and the corner not produced. Carapace sometimes with minute denticle dor- 

 sally one-third of length from front. Pleon segments without ventral setae. 

 Hind margin of telsonic segment, in Q only, carrying 4 — 6 conspicuous setae. 

 Antenna 1 9 nearly as in E. deformis (nr. 1), but 1 -jointed accessory equal 

 in length to 1^* joint of principal flagellum (H. J. Hansen), considerably 

 shorter than that joint (Smith) though relatively larger than in E. deformis; 

 in d flagellum 4-jointed, accessory 2-jointed. Peraeopod 1, 1^^ joint little 

 shorter than 6^*^. Uropods, like the limbs, less robust than in the preceding 

 species; peduncle in both sexes shorter than the endopod, in which the 2"*^ joint 

 is half as long as the P* in Q, a little less in 6, where both joints are 

 strongly setose; exopod considerably longer, tapering, slightly curved outward 

 at the apex, carrying several setae on distal part of medial margin and at 

 the apex, very long and closely set in the 6 . L. 9 about 5 mm, 6 a very 

 little longer.

Pseudorostral lobes directed upwards with slight inclination forwards, 

 distal end truncated, in lateral view a broad triangle rising above the dorsal 

 line of the carapace, frontal margin coarsely serrate, receding to the small 

 antero-lateral tooth which defines a very small sinus. Carapace with forward 

 pointing median tooth near the end, the sides traversed from end to end 

 by a curved ridge. Antenna 1, 1 -jointed accessory as long as 1^* joint of 

 3-jointed principal flagellum. Peraeopods 1, 2 short. Uropods short and 

 stout, exopod nearly twice as long as peduncle, roughened on surface 

 with irregular tubercles or blunt teeth; endopod only a little shorter, P*^ 

 joint twice as long as 2"*^, apical spine long and stout. L, 9 1-75 mm, d 

 unknown.

4. E. biplicata Calm. 1912 E. b., Caiman in: P. U. S. Mus., v. 41 p. 625 

 tf. 25, 26. 



Pseudorostral lobes nearly vertical, acute, front margin concave. Cara- 



/pace little longer than deep, front margin sinuous with 

 upper part faintly serrate, sides having each 2 oblique 

 curved ridges. Pedigerous segment I flrmly united to 

 the carapace. Telsonic segment about as long as the 

 short broad peduncle of the uropods, the produced 

 portion broadly rounded and marked off" by a distinct 

 transverse groove. Maxilliped 3 with 2"<^ joint nearly 

 twice as long as the rest combined. Peduncle of 

 uropods scarcely two-thirds as long as the exopod, 

 which has the apex narrowed and curved outward; 

 ^^ the rather shorter endopod has a 1^* joint thrice as 



E. biplicata Caiman, ^oug as the 2''^, wMch is tipped with a short stout 



telson and uropod. Spiue. L. 9 5'5 mm, C? UukuOWU.
