finally presents no spines save the very small distal one. In all the legs the anterior 

 margin of the carpopodite ends in a distinct spine. In the middle pairs of legs 

 the propodites are greatly elongate, being four times as long (in the median line) as broad, 

 but the dactyli of these legs are even longer than the preceding joints, conical and straight 

 for the greater part. All the dactyli are spinous near the horny, transparent tip. 



The abdomen of the c? (fig. i d) does not taper so much from the third segment to 

 the tip and is on the whole shorter than in the preceding species.

bearing). 



This remarkable species is at once characterized by its finely sculptured chelae, by 

 the lobelike anterolateral teeth of the carapace and by the serration of the meropodites of the 

 ambulatory legs. 



The fronto-orbital breadth is nearly exactly equal to the length of the carapace and 

 twice the breadth of the front; front and eye-stalks together occupy nearly the whole greatest 

 breadth of the carapace (80 — 90 °\^ of the latter), so that the carapace is almost quadrate, 

 much more so than in all other known species of Litocheira. 



The carapace is not much depressed, but vaulted both in longitudinal and transverse 

 direction, smooth, of a dull, milky-white colour, without indications of regions, a straight, 

 cervical groove, bifurcating at each end, being the only furrow; immediately before the cervical 

 groove two spots of a chalky white are observed. The whole surface is covered with the 

 usual long setae, so characteristic of the genus; these setae are particularly long anteriorly; 

 the orbits are connected across the front with a straight row of such setae, that are arranged 

 in two bunches, the middle setae in each of them projecting the most. 



Beyond this transverse row, the front is perpendicularly deflexed, presenting a distinct, 

 but shallow median sulcus, but the anterior margin is not at all bilobed, in anterior view it
