portions, separated by an oblique line, running from the base of the movable finger diagonally 

 downward to the carpal articulation: the upper portion presents the same squamiform, though 

 .less regular, markings as already mentioned, the under portion is smooth, ivory-white, continued 

 on the outer surface of the fingers and broken up in its proximal parts into reticulating lines. 

 By this character and also by the general shape of the palm, the chela resembles much that 

 of T. staplctoni de Man, but here the reticulation is reduced to dark, not elevated lines and 

 spreads over the entire surface. The fingers are shorter than the palm, thick, conical, gaping 

 at the base, somewhat spooned and hairy at the tip; the fixed finger is straight, very high 

 proximally, but rapidly tapering to the tip, rather sharp-edged at under border, and provided 

 with 6 — 8 indentations at the cutting margin, but whereas in the right (smaller) chela these 

 indentations are regular, the 3 proximal ones being slightly larger than the 4 that follow, in 

 the left chela there is, parting from the base, firstly an elevated tooth with sloping sides, 

 followed by some 6 — 7 very small indentations between the larger tooth and the tip; the 

 movable finger is curved, and the proximal two-thirds of its back are covered with the same 

 fine granules that accompany the upper border of the palm, the cutting margin is likewise 

 toothed, but on the finger at the right side there are 12 — 13 very minute indentations, not 

 differing appreciably in size; whereas the finger of the left cheliped has firstly three rather 

 large, semi-circular indentations, followed by five much smaller ones. 



Between the bases of the first and second and also between those of the second and 

 third walking leg there are tufts of silky hairs, that apparently mark two openings into the 

 branchial cavity at either side of the carapace, as has been noted already in the description 

 of the preceding species. All the ambulatory legs are nearly equally long, measuring about 

 the distance between the anterior angles of the carapacfe, but much shorter than the chelipeds. 

 The meropodites are 2^3 times as long as broad, narrowing distally, with the anterior distal 

 angle projecting freely and rectangularly, and provided at both surfaces with rather 

 large, oval tympana; carpo- and propodite are together somewhat longer than the 

 meropodite, hairy at both margins; the dactyli finally are conical, acutely pointed, slightly 

 curved and shorter than the propodites. 



Like the preceding species, the colour is a chestnut-brown; the chelipeds are lighter coloured. 



In the general appearance and in the presence of tympana this species approaches 

 T. pusillus (de Haan), but the carapace is comparatively narrower, more convex and not 

 notched behind the external orbital angles, the shape of the abdomen is altogether difterent, 

 the eye-stalks are longer, the maxillipeds much less operculiform and narrower, and the chelae 

 are much more bulky and differently sculptured.
