BRACHYURA. KATHBUN. 127 



Description. Carapace moderately convex from side to 

 side, and not strikingly so from front to back ; covered with 

 soft, uneven, and rather short hairs, which do not conceal 

 the unevenness of the surface below ; interregional grooves 

 deep ; gastric region divided into three ; two areoles on the 

 anterior branchial region. Middle lobes of front oblique, 

 separated by a deep, narrow notch, edge sparsely and 

 minutely spinulous ; outer tooth triangular, tipped with a 

 white spinule and separated by a right-angled sinus from 

 the blunt, inner angle of the orbit. Upper margin of orbit 

 hairy, feebly bi-emarginate, a small tooth tipped with a 

 white spinule at outer angle; below this a broad V- sinus; 

 lower margin sparsely spinulous; outer half transverse, 

 inner half advancing gradually to the spine-pointed inner 

 angle. A subhepatic spine a little longer than the outer 

 orbital one. Behind it three conical, curved spines with 

 sharp white tips. 



Chelipeds of female unequal, the left palm two-thirds 

 as high as the right; the exposed surface is hairy, except 

 on the fingers; nierus with two spines above, at, and near 

 the distal end, upper and lower edges obscurely roughened, 

 proximal end of inner margin as well as the inner margin 

 of the ischium spinulous. The carpus and upper proximal 

 half of the maims are armed with strong and rather sparse 

 spines, which form the centres of clusters of hairs; on the 

 carpus four or five of the spines run along the distal 

 margin and the largest one is at the inner angle; on the 

 lower, distal half of the manus the spines become smaller, 

 more tuberculiform, and more numerous, reaching quite 

 under the lower surface and part way on the immovable 

 finger; this finger of the major chela is much broken, its 

 lower line is continuous with the horizontal line of the 

 palm until near the tip, which bends gradually upward ; 

 the dactylus has a deep groove a little below and parallel 

 to the upper margin, the basal two-fifths of its upper 

 surface is spinulous. The immovable finger of the minor 

 chela is slightly deflexed before it turns upward at the tip ; 

 the spinulation and hairiness of the fingers are more 

 extensive than in the larger chela. 



Ambulatory legs covered with hairs like those on the 

 carapace and also long hairs w 7 hich are disposed chiefly 

 along the margins.
