 lateral margin 6-7-toothed, teeth rather stout, subpyramidal, ob- 

 tuse. Anterior feet equal, carpus coarse nodose, hand tuberculate 

 above, costate without, moveable finger denticulate above. Poste-

Length of carapax of a female, eleven and a half lines; greatest 

 breadth, seventeen and a half lines; ratio of length to breadth, 1 :1'52. 

 The furrows of the surface are deep, and the whole carapax has a 

 rough look. A male in the collections is a little smaller, measuring 

 ten and a half lines in length; and fifteen and a half in breadth; 

 ratio of length to breadth, 1 : 1-5. The abdomen is very much em- 

 bossed, and the sternum also, in the male. The teeth are somewhat 

 irregular. On one side of the male there are the five D, E, N, T, S, 

 and another d', just below the level of D, E. On the opposite side, 

 there is an extra tooth just posterior to T. The line of the lateral 

 margin extends forward to a point some distance below the orbit. 

 On the outer surface of the carpus there are two large rounded tuber- 

 cles. The costas of the outer* surface of the hand are irregularly 

 granulate. The fingers are channeled.
