Front part broadly arched, back carinate from peraeon segment 5 to 

 pleon segment 4, the keel formiug in each segment an acute backward 

 directed tootb, in pleon segment 4 the back indented in front of the tooth. 

 There is also a similar but much slighter subdorsal keel on either side 

 from peraeon segment 6 to pleon segment 3. Rostrum reaching beyond 

 P* Joint of antenna 1. Side-plates 1 — 5 with acute apices. Pleon segments 1 — 3 

 each having two rather distant teeth at postero-lateral corners. Eyes very 

 prominent, rounded, bright carmine. Antenna 1, 1** Joint longer than 2^ and 

 3*^ combined, flagellum about thrice as long as peduncle, 40-jointed, accessory 

 flagellum 1-jointed, almost rudimentary. Antenna 2 not much longer, ulti- 

 mate and penultimate joints of peduncle subequal, flagellum about twice 

 as long as peduncle. Gnathopods 1 and 2 rather feeble, 5*^ Joint longer 

 than 6*11, palm small, joining bind margin by a rounded angle. Peraeo- 

 pods 1 — 5, uropods 1 — 3 and telson nearly as in E. loricata, but telson scarcely 

 at all longer than broad. Colour whitish with reddish tinge, bind rim 

 of each segment and tips of 4*^ and 5^^ side-plates pink. L. reaching 

 16 mm.

Front part broadly arched, carina from peraeon segment 6 to pleon 

 segment 4 with rather blunt projections, subdorsal keels very slight without 

 dentiform projections, pleon segment 4 with a lateral ridge. ßostrum little 

 overlapping 1^* Joint of antenna 1. Side-plates 1—3 and 5 with blunt 

 apices, 4*^ less produced and less distinctly falcifoxm than in other species. 

 Pleon Segments 1 — 3 with 2 distant. not very shai*p, teeth at postero-lateral 

 Corners. Eyes rounded, light carmine. Antenna 1 short, 1^* Joint much 

 longer than 2'^ and 3^ combined, flagellum about twice as long as peduncle, 

 24-jointed. Antenna 2 considerably longer, ultimate Joint of peduncle shorter 

 than penultimate, flagellum 2^/2 times as long as peduncle. Gnathopods 1 

 and 2, B^^ Joint considerably longer than 6*^, which is naiTow, scarcely 

 widening distally. Peraeopod 5, 2^ Joint not nearly as long as remainder 

 of leg, ending in a blunt lobe, üropod 3 as in E. cornigera. Telson 

 rather broad, scarcely longer than breadth at base, slightly emarginate 

 between 2 blunt apices. Colour whitish with faint rosy tinge (Sars), clear
