TO INDIAN CARCINOLOGY. 353 



from the Red Sea, in the British Museum, which I have examined, the carapace and 

 chelipedes are covered with numerous small depressions or pits, giving them a rugose 

 appearance, and this character is wanting in the present species; otherwise the two 

 are nearly related.

These agree with A. Milne-Edwards's figure and brief description, though they have lost 

 the vivid colour shown in the former. The pearly granulations show a tendency to 

 linear arrangement on the hands. A wide hiatus exists between the iiugers, and their 

 margins are toothed. The inner border of the carpus carries tAvo strong granulated and 

 blunt teeth. The largest specimen has the carapace 17 mm. long and 27'5 mm. broad.
