 setae, outer with 10 (V) spines. palp 2-jointed, not reacbiug- extremity of 

 outer plate. Maxilla 2, outer plate the longer, ratlier tlie narrower, obliquely 

 truncate, inner still more so and fringed for half its length. Maxillipeds,

Peraeon broad, smooth, 7^^ segment and pleon segments 1 and 2 dorsally 

 produced into 2 teeth. Rostrum nearly reaching apex of 1^* Joint of antenna 1. 

 Side-plates 5 and 6, hind lobes rounded. Pleon segments 2 and 3, postero-lateral 

 Corners acute, scarcely produced. Eyes long, narrow, curved, pale reddish. 

 Antenna 1, 1^* Joint longer than 2^ and 3*^ combined, with an apical tooth, 2*^ with 

 2 apical teeth, flagellum with 22 rather long joints, many with sensory filaments, 

 ist JQJjjt longest. Antenna 2 shorter, ultimate Joint of peduncle rather shorter 

 than penultimate, flagellum with 44 joints, all short except l***. Upper lip slightly 

 narrowing to insinuate apex. Mandible, apical tooth obscurely subdivided, 

 to the rear a 2*^ tooth probably representing the accessory plate, but apparently 

 not free, molar a thin expausion slightly fringed with minute spinules, 3*^ Joint 

 of palp Short, scarcely longer than 1^*; its blunt apex obliquely truncate, 

 slightly fringed, 2*^ Joint little longer than 3^. Maxilla 1, inner plate with 

 9 setae on oblique distal margin, outer with 10 spines, palp not rudimentary, 

 but not reaching end of outer plate. Triturating lobes of stomach very 

 small, with minute spiue-teeth. Gnathopod 1, 5^^ Joint tapering, much longer 

 than 6*^, otherwise as in Iphimedia (p. 214), with small finger opposed to 

 very slender thumb. Gnathopod 2 rather stouter, 5*^ Joint shorter than 6^''. 

 which widens a little distally and forms a little distinct chela with the small 

 finger. Peraeopods 3 — 5, 2^ Joint strongiy expanded, rounded oval, hind 

 margin strongiy serrate. Uropod 2, rami very unequal, uropod 3, peduncle 

 with acute points, rami only a little unequal. Telson longer than broad. 

 slightly tapering, apex widely not deeply emarginate. Marsupial plates large 

 and long. Colour varying fi'om light to dark brown, thickly covered with 

 black stellate markings. L. 11 mm.
