The posterior margin of the meropodites of the first pair are armed in their distal half with a row 

 of 6 — 7 spines, the penultimate of which is by far the larger; in the middle third of the same 

 margin of the second pair three much smaller and widely-separated spinules are found ; the 

 meropodites of the two following pairs are entirely spineless. In the adult 9 (Stat. 131) all the 

 spines are less in number. 



The dactyli of the posterior legs show several spines near the horny, transparent tip, 

 similar to, but longer than, those of L. affinis. 



The third segment of the abdomen of the cf (fig. 3 c) reaches as far outward as the 

 first; the second is only slightly narrower. 



Zehntner's specimen (a 9) came from Amboyna. Alcock records a specimen from 

 the Andamans.

This species is readily disting-uished by the long, slender, spider-like and spinulous 

 walking legs and by the narrow external maxillipeds. 



The carapace is decidedly broader than long, but less so than in L. quadrispiuosa, 

 the ratio of length to greatest breadth being i : 1.25 — 1.3 and in the preceding species 

 I : 1.35 — 1.45. The fronto-orbital border in the present species is also broader than the length 

 of the carapace. The latter itself is more convex than in L. qiiadrispinosa and covered with 

 numerous soft setae ; these are, however, shorter than usually is the case : in the cf here figured 

 (Stat. 250) the hairs are very inconspicuous and short, even on the surface of the front, in 

 the 9 they are longer, but not arranged in a distinct transverse row across the front. Regions 

 are .scarcely to be made out, onl)- the cervical groove being visible, but behind the front traces 

 of two epigastric lobes, separated by a longitudinal furrow, that bifurcates backward, may be 

 seen. For the rest the whole surface of the carapace seems to be smooth. The front is 

 strongly deflexed ; the anterior margin is bilobed, though this is scarcely visible in dorsal view ;
