each with 1 strong, apically bifid spine, fur on 4th, 5th and 6th 

 joints very thick. 



Seventh peraeopod, circlet of serrate spines on apex of 5th joint not 

 well developed, inner margin of 6th joint less furry than in other 

 peraeopods, with 4 strong spines. 



Male appendages on 7th peraeon segment short, apices blunt, 

 distance apart equal to the width of one of them. 



First to third pleopods with 3 hooked setae. 



Male stylet on 2nd pleopod half as long again as ramus, tapering 

 to a fine point. 



Uropods almost three-quarters the length of telson in both sexes, 

 both rami ovate, apically rounded, inner ramus a little longer than 

 outer, with apex slightly more pointed. 



Length: $ 10-5 mm., 5 6 mm.; breadth: $ 5-25 mm., 5 

 3 mm. 



Colour : Very variable : uniform pure white or grey ; or white 

 with head and 1st peraeon segment brown, or peraeon segments 

 1 and 4 brown, or peraeon segments 1-4, pleon and lateral portions 

 of telson brown ; or white or grey speckled with darker ; or grey 

 mottled with darker patches ; or white with purplish-brown trans- 

 verse bands, 1 across head and each peraeon segment, 1 across the 

 united pleon segments 1-4 and 3 more or less curved, across the 

 telson, the last one corresponding with the curve of the distal 

 margin. This last form is characteristic of 5 J , as only one $ 

 with such colouration has been found. The other common form 

 of $ is white with head and 1st peraeon segment brown.

Body very flat, inferior margin of epimera not visible in dorsal 

 view. Head irregularly granular, anterior margin with a fairly 

 deep indentation on either side of median point. Peraeon 

 segments with short longitudinal rugae on lateral portions, the 

 rugae breaking up into irregular granules in centre; 7th segment 

 without any process ; junctions of epimera with body segments 

 rather sunk ; the epimera rather swollen, curved over on to the 

 ventral surface, overlapping (not separated as in E. gig as), 2
