Caput discretum, subtriangulatum, f route obtusiusculo. Cephalothorax 

 7-articukitus, segmento septimo brevissimo, postice* obtuso aut obtusius- 

 culo. Oculi superiores remoti, inferiores majusculi, vix elongati. 

 AntenncB anticm cephalothorace breviores, rectos, fere 100° divaricate, 

 20-22-articuIatce, setts totis perbrevibus. Antenna dextra maris pau- 

 lulum incrassata, teretiuscida, fermh 20-articulata. Styli caudales

Head separate, subtriangular, front rather obtuse. Cephalothorax 

 seven-jointed, short and subobtuse behind, head separate, posterior 

 segments four, last very short. Superior eyes distant ; inferior of 

 moderate size. Anterior antennse shorter than cephalothorax, 

 straight, divergent about 100°, twenty- to twenty-two-jointed, joints 

 very short, setae all very short, neither apical nor subapical as long 

 as the joints. Right antenna of male a little incrassate, nearly 

 terete, about twenty-jointed. Caudal stylets elongate, longer than

 second segment the shortest.]

Collected a few individuals in the Pacific, latitude 18° 10' south,
