Pseudorostrum with acute antero-lateral processes not quite on a level 

 with the rounded apices and separated from them by an emargination, the 

 sides diverging straight from the processes to the acute 

 forward-directed lateral cornua. From these the carinate 

 sides of the depressed carapace slope rapidly backward 

 to the narrrow hind margin. No distinct median carina, 

 but dorso-lateral carinae from ends of frontal lobe to the 

 hind margin well marked. Transverse ridge from a little 

 behind the cornua reaches the free ventral margin of the 

 carapace. Eye showing no lenses or pigment. Antenna 1 

 with P* joint longer than 2"*^ and 3<^ combined, 3^ longer 

 thau 2^^. Peraeopod 1 not very long, 2"*^ joint the longest, 

 its distal process directed forwards, 5**^ and 6*^ joints 

 equal, each less than one-third longer than the 7^^ joint. 

 Uropods as in E. stelliferum. L. 3-9 mm. § immature.

Pseudorostrum with broadly truncate apices level 

 with or a little in advance of the stout curved lateral 

 cornua, an intervening rectangular process being separated 

 from the apices by a shallow emargination and from the 

 cornua by a semicircular cavity. From the cornua the 

 rounded sides of the pitted and tuberculate carapace 

 converge only slightly to the rather broad hind margin, 

 near to which ;tre a pair of bosses; the median carina 

 on the front half is succeeded by a submedian pair of 

 ridges on the hind part. The 2^'^ pedigerous segment is 

 much lower than the carapace, the 4*^ and 5*^ have 

 each 2 dorsal tubercles. All the segments of the stout 

 pleon have a prominent medio-dorsal carina. Eye of 

 three corneal lenses. Peraeopod 1 has the 2""^ joint about 

 two-thirds as long as the remaining joints combined and 

 is apically produced forwards; the 5*^ joint is a little longer than the 

 6*^1 and nearly twice as long as the 7*'^ Peraeopod 2 has no spine on 

 the apex of the 4"> joint. Peduncle of uropods has two oblique ridges on 

 the dorsal surface and is about half as long as the rami. L. 9 mm <S.
