margin of the ischium is serrate; the exognath is slender, measuring only one-half of the 

 breadth of the ischium. 



There is scarcely any difference in size between the cheHpeds of the young cf and the 9, 

 but in the only apparently adult cf specimen the right (not the left, as in L. sctosa) is some- 

 what larger; all the joints are covered with numerous flat granules, that are somewhat raised 

 and sharpened on the outer surface of the palm. The meropodite is short, upper and inner 

 border sharpened, the former much curved and entirely unarmed near its distal end, the inner 

 border with 8 — lo spinules; the inner angle of the wrist is sharpened, somewhat produced, 

 the tip being directed forward; the palm is granulate at the outer surface, longer than high 

 and longer than the fingers, upper and under border are rounded; the outer surface of the 

 fingers is longitudinally grooved, and of a brown colour, but much less so than in the preceding 

 species, the immovable finger whoUy straight, conical, tapering to a fine tip, that is sharply 

 curved upward, the movable finger is more curved towards the tip, granulate on the back ; 

 the cutting margins of both fingers are finely crenulate, in the case of the upper finger it 

 is the first tooth, near the base, and in the case of the under finger the second, that is the 

 largest (fig. 2 c). 



The walking legs again much resemble those of the preceding species; the penultimate 

 pair is 2.75 times as long as the carapace. The meropodites are wholly unarmed; four 

 times as long as broad; the propodites are elongate, even those of the last pair of legs, and 

 the dactyli are as long as the propodites, rather thick and conical, with the tip curved, free 

 from setae and of a horny colour; in the case of the last pair of legs the dactyli are armed 

 with some minute spines near the end of the outer border and also with a few spinules at the 

 inner side, near the tip (fig. 2d). 



The first segment of the abdomen of the cf wholly covers the space between the coxo- 

 podites of the last pair of legs, the second segment is narrower and the third again as broad 

 as the first; from here the abdomen gradually tapers towards the tip. All the segments are 

 very distinctly separated.
