Anterolateral spines of carapace scarcely reach posterior margin 

 of cornea, in some specimens a little beyond this level. Anterolateral 

 angles of all three hepatic lobes well marked, at least the first (in the 

 type all three) sharply acute and spined ; first spine long and slender 

 and appreciably exserted; the second about half the length of the 

 first ; the third in the type as much reduced again. 



Large hand quite smooth appearing, only very finely scabrous,

the posterior upper angles of the palm to meet and become one about 

 the middle of the length of the palm, shortly thereafter to fade out

 No lobe on outer margin of movable finger near base ; tooth on fixed 

 finger well developed. Virtually no palmar crest, inner margin of 

 palm more or less obsolescently and rather broadly carinated, carina 

 armed anteriorly with a sharp corneous spine. 



Carpus of cheliped with acutely spined lobe at anterior-internal

 strong spines; at anterior end this row of spines appears to turn
