Body rather stout, epimerals broad, but fifth slightly shorter than 

 fourth ; abdominal segments unequally denticulate on back margin. 

 Eye subrotund. Antennae having the bases long, subequal, and the 

 joints of the flagella oblong, and setae not shorter than the joints; 

 superior pair with the first joint of base quite stout, second slender, 

 nearly twice as long as first, the third much shorter, appendage 

 three-jointed. Inferior antennae about half as long as body, base 

 very slender, the last two joints subequal, flagellum a little shorter 

 than base. Anterior feet very small, hand minute, oblong, attenuate. 

 Second pair more than twice the length of the first, dense hirsute 

 below ; hand oblong, margins nearly parallel ; palm much oblique, 

 finger half the length of the hand ; carpus shorter than the hand.

Dredged up in six and a half fathoms, Sooloo Archipelago, February 

 2, 1842. 



Length six lines. The denticulation on the back of the abdomen is 

 irregular, and is not confined to the posterior margin of the segments. 

 The first joint of the superior antennae is twice as stout as the follow- 

 ing. The first two joints of the inferior pair are very short, the first 

 projects below the second to about half the length of the latter. The 

 setae of the organs are mostly about twice as long as the diameter of 

 the joints. The hand of the first pair is nearly a fourth narrower 

 than that of the second. The hand of the second is hirsute in many
