Carapace broad, little convex, its length a little more than half its 

 breadth without the great lateral spines, at all ages closely covered 

 with largish miliary granules : two transverse lines on the gastric, one 

 on either branchial region ; sometimes two lumps on the cardiac and 

 one on the post-gastric region, these being very variable in size and 

 distinctness.
