CYCLOPOIDEA. 2209 



aniicce breviter setulosce. Antennarurn jposticarum articulus 2dus 

 digito brevior, seta nudd elongatd, etiam setd alterd setulosd breviore. 

 Abdomen basi crassum, apice subcylindrico fere quadrujoh longius. 

 Styli caudales vix dimidii abdominis longitudine, setis brevissimis. 



Cephalothorax with the venter carinate. Conspicilla large, very 

 nearly in contact. Anterior antennae short setulose. Finger of 

 posterior antennae longer than second joint, a long naked seta to 

 second joint, another shorter setulose. Abdomen stout at base, 

 linear apex one-third as long as the anterior subelliptical part. 

 Caudal stylets half as long as the abdomen, setae very short. 



Plate 85, fig. 2 a, lateral view of animal, enlarged ; a f , dorsal view, 

 ibid. ; b, anterior antennae ; c, posterior antennae. 



Pacific Ocean, off Duke of Clarence Island, latitude 9° south, longi- 

 tude 171° 30' west, north of Samoa, January 27, 1841. 



Length, one-thirtieth of an inch. Colourless. 



Body rather slender ; in dorsal view broadest in front and narrow- 

 ing behind. As in the preceding, the conspicilla occupy the whole 

 front, and together have the breadth of the animal. The eye-pigment is 

 very much elongated, extending into penult segment of cephalothorax. 

 The abdomen is scarcely narrower at base. The caudal setae do not 

 exceed one-third the stylets in length. 



The anterior antennae are short, and the setae do not exceed half 

 the length of the organ. The second joint of the posterior antennae 

 has one or two short spines on the surface and at apex, besides the 

 long setae ; the naked seta is as long as the joint, the setulose one 

 two-thirds as long. 



The penult or hand joint of the anterior feet is half as long as second 

 joint of posterior antennae. 



Hairs of natatory legs nearly obsolete, being merely a very short 

 pectination of the margin. The abdomen in a lateral view, has the 

 lower side straight to within one-third its length from the apex, where 

 there is a very short spine and a sudden diminishing of thickness.
