Head, lateral angle little prolonged, rounded. Side-plate 1 broader 

 and deeper than the 2 following. Pleon segment 3, postero-lateral corners 

 slightly produced backward, quadrate, 4*^ slightly gibbous. P^yes wanting. 

 Antenna 1, flagellum 4-jointed, with long setae, accessory flagellum 2-jointed, 

 Antenna 2, penultimate Joint rather longer than ultimate of peduncle. Gnatho- 

 pods 1 and 2 apparently as in S. robertsoni. Peraeopod 5, 2*^ Joint widely 

 expanded behind and produced downward to middle of 4^^, its margin dentate. 

 üropod 3, rami smooth, a little longer than peduncle. Telson as broad as 

 long, cleft to the centre. L. 2 mm.

None of the side-plates especially large. Mandible broad and short, 

 the cutting edge strongly dentate, secondary plate ou left mandible also 

 strongly dentate, molar denticulate, palp central. Maxillipeds, inner plates 

 with more than 3 apical teeth, outer plates at apex acutely produced. inner 

 margin without teeth, P* Joint of palp not shorter than 2\ Gnathopods 1 and 2 

 subchelate, the 2*^ little weaker than the 1^* and of similar structure except 

 in having the 3*^ Joint elongate. Peraeopods 3—5, with the 2'^ Joint so 

 little expanded, that these limbs are not imbricated as usual, but stand apart, 

 üropods successively shorter, rami of each pair unequal. Telson short, broad, 

 cleft beyond the middle.

Side-plate 4 little excavate behind. Pleon segment 3, angles acute, 

 a little upturned, 4*^ with dorsal depressiou followed by small distal hump. 

 Eyes jiot observed. Antenna 1, peduncle short, stout, 1^* Joint scarcely longer 

 than broad, flagellum with 13 or 14 joints, 1^* subequal in leng-th to peduncle, 

 accessory flagellum with 1 long and 3 short joints. Antenna 2 subequal in length 

 to antenna 1, ultimate Joint of peduncle shorter than penultimate, flagellum 

 14-joiuted. Maxilla 1, inner plate with 5 short plumose setae. outer with 8 or 9 

 slender spines, 2^ Joint of palp long, with 6 spine-teeth. Maxilla 2, with about 

 12 spines on each plate. Gnathopod 1, 3^ and 4*^ joints short, 5*^ shorter 

 than 6^'», which is oblong, not 1^2 times as long as broad. palm rather deeply 

 concave, 7*^^ Joint curved, not massive, impinging on palmar spines. Gnatho-
