 men three-jointed, the third segment abruptly smaller, cylindrical.

 Atlantic, latitude 11° south, longitude 29° west, November 10, 1838. 



Length, one-fifteenth of an inch. 



This species resembles the preceding, but differs in its abdomen and 

 stylets. The fourth segment of the cephalothorax has the acute pro- 

 longations behind one-third those of the preceding joint, and the latter 

 are more than half the length of the abdomen. The anterior antennae 

 have the second, fourth, and sixth joints longer than the others. 



The second joint of the abdomen is broadest at apex, and in the 

 specimen there were above at the posterior part two oval laminae, of 

 large size.
