GAMMARIDEA. 937 



half the body, second joint much the longest, flagellum nearly twice 

 as long as base, about fourteen-jointed, joints long, setae very few 

 and short; inferior pair shorter than superior, base much longer 

 than base of superior, fourth joint longest, and about as long as 

 flagellum. Anterior hands small, oblong, narrow, narrower at 

 apex. Hands of second pair stout, broad subrectangular, transverse 

 at apex, the palm being apical, little excavate and unevenly so, in- 

 ferior angle prominent and acute, finger moderately large. Third 

 and fourth pairs of feet quite short ; sixth and seventh subequal, 

 fifth much shorter, setae very few, rather short, basal joint a little 

 broad, proportion ably broadest in fifth pair.

Sooloo Archipelago. Dredged up in six and a half fathoms water, 

 February 2, 1842. 



Length, three lines. Colour, reddish. The superior antennae three- 

 fourths as long as body; third basal joint half the preceding in 

 length. The third joint of inferior pair is about one-third whole 

 length of antenna. Joints of flagellum of superior antenna long ; of 

 inferior pair about half as long as in superior. The finger of the large 

 hand shuts against the terminal transverse margin, not fitting close to 

 it; just above the lower angle there is a small obtuse prominence, and 

 about this angle and the palm there are a few very short setae. The 

 carpus has a very narrow process below, between the hand and the 

 third joint. The small hand has the apex obliquely truncate to form 

 the palm, and the finger is a little longer than this margin, so as to 

 project beyond ; the superior and inferior margins are about parallel. 

 Apices of the caudal stylets nearly in same line. 



The fifth pair of legs and also the sixth had the extremity inverted 

 in the specimen figured.
