in a rounded knob, while its inner margin is produced into a 

 strong ridge standing almost at right angles to the joint and 

 running out into a distinct spine. The flagellum reaches 

 slightly beyond the spines of the rostrum. 



The external maxdli'peds are so thickly covered with felted 

 hairs that only the line of junction of their second and third 

 joints is seen, and this stands out as a tumid white projection. 

 The inner half of the second joint is produced upwards and 

 the outer half of the third joint downwards, the whole forming 

 a closely-locked articulation. 



The cheUpeds are shorter than the first pair of ambulatory 

 legs ; the meros bears a 'ie.vf spinose tubercles on the outside 

 and one acute tooth at its widened extremity between the 

 prominent joint tubercles ; the carpus has several tubercles on 

 the outer surface, but is not ridged ; the hand is quite smooth, 

 externally slightly concave, on the inner side produced into 

 a broad median elevation, above which is a long blood-red 

 patch, all the rest of the joint being white ; fingers acute at 

 their extremities, smooth internally. 



The ambulatory legs are very long, slender, and smooth ; 

 the meros of the first pair as long as the two succeeding 

 joints ; the dactyla cylindrical, slender, rugose towards the 

 extremities and ending in smooth yellowish-brown claws. 



In colour the carapace and legs are whitish grey, with 

 blood-red spots ; the hands also have a characteristic blood- 

 red patch on the upper inner side. 



Female. — The body is smaller in every way, the chelipeds 

 are very much shorter than the first pair of ambulatory feet 

 and are very slender.
