Dorsal carina exteuding fi'om 2^ Joint of antenna 1 back to 4^^^ segment 

 of pleon. Head slightly rostrate, lateral aiigles produced to large slightly 

 deflexed linguiform lobes. Side-plates 4—6 carinate near the base, 5^'' 

 quadrate, not deeper than broad. Pleon segment 3, postero-lateral angles 

 quadrate, dorsal carina of this and of segment 4 acutely produced. Eyes oval, 

 larger in ö than in o , reddisb with opaque white coating. Antenna 1 in Q , 

 1^* Joint large, its dorsal carina jutting out over 2*^ Joint, which on a smaller 

 Scale is similar, flagellum short, with 7 joints, 1^* not large, accessoiy flagellum 

 wanting. Antenna 1 in d a little larger, 2^ Joint scarcely produced, flagellum 

 with 9 joints, 1*** very large (Fig. 12). Antenna 2 in Q shorter than antenna 1, 

 ultimate Joint of peduncle shorter than penultimate or antepenultimate, flagellum 

 4-jointed. Antenna 2 in d, ultimate Joint of peduncle as long as either of 

 2 preceding joints, flagellum as long as body. Epistome lai;ge, nearly rectangular. 

 Gnathopod 1, 6*^^ Joint shorter than 5*^ of nearly uniform width. Guathopod 2 

 very slender, 6*^ Joint more than half length of 5*^^, oblong triangulär. 

 Peraeopod 3, 2*^ Joint rounded, 4*^ expanded. Peraeopods 4 and 5, 2^ Joint oval, 

 uarrowed below, 4*^ expanded. üropod 3, rami very nearly equal (Fig. 13), 

 in g without setae. Telson naiTow and long, nearly 3 times as long as 

 broad, deeply cleft, apices closely adjacent, acute (Fig. 13). Colour chalky 

 white, with dorsal orange patch on each segment. L. § 7, c? 8 mm.

Dorsal carina extending from 1^* Joint, of antenna 1 to 4*^ pleon segment. 

 Head, lateral angles acutely produced. Side-plates large and deep, h^^ oval, 

 much deeper than broad, lower bind corner produced downward, the centre 

 formiug a conspicuous boss. Pleon segment 3, postero-lateral angles quadrate, 

 minutely produced, carinate process of this and segment 4 acutely upturned. 

 Eyes narrow oblong, red. Antenna 1, only P* Joint produced at apex, 

 flagellum in 9 with 8 joints, 1^* of moderate size, accessory flagellum 3-jointed, 

 very small. Antenna 2 in 9 nearly as long as antenna 1, flagellum 8-jointed. 

 Antenna of ö modifled as in L. longicome. Epistome obtusely rounded in 

 front. Gnathopod 1, 6*^1 joint about as long as 5*^ slightly widened distally. 

 Gnathopod 2, 5*^ joint considerably expanded distally, and 6*^ rather stouter 

 than in L. longicome. Peraeopods 3—5, 2*^ joint not narrowed below, 4**^ 

 not expanded. üropod 3, inner ramus notably shorier than outer; outer in 9 

 canying 2 setae. Telson oblong triangulär, scarcely twice as long as broad, 

 deeply cleft, apices acute. Colour bright carneous red. L. 9 11 mm.
