hindmost tooth of the antero-lateral margin is very small and less 
prominent than the penultimate. The fingers of the chelipeds are dark 
with white tips, but so far differing from Krauss’s account that they 
are not sharp. 
Miers notes this species doubtfully as a synonym of Leptodius 
exaratus (Milne-Edwards). Mr. Bell Marley sends it from Durban, 
where also it has been taken by Mr. D. R. Boyce.

This species has been already recorded as taken at Durban by Mr. 
H. W. Bell Marley. It has been taken in the same locality by Mr. 
D. R. Boyce. The large pad of felt on the outer side of the large hands 
of the chelipeds is a notable feature. The ambulatory limbs are very 
short; the two anterior teeth of the antero-lateral margins of the 
carapace are very obtuse.

Mr. Bell Marley has favoured me with a large male specimen from 
Durban Bay, and describes the colouring as “ blackish-green, with 
brown and white markings and spots.”
