Diagnosis. — Carapace covered with 

 numerous fine granules. Middle lobes 

 of front with narrow elongate tips. Ono 

 antero-lateral tooth. Inner suborbital 

 tooth not exceeding pterj^gostomian lobe. 

 Chelipeds tuberculous. 



Description of immature female. — 

 Carapace everjAvhere covered with fine 

 contiguous granules among which are 

 some larger, more elevated granules. 

 Like C. gracilipes^ there is only one an- 

 tero-lateral tooth, and in the same posi- 

 tion but smaller. Median sinus of front 

 deep, triangular, median lobes very nar- 

 row or bluntly spiniform at extremity; 

 at their outer base, a tubercle. Supra- 

 orbital lobes small, triangular, separated 

 by rounded sinuses. Outer lobe of orbit 

 short, not reaching middle of cornea. 

 Outer suborbital lobe low, broad, trian- 

 gular, subacute, separated by a Avido 

 sinus from the exorbital lobe and by a 

 wider, deeper sinus from the inner lobe, 

 which Avas probably inconspicuous (speci- 

 men damaged). Pterygostomian lobo 

 wide, very prominent and doubtless 

 visible in dorsal view. E3'e remarkably 

 large, the corneal part wider than long, 

 the peduncle dorsally flattened.
