The eyes are dark^ with numerous cuuipoiieiits, the niargin^ 

 turned towards the side of the head nearly straight, that 

 towards the middle of the head being angularly convex. 



Tiie antennae arc normal^ the flageHum of tiie first pair com- 

 posed of eighteen joints_, tliat of the second stouter and a little 

 longer, with fourteen joints; in this pair the fifth joint of the 

 peduncle is a little longer than the fourth. 



• The epistome is much broader than long, the apex pointed. 

 The upper lip is rather deep^ with broadly rounded outer margin- 

 The mandibles have the characters usual in this genus, the 

 joints subequal. In the first maxillae eleven spines were counted 

 cutting edge undivided, the palp slight, with its first and second 

 on the outer plate, the inner having the usual foiu^ plumose setae. 

 In the plate of the maxilHpeds the greatest breadth is in the 

 upper half. 



The first gnathopods, like all the other limbs, have a spine out- 

 standing from the lower apex of the outer margin of the third, 

 joint- Owing to the channelling of this joint its outer apex seems 

 to lose its apical position. The fourth joint has five stout and 

 more or less plumose spines on the inner margin, the triangular 

 fifth has four and the sixth lias six. 



The second gnathopods arc considerably longer than the first, 

 and closely resemble the five pairs of peraeopods. all having the 

 fifth joint similar to the fourth but shorter, botli being spinose 

 along the inner margin and on the outer apex. The sixth joint 

 has spines along the inner margin- The bifid finger is stout. The 

 male organs on the seventh jietaeon -segment are elongate, taper- 

 ing.^ 



The pleopods have only three hooked spines on inner apex of 

 peduncle. The male appendage of the second pair is much longer 

 than the rami. In the fourth and fifth pairs the branchial ramus 

 is strongly plicated. The covering ramus in the fifth has a trans- 

 verse suture as in the third and fourth pairs- 



The uropods are broad, somewhait hirsute, the movable outer 

 ramus having a little notch at the apex of its outer margin, w-hicli 

 is often obscured by the setules ; it reaches a little beyond the 

 inner ramus and the telson.
