L.VBOCHIKUS. 109 



posteriorly, thickly at the sides, lightly biiinpressed, its posterior 

 border produced arid widely convex in the middle ; 2nd with 

 spiniform tooth ; most of the sterna nearly smooth in the middle, 

 finely punctured ; punctures becoming more numerous and close- 

 set at the sides. Chelae with coxa almost smooth, weakly punc- 

 tured and striate anteriorly ; trochanter granular, armed below 

 with two teeth in front, and above with four internal teeth, whereof 

 the apical is the longest, and one long anterior tooth ; femur long, 

 subcylindrical, more than twice as long as wide, granular below 

 and internally, smooth and very faintly punctulate above, with a 

 single inferior tooth; tibia thicker than femur, coarsely granular 

 within, rugulose elsewhere, with a distinct anguliform prominence 

 near the base of its lower edge in front ; the apophysis not 

 smooth, posterior border lightly concave, apex rounded and armed 

 above with a long spike; anterior edge sinuous, convex distally 

 and proximally, concave in the middle, and armed distally with a 

 row of about six small close-set teeth : hand smooth above, with 

 the inner edge strongly angled at base, lightly concave and toothed 

 distally ; upper side with wide subgranular depression ; movable 

 finger strongly curved, with a long, nearly straight tip. 2nd and 

 3rd legs without tibial spine. 



2 . First abdominal sternum with wide, central depression 

 which is bordered on each side by a low tuberculiform prominence, 

 coarsely punctured and black behind these prominences. Chelae 

 with femur less granular, not much longer than wide ; hand and 

 tibia normal, smoother ; inner edge of hand with a single tooth; 

 two teeth on the posterior edge of the tibia! apophysis behind 

 the tip; anterior edge lightly convex and toothed throughout; 

 movable finger evenly curved from base to tip. 



Length up to about 32 mm.

J . Resembling the preceding species in colour and most 

 structural features, but with the abdominal sterna closely and 

 finely, but very distinctly granular around the impressions and 

 between them and the border. Easily recognizable also by the 

 different form of the chela : tibia without any basal anguliform 

 prominence below the apophysis ; the latter much less strongly 

 curved downwards, its posterior edge straight, smooth, and con- 

 tinued without curvature to the apex, which is acutely angular and 

 furnished with one long tooth, and sometimes two smaller ones 

 as well, anterior edge straight and finely serrate at the base, 

 then strongly convex and obliquely cut away down to the apex ; 

 hand without impression at base of immovable finger, inner edge 

 with basal constriction much shallower, and anguliform prominence 

 much smaller than in L. proboscideus ; movable finger evenly 

 curved throughout its length as in L. proboscideus $ , not with 

 the apex slightly bent forwards as in the rf of that species.
