N" I, 4 and 5 are from Stat. 127 (n" 4 is egg-bearing), n-' 2 is from Stat. 53, n" 3 is from 

 Stat. 240 and bears a Sacculina beneath the abdonien. None of my specimens attains the size of 

 those of Milne-Edw.^rds and de Man (breadth of carapace 9 mm. and more).

This new species much resembles the preceding, but the fronto-orbital breadth is propor- 

 tionately larger, there are always three spiniform teeth at either side of the carapace, e.xcluding 

 the outer orbital angle, the walking legs are more slender, the chehpeds nearly equal, the inner 

 angle of the wrist is produced, and the left palm of the cT lacks the bare, smooth outer surface, ~ 

 so conspicuous in L. setosa. 



The fronto-orbital border is always longer than the length of the 

 carapace; the latter presents scarcely any trace of regions, and, besides with short and 

 widely-separated setae, it is uniformly covered with numerous minute, squamiform granules, 

 visible only on microscopical examination ; these are particularly crowded on the eye-stalks. 

 The shorter hairs near the suborbital and antero-Iateral borders, found to a greater or lesser 

 extent in L. setosa^ are wholly absent, and the whole animal is of a dull, milky-white colour. 

 The proportion of length to breadth is for the rest the same as in the preceding species. 



As usual, the front is strongly deflexed, bilobed and provided with a continuous, trans- 

 verse row of long, silky setae, while similar, but much shorter, hairs are inplanted on the 

 'eye-stalks (fig. 2 a). Contrary to what is found in L. setosa, there is a trace of a rectangularly- 

 cut outer orbital angle, and at equal distances behind it we observe at either 

 side three spiniform teeth, the anterior of which is the larger; between the 

 external orbital angle and the anterior epibranchial tooth the margin is straight or slightly concave, 

 and the distance between the tips of the anterior teeth is scarcely smaller than that between 

 the tips of the next teeth, where the carapace is largest, so that the lines connecting at either 

 side the tips of the anterior and posterior epibranchial teeth are subparallel ; beyond the teeth 

 the margins are blunt and converging somewhat backward. 



The antennulae are comparatively longer and more slender than, and the last joint of the 

 peduncle does not increase in thickness towards the distal end so conspicuously as, in L. setosa. 



The e.xternal maxillipeds (fig. 2 b), which by the way are covered with the same 

 squamiform granules as the carapace, are likewise more slender than in the preceding species; 

 the merus is smoothly rounded off at its antero-external angle, not at all produced, the inner
