In close general agTeement with E. monoculoides (p. 345), but the large, 

 reniform eyes are white with a faint rose tint; in antenna 1 the 3^ Joint is 

 more than half as long as the 2^; maxilla 1 has only one seta on the* 

 inner plate and only one ou outer inargin of the palp's 2*^ Joint; maxilla 2 

 has the inner plate shorter and narrower than the outer. Colour grey, tinged

DifferiDg little from E. monoculoides (p. 345). Pleon segmeuts 1 and 2 

 not produced into teeth dorsally, but formiug a small acute tooth at postero- 

 lateral corners, segment 3 with those corners almost quadrate, with no 

 serration. Eyes very large, reniform, almost contiguous at top of head. 

 Maxilla 1, inner plate long and narrow, with 3 setae, 1*^* Joint of palp half as long 

 as 2^, 2^ with 1 seta on outer raargin. Gnathopods 1 and 2, 6*^ Joint dilated 

 about the middle, so that the palm instead of being continuous with the 

 bind margin forms a well-marked obtuse angle with it. Telson shorter 

 than in preceding species, cleft for less than half its length, evenly tapering 

 to subacute apices, which in the Single specimen were simple, without any 

 notch. L. about 15 mm.

 with 11 spines, 2*^ Joint of palp not widened distally. Maxilla 2, inner plate 

 loroader than outer. Maxillipeds, inner and outer plates not very large, 

 armature normal, palp long. Gnathopods 1 and 2, 5*^ Joint short, lobed,
