Alcock distinguishes this species from C. hepaticus (Linn.) chiefly by 
“the teeth on the antero-lateral border of the clypeiform expansions ” 
being ‘fin the form of sharp upcurved spines,” by the presence of three 
spines on the postero-lateral border of those expansions, and by some 
of the tubercles on the outer surface of the palm in the chelipeds 
having sharp spinous points. All these characters are present in the 
smaller specimens procured by Mr. Bell Marley in Durban Bay. He 
notes as to one that the colour was “greyish, legs yellow, slightly 
coral-spotted,” of another that it was “darker, only without spots,” 
and that the specimens were obtained “‘near water’s edge, among empty 
shells, in sandy depressions.” One of the specimens had a carapace 
about 17 mm. long, by 27 mm. broad, in another the measurements 
were 15 by 23 mm., thus considerably less than the length of 15 lines 
recorded by Milne-Edwards. But a specimen found ‘‘among rocks,” 
“dark grey, legs yellow,” is about 32 mm. long by 41 mm. broad. 
That it has no sharp spines on the cheliped may be due to attrition.
