the carpus produced below into a rounded prominence, the

 with the carpus longer than the propodos, the latter slightly curved 

 downwards, narrow, of nearly uniform breadth from end to end, 

 slightly dilated at the infero-distal angle; palm transverse; 

 dactylos longer than the palm. Posterior gnathopoda with the 

 propodos large, heart-shaped, the palm oblique, armed with short 

 bristles, and provided near the distal end with a prominent,

 opposed border of the dactylos when the hand is closed.
