This species is easily recognisable by the dentation of the antero-lateral borders, by the 

 rows of spines on the meropodites of the walking legs and by the characteristic dark markings 

 on the body. These features are so reliable that I do not doubt of the identity of my specimens 

 with Zehntner's species, which, for the rest, was founded on a young 9 only, but nevertheless 

 they do not in all respects answer to description and figure of the -Swiss author. 



The convexity, or rather the depression, of the carapace and the covering of the lono-, 

 silky and transparent setae are the same as in the other species of Litoclieira. The only trace 

 of regions to be detected is the long concave cervical groove, otherwise the carapace is smooth, 

 sparsely covered with setae, that become larger towards the orbits and the front, and with 

 widely-separated granules. Very characteristic are some dark markings on the 

 lightly- yellow carapace, as has been, put forth by Zehntner and Alcock: firstly there is 

 a most conspicuous horse-shoe .shaped spot behind the front, the lateral parts of which spot vary 

 in thickness in different individuals: in the largest cf (Stat. 248) this figure assumes the shape 

 of two obliquely-longitudinal, pear-shaped, large blotches, contiguous at their anterior end; further, 

 similar, but much more irregular markings extend along the antero-lateral margins of the carapace, 

 on the subhepatic and subbranchial regions, on the epistome and on the under side of the eye- 

 stalks, but their distribution varies much individually, and again in the cT of Stat. 248 they 

 are the most developed. Zehntner mentions and figures traces of epigastric lobes, which were, 

 however, absent in my individuals. 



The front is not so much deflexed as in the preceding species, so that the deep sinus, 

 dividing the anterior margin into two obliquely-sloping lobes may be largely detected in dorsal 

 view of the carapace; these lobes are, however, much more distinct in anterior view of the 

 animal and it is then stated that each of them projects in a sha.rp angle near the lateral end. 

 The supra-orbital border is twice emarginated by a triangular notch, one situated 

 in the middle and the other quite near the outer orbital angle ; the fronto-orbital border is very 

 large, occupying 0.8 — 0.9 of the greatest breadth of the carapace, not including the antero- 

 lateral teeth. The outer orbital angle is a small, obtuse lobe, not projecting beyond the level 

 of the supra-orbital border, and not so sharp and prominent as shown in Zehntner's figure. 

 Behind this angle the margin is very deeply concave, then turns forward again to form the 

 first antero-lateral tooth, which, like the slightly smaller second, is large, spini- 

 form, turned straight forward in its distal half and reaching nearly to the 

 level of the outer orbital angle; the distance between the tips of the second pair of 

 teeth is scarcely greater than that between the first pair. Behind the last teeth the margins 

 are obsolete, subparallel to each other, then slightly converging towards the base of the second 

 pair of walking legs. 



The antennulae are rather short and thick; the last joint of the peduncle greatly increases 

 in bulk towards the distal end, as in L. setosa. The flagellum of the antenna is long, measuring
