4*^ much the largest, strongly emarginate. Pleon segmeut 3, postero-lateral 

 Corners subquadrate. Eyes very large, narrowly reniform, with narrow interval 

 at top of head. Antenna 1, 1*** Joint as long as 2^ and 3^ combined, strong, 

 l^t and 2^ serrately carinate below, 3^ serrate, flagellum rather longer than 

 peduncle, joints except 1^* sraall, the alternate distally outdrawn and in ö 

 calceoliferous. Antenna 2 scarcely as long as antenna 1, ultimate Joint of 

 peduncle about ^5 as long as penultimate, flagellum as long as peduncle, similar 

 to flagellum of antenna 1. Gnatbopod 1, lobe of h^^ Joint rounded, 6*^ rather 

 longer than 5*^, broad, palm ill-defined, oblique, convex, finger slender, 

 strongly bent, with dark chitinized point. Gnathopod 2, 6* Joint apparently 

 rather slighter than in gnsithopod 1, palm straighter and rather better defiued. 

 Peraeopod 5 a little longer than peraeopod 4, considerably longer than 

 peraeopod 3, 2*^ Joint with bind margin straighter than in peraeopods 3 and 4. 

 Colour orange- to purple-red. L. 45 mm. 



South-Atlantic (South Georgia).

Body slender, not carinate or dentate. Head scarcely rosti-ate. Side- 

 plates 1 — 4 moderately large. Antenna 1 rather the longer, without accessoiy 

 flagellum. Lower lip without inner lobes. Mandible normal. Maxilla 1, 

 inner plate with several (about 9) setae, outer with spines close-set, outer 

 Corner of 1^* Joint of palp somewhat outdrawn. Maxilla 2, inner plate rather 

 shorter and broader than outer. Maxillipeds well developed, outer plates 

 fringed on inner margin with short spine-teeth, flnger of palp narrow and 

 rather feeble. Gnathopods 1 and 2 subchelate, similar, but 1^* much weaker 

 than 2^. Peraeopods 1 and 2 slender; peraeopods 3 — 5 rather stouter, 

 2*^ Joint not greatly widened, the lower bind corner narrowly rounded. In 

 uropod 1 outer ramus scarcely, in uropod 2 much, in uropod 3 not, shoiier 

 than inner. Telson cleft to the centre.

Head, rosti-um obsolete, lateral corners feebly convex. Side-plates 1 — 3 

 directed slightly forward, rounded below, 4**^ much broader, also rounded 

 below, emarginate behind. Pleon segment 3, postero-lateral corners obtusely 

 quadrate. Eyes large, broadly reniform, narrowly separate above. Antenna 1, 

 1^* Joint rather strong, but not as long as the much narrower 2*^ and 3*^ combined, 

 flagellum considerably longer than peduncle, with 56 joints, the proximal ones, 

 except the 1^*, shorter than broad, alternate joints distally outdrawn. Antenna 2 

 shorter, ultimate and penultimate joints of peduncle subequal, flagellum 

 about 46-jointed. alternately calceoliferous. Mandible, spines of the spine- 

 row are described as short, curved, hyaline, and unfeathered, the palp and 

 also maxilla 1 are said to resemble those of Bovallia gigantea (p. 357 J. Gnatho- 

 pod 1, 5*1» Joint seemingly quadrate, ö*'» oval, palm moderately oblique, defined 

 by an obtuse angle, finger curved, rather shorter than the palm. Gnatho- 

 pod 2, 5*^ Joint cup-shaped but not very short, 6*^ longer, said to be similar 

 in structure to that of gnathopod 1, though very much larger and differently 

 figured, with a much more oblique and less defined palm. Uropods 1 — 3,
