 produced. Side-plate 1 produced forward; side-plate 4 neither ex- 

 cavate nor serrate behind ; side-plates 5 and 6 with back ward turning 

 projections near lower bind corners. Pleon segment 3 with the 

 postero-lateral corners acntely produced, and faintly serrate above. 

 Antenna 1, first and second joints of the pediincle long and subequal 

 the third shorter; flagellum 23— 24-jointed; accessory flagellnm 

 10-jointed. Antenna II shorter than 1, peduncle elongate, the penul-

 symmetrically rounded. Lower lip with the inner lobes not developed. 

 Mandible with molar smail; about six sraall spines in spine-row; 

 cutting plates small, weakly dentate; palp three-jointed, the second 

 Joint slightly the longer and wider. Maxilla 1, inner plate with 

 four apical setae; outer plate with nine toothed spines; second Joint 

 of palp tipped with setae. Maxilla 2, outer plate both broader and 

 longer than inner, both apically fringed, the inner slightly fringed 

 on the inner margin. Maxillipeds, inner plate rectangular; broadly 

 curved; palp 4-jointed. 



Gnathopod 1 slender, the fifth Joint produced, incurved on the 

 front margin, longer than the sixth ; the sixth similar to gnathopod 2, 

 but much smaller; the palm convex, with sniall spines. Gnathopod 2 

 of the female with the fourth Joint produced into an acute process 

 behind; the fifth Joint rather broad; the band broad, palm oblique, 

 serrate and spinöse, with the usual two spines at the apex, finger 

 strong Avith slender setules on the outer side. Gnathopod 2 of the

 spinöse, serrate, one excavation between hinge and middle of tooth, 

 and one wide excavation between the middle and the apex, with 

 one to three small teeth in the middle of the excavation. Pereio- 

 pods 1 and 2 slender, the second Joint curved, and the finger narrowed 

 and toothed. Pereiopods 3—5 slender, the second Joint somewhat
