men is five-jointed, the first segment with an acute spinous process on 

 the right, and the last very short. The last four joints of the anterior 

 antennae increase in length to the last. The smaller branch of the 

 posterior antennae terminates in five setae. The pencil of hairs of the 

 maxillae, directed backward, is much shorter than in the ornata. 



The maxillipeds have two short stout setae on the inner margin of 

 the first joint, two on the inner margin and one at the apex of the 

 second joint, and two to the last joint.

Pacific, latitude 9° south, longitude 174° west, near Duke of York's 

 Island, January 26, 1841; also, near Hall's Island, Kingsmill Group. 

 April 14, 1841; also, in the Sooloo Sea, January 28, 1842. 



Length, one-twenty-fourth of an inch. Body, slightly brownish 

 black; natatories, black or brownish black; antennae, dark colour, 

 except basal portion. The two antennae, after the curve at base, are 

 nearly in the same straight line, very slightly advanced beyond it; 

 the apical joint is bent a little forward out of the line of the antenna; 

 most of the setae are three or four diameters of the joints in length ; 

 apical joint longest; penult three-fourths the apical in length; ante- 

 penult one-third the apical, and a little shorter than the next pre- 

 ceding. Length of second joint of the antenna three or four times its 



diameter.
