Male. — In the right fifth foot the terminal hook of the exopodite 

 is divided at the tip, making an imperfect chela. The endopodite is 

 2 segmented, angular; the proximal segment has a blunt internal 

 projection near the base and the distal segment is notched at the 

 end; the endopodite exceeds in length the first two segments of the 

 exopodite. 



The second segment of the left exopodite, as shown by Sars, has 2 

 spines instead of 1 as is customary in this genus. The second basal 

 segment of the left fifth foot has a smooth lamella projecting from its 

 inner surface. The endopodite is 1 segmented, short, and lamelli- 

 form. Figure 19 shows the fifth feet according to Searle.
