DISCOVERY REPORTS 



Uropod 3, peduncle stout, one spine on upper inner apex and two spines on upper sur- 

 face between bases of rami, outer ramus almost as long as peduncle, inner ramus shorter. 



Colour (as preserved), white with greyish markings, the most conspicuous of which 

 form a row of spots on the side-plates and on the pleura of pleon segments 1-3, an 

 ocellate mark laterally on each peraeon segment, and a medio-dorsal spot from peraeon 

 segment 3 or 4 to pleon segment 4, eyes grey or pinkish. 



Remarks. This species is distinguished from cornutus and longicornis by the size of 

 the 5th joint of gnathopod 2 in the <$. The specific name refers to the infolding of 

 the 2nd gnathopods across the body in the $, a feature which is also found in e.g. 

 Eurystheus dimorphus and Aora typica.
