more than twice the length of the eye-stalk, but not as long as the carapace (Zehntner) and 

 the o-reater part of the 17 joints of which it is composed bears a wreath of several long setae, 

 similar to those of the carapace and the legs. The flagellum is rendered conspicuous 

 by the same s e p i a - b r o w n colour as shown b \- the various markings of 

 the carapace, this hue may be, however, absent on account of its having been extracted by 

 alcohol. The external maxillipeds (fig. 3^) are more slender than in the two preceding species, 

 but otherwise very much alike to those of L. affinis : the antero-external angle of the merus is 

 rounded, rectangular, not at all prominent; the exognath measures near its base not yet one- 

 half of the breadth of the ischium. The lateral margins of the buccal cavern are parallel. 



The chelipeds are unequal in the adult, the left being the larger, as in L. sctosa, both 

 in the cf and in the Q; in the c? figured here (Stat. 193) only the left cheliped is present, 

 but this happens to be unusually small and the ratio may here have been the reverse. 

 According to Zehntner they are equal (in 9). The short meropodite is sharply-edged at upper 

 and particularly at inner border, the former is armed with a strong, curved tooth near the 

 distal end, preceded in the proximal half of the border by a series of much smaller spines, 

 and similar spines are found in a single file along the inner border of both ischio- and mero- 

 podite; the outer surface of the latter is granulate, like upper portion of wrist and outer 

 surface of palm. Inner angle of wrist sharply produced, turned forward. Both in the larger and 

 in the smaller chela, but more distinctly so in the latter, the granules of the outer surface 

 present the tendency of arranging themselves in longitudinal rows, but it is remarkable, that 

 in the unusually small chela here figured (fig. 3^) nothing of this kind is observed, the palm 

 is longer than the fingers and the borders are rounded. Near the base of the immovable finger 

 of the large chela and along the under border, in the case of the adult specimens, the same. 

 perfectly smooth, naked, ivory-white portion is developed as has been described in L. sctosa. 

 Also with regard to the fingers the two species resemble each other: the immovable finger of 

 the large chela is perfectly straight, save the curved, acuminate tip, very high at the base and 

 rapidly tapering, the opposite finger is granulate on the back, near the base, faintly curved in 

 the proximal two-thirds, more strongly so towards the tip, the cutting margins of both fingers 

 are roughly crenulate; in the right chela the fingers are somewhat lower at the base and 

 the crenulations are sharper, turned forward and decreasing from base to tip of the inner 

 margin (see also Zehntner's figure \\b)\ in both chelae the fingers are coloured generally a 

 chestnut-brown, but in the 9 of Stat. 131 they are simply ivory-white, like the apparently 

 discoloured antennae. 



The strong walking legs afford nothing remarkable but the characteristic spines 

 on the meropodites. The number and disposition of these spines offer individual variations, 

 but in the adult cf of Stat. 248 I observe the following: the anterior margin of the first to 

 third pair inclusive ends in a spine and, besides, in the distal half of the first and second pair 

 agam two spines, close to one another, are found, the distal one of which is the larger, the 

 third pair bears only a single spine at the beginning of the distal third of the margin; the 

 meropodites of the fourth pair finally are entirely unarmed. Among the long setae fringing 

 the anterior margins of all the meropodites some long, feathered hairs are to be observed.
