Differs from T. cymodoce as follows : — 



(1) though the front is of the same general form, the edge of each 

 frontal lobe is somewhat angularly excised and the outer angle is 

 angularly acute (not rounded) and is produced to or even beyond the 

 level of the dentiform inner angle of each lobe : 



(2) the inner angle of the wrist is more acute and spiniform, the 

 upper border of the hand is rounded and the outer surface smooth 

 polished and hairless, and the lower border of the hand is granular or 

 bluntly serrulate : 



(3) the carapace, chelipeds and legs are covered with rather large 

 red spots. 



In the Indian Museum are 5 specimens from Ceylon.
