 piriform, 4**», o^^ and 6^^ subequal. üropod 3, rami narrow, longer than 

 peduncle. Telson decidedly longer than broad, quadrangular, apically truncate, 

 armed with spinules. Colour whitish, tinged with yellow. L. 9 6 mm.

Rather slender, but tumid anteriorly. Frontal process rather large, strongly 

 arched distally, but the small rostral apex projected horizontally. Side-plate 1 

 much expanded and produced forward, 5*^ nearly as deep as 4^^'. Eyes of moderate 

 size, oval, light red, at distal end of frontal process. Antenna 1 in 9 

 little longer than peduncle of antenna 2, 2*^ Joint rather longer than 1^*, flagellum 

 as long as 2*^ and 3^ combined, 10-jointed. Antenna 1 in d, 1^* and 2^ joints 

 equal, flagellum longer than peduncle, with 14 joints, first 10 thickened, hirsute. 

 Antenna 2 in o , ultimate Joint of peduncle longer than penultiraate, both densely 

 setose, together longer than flagellum. Antenna 2 in d, peduncle nearly bare, 

 flagellum very long, filiform. Guathopod 1 rather feeble, process of 5*^ Joint 

 broadly rounded and setose, 6*** Joint subequal to 5*^ oblong oval, palm ill- 

 defined, nearly twice as long as bind margin. Gnathopod 2 similar to gnatho- 

 pod ], but longer and more slender. Peraeopods 1 — 4 densely setose, the 

 finger about as long as 6*^1 joiiit, the latter in peraeopods 1 and 2 subfusiform, 

 with dense tuffcs on distal half of fi-ont margin. Peraeopod 5, 2*^ Joint 

 rounded oval, 4*^ and 5*^ equal, 6*^ rather longer than either. üropod 3, 

 rami spinulose, narrowly lanceolate, longer than peduncle. Telson oval, apex 

 broadly rounded. carrying several setules. Colour pellucid whitish. lightly 

 tinged with red; ova orange-coloured. L. 8 mm.

Very tumid anteriorly. Frontal process broad, strongly arched, the small 

 rostral apex jutting out nearly to end of 1^* Joint of antenna 1. Side-plate 1 a 

 little expanded distally, 5*^ decidedly less deep than 4*^. Eyes unusually large, 

 rounded, prominent, dark red, occupying most of frontal process. Antenna 1 

 in 9 Short, little longer than peduncle of antenna 2, 1^* Joint as long as 2^ and 

 3^ combined. flagellum shorter than peduncle, 5-jointed. Antenna 2, ultimate 

 and penultimate joints of peduncle subequal, flagellum nearly aslong as peduncle.
