Remarks. This species closely resembles E. grimaldii in the shallow convexity of the anterior margin 

 of the carapace and in the size and shape of the eyes, with the corneal elements occupying the outer 

 distal region of the eyestalk, so that they look essentially outward and the proximal margin of the cornea 

 is decidedly oblique (cf. Figs. 4 A and 5 A). It may be distinguished from grimaldii (i) by its smaller, 

 more slender form, (ii) by the shorter inner margin of the third segment of the antennular peduncle
