Locality uncertain. 



Length of carapax of female, seven lines ; greatest breadth, ten and 

 one-fourth lines; ratio, 1 : 1*46. The carapax is rather rough and 

 uneven about the antero-lateral region towards the margin, and the 

 other areolets have interrupted rugae of granules, or scattered isolated 

 granules. The most striking character is in the bicristate fourth joint
