1. E. doUfusi Calm. 1907 E. cl, Caiman in: Bull. Mus. Paris, p. 119 tf . 2— 4. 



Pseudorostrum apically emarginate in dorsal view, sides gently convex. 

 Carapace not much longer than broad, leaving free only 3 pedigerous segments, 

 the lateral cornua not level with apex of pseudorostrum, lateral margin behind 

 them carinate, and breadth slightly encreased. Pedigerous segment 2 slightly 

 detached from carapace at sides only. Pleon slender, smooth like the rest 

 of the body, telsonic segment shorter than the preceding. Eyelobe small, 

 without pigment. Peraeopod 1 short, 2"'^ joint longer than the remaining 5 

 combined. Uropods with rami almost 3 times as long as the peduncle. L. 9 

 6-45 mm (specimens not adult).

 sur-Mer, in the sand.

 zool. Soc. London, v. 18 1 p. 20. 



Pseudorostrum apically notched in dorsal view, sides sinuous, extending 

 much beyond the small incurved lateral cornua. From these the greatest 

 breadth of the carapace diminishes to the base greatly in 9, moderately in d, 

 the sides sharply inflected, with oblique ridge running from the cornua to 

 the free margin of the flattened ventral surface; a slight medio-dorsal ridge 

 i« more prominent anteriorly in 9, posteriorly in d. First pedigerous 

 segment not distinguished from carapace unless by fauit dorsal marking, 

 2'^*^ fused but with complete suture. Pleon much more slender in 9 than 

 in d, 5*^ segment longer than 6^\ its width in 6 abruptly decreasing at 

 middle. Eye with 3 corneal lenses, larger in d. Antenna 1 with P* joint 

 angularly bent, third longer than 2"*^, shorter than J ^^ flagellum 2-jointed 

 in 9, 3-jointed in d. Antenna 2 9 a rounded nodule bearing 2 plumose 

 setae. Lower lip with broadly rounded lobes. Maxilla 1 with 2 apical filaments 

 on palp. Maxilliped 1, exopod normal, epipod with branchial sacs in straight 

 line, 22 in 9, 33 more elongate in d. Maxilliped 2 with 3*^ joint distinct 

 though small. Maxilliped 3, 2^^^ joint greatly produced outside the 3*^ and 

 4*'^ 3^1 unusually large, in figure longer than the 4*^^ 4*^ produced along 

 lateral margin of the narrow 5*'\ Peraeopod 1 long, 2"'^ joint abruptly narrowed 

 distally and apically produced, acutely on the medial edge beyond the third 

 joint. Peraeopod 2 the shortest, its 3*^ joint suppressed, the 4*^^ apically 

 produced and tipped with a long spine. Peduncle of uropod less than half 

 as long as the subequal rami, both minutely knobbed at apex, endopod in 9 

 with a few plumose setae and spiuules on medial margin, in d densely set
