six to eiglit articuli. Inferior antennsa more than four times as 

 long as the superior pair ; flagellum as long as the last segment 

 of the peduncle, of about 20 articuli. Anterior gnathopoda with 

 the carpus longer than the propodos, the latter slightly curved 

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

 sHghtly 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, 

 compressed, curved process which lies in an open hollow of the 

 opposed border of the dactylos when the hand is closed. 



Female. — Anterior gnathopoda with the carpus longer than the 

 propodos, both narrow and armed with a few stout setfe. Posterior 

 gnathopoda with the propodos provided with a short rounded 

 projection directed upwards, at the distal end of its dorsal border ; 

 extremity of dactylos scarcely reaching the distal extremity of

Male. — Superior antennae longer than the cephalon ; flagellum 

 rather longer than the last segment of the peduncle, composed of 

 five articuli. Inferior antennae rather more than three times as 

 long as the superior pair ; peduncle stout ; flagellum as long as 

 the peduncle, composed of about 17 articuli. Anterior gnathopoda 

 with the carpus sub -triangular, its infero-distal angle produced 

 into a compressed, rounded process ; the propodos sub-equal with 

 the carpus, much broader distally than proximally, the infero- 

 distal angle produced and rounded ; the palm transverse, armed 

 with short setae ; the dactylos well-developed, shorter than the 

 palm. Posterior gnathopoda large ; carpus minute, propodos 

 heart-shaped, the palm oblique, armed with numerous short setae, 

 and defined by a minute acute tooth. Pereiopoda very thick,
