in ? 12 : 8, in $ coffin-shaped, with a small niedio-dorsal tubercle iu 

 the anterior half and another near the posterior margin, the latter 

 hook-shaped and pointed backwards, some granules larger than the 

 rest along the lateral margins, in ? slightly wider anteriorly than 

 posteriorly, sides nearly straight, a low rounded medio-dorsal tubercle 

 in the anterior half and another on the posterior margin, the posterior 

 margin itself somewhat thickened and elevated ; segments 5 and 6 with 

 rounded side-plates only partly visible in dorsal view, segment 5 in 

 with a small median tubercle on both anterior and posterior margins, 

 segment 6 in $ with one on the posterior margin only, segment 7 with 

 subacute side-plates. 



Pleou segments 1-3 slightly widening, but 3 not laterally projecting, 

 its posterior margin distinctly trilobed, telson tapering to a truncate 

 apex. 



Antenna 2, 2nd joint toothed on outer margin, 3rd and 4th iu 

 adult $ tuberculate on inner lower surfaces, 1 or 2 tubercles also on 

 5th, this latter joint in ? with very minute denticles on lower inner 

 margin ; flagellum 2-joiuted, with 2 rows of small denticles on lower 

 surface. 



Peraeopods 2-4 relatively long. 



Peraeopod 5, 2nd joint scarcely equal to width of segment 4 and 

 shorter than all the other joints together. 



Marsupial plates, three pairs, inset piece of that on 4th segment 

 extending along whole posterior margin, setulose. 



Male appendage on pleon segment 1 apically blunt. 



Pleopod 2, male stylet half as long again as ramus, rather stout,. 

 apex deeply bifurcate in adult, acute in immature specimens. 



Concealed ramus of tiropod with 3 setae.

Stebbiug received his specimen from Port Elizabeth. 



In this species there is some variation, albeit slight, in the develop- 

 ment of the dorsal tubercles, especially on segments 5 and 6 in
