distally, ciliated at tip. Eyes placed widely apart on sides of cepha- 

 lon. Superior antennae very small, with subfusiform flagellnm. 

 and formed of numerous very short articulations clothed with 

 delicate sensory filaments. Inferior antenn?e with slender 

 elongated flagellum. Epistomal plate very narrow. Anterior 

 and posterior lips normally developed. Mandibles very strong, 

 cutting-edge divided into limited number of coarse teeth, and in- 

 side a distinct denticulated secondary lamella, narrow ensiform 

 molar expansion with regular series of small denticles along an- 

 terior edge, and palp not very large. Anterior maxillae with mas- 

 ticatory lobe very large and broad, coarsely spinous at tip, basal 

 lobe small, carries three densely plumose setae. Posterior max- 

 illae ends in two narrow setiferous lobes, and inside short densely 

 setous masticatory expansion. Maxillipeds with quite short basal 

 part, epignath linguiform, points outwards, small masticatory 

 lobe distinct with two curved hooks inside, fine articulate palp 

 large, joints complicated and densely setous. Legs with more or 

 less expanded joints, edged with spines and bristles, dactylus 

 comparatively short and not hook-shaped. Three anterior pairs 

 of legs much shorter than posterior, turned forwards. First pair 

 of pleopoda not differing much from others. Uropoda with basal 

 part produced inside, outer plate narrower than inner.
