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

 breadth, seventeen and a half lines; ratio of length to breadth, 1 : 1'62. 

 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 - f 

 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 arc 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 costse of the outer surface of the hand are irregularly 

 granulate. The fingers are channeled.
