

 plate, 2 spines in spine-row. Maxiila 1, inner plate small, with 1 seta, 

 outer with 7(8?) — 10 spines, 1 setiforin, the rest smooth or with 1 tooth 

 near the base, 2*^ Joint of palp distally greatly expanded, with many spine- 

 teeth. Maxilla 2, inner plate rather the broader, both slender. Maxillipeds 

 (Fig. 59), inner plates rudimentary, outer broad, densely fringed, springing 

 from a large base, finger of palp small. Gnathopods 1 and 2 (Fig. 57) not 

 large, simple, ö^^^ Joint subfusiforai, long, 6^^^ small, spinöse, finger beset 

 with spines or spinules. Peraeopods 1 and 2, 4*^ and ö^'i joints laminar, spinöse, 

 5*'^ the longer. Peraeopods 3 — 5 long, finger short. Uropods 1 and 2 spinöse, 

 rami subequal, uropod 3 projeeting, rami subequal, foliaceous. Telson deeply 

 cleft, armed with marginal spines, apices divergent.
