ultimate Joint of peduncle rather longer than penultiraate, flagelluni nearly a» 

 long as peduncle. Gnatbopods 1 and 2 less feeble thau in the other 2 species;. 

 6*^ Joint in guathopod 1 with front margin shorter than 6*'\ produced 

 setiferous bind margin equal to it; 5*^ Joint in gnatbopod 2 witb front margin 

 shorter, but produced setiferous bind margin mucb longer than 6*^, which 

 in botb is narrowly oval, with fascicles of spiuules on bind margin, ünger 

 rather small, birsute on inner margin. Peraeopods 1 — 5 not quite so sleuder 

 as in the other species, 2*^ Joint in 3*^ — b^^ paii-s oval, üropod 3 reaching 

 beyond uropod 1, peduncle mucb longer than unarmed rami. Telson not 

 reaching apex of peduncle of uropod 3, tapering to tridentate apex. Colour 

 dark brown or blackisb violet, the crowded spots usually in transverse bands.

Body Short and stout. Head, rostrum shorter and less strougly curved 

 than in G. sarsi (p. 155), lateral corners rather more produced. Side-plate 2 with 

 only 2 serrations on the obtusely pointed tip, 4*^ quite smooth. Pleon 

 Segment 3, postero-lateral angles less produced. Eyes larger, rounder, less

 antenna 2 comparatively shorter, 6-jointed. Gnatbopod 1, 5^^ Joint little 

 produced, little longer than 6*^; gnatbopod 2 longer and more slender than 

 gnatbopod 1, 5*^ Joint more but still not greatly produced, on botb margins 

 mucb longer than 6*^ Joint. Peraeopods 1 — 5 more slender, 2*^ Joint of

Body less stout. Head, rostrum slightly curved, more produced, acuminate, 

 lateral corners rounded, little produced. Side-plate 2 comparatively much 

 larger, all the narrowly rounded distal margin serrate, 4*'' seemingly a little 

 serrate. Pleon segment 3, postero-lateral angles slightly produced. Eyes 

 small, rounded, feebly developed, light red with whitish coating. Antenna 1, 

 2^ Joint of peduncle longer than 1***, flagellum shorter than peduncle, 7-jointed. 

 Antenna 2 much longer than antenna 1, ultimate and penultimate joints of 

 peduncle subequal. flagellum about half lengtb of peduncle. Gnatbopods 1 and 2 

 very slender and feeble, 5*^ Joint scarcely at all produced on setose bind margin, 

 much longer than almost linear 6*^; gnatbopod 2 rather longer than gnatbo- 

 pod 1. Peraeopods 1 — 5 very long and slender, 2*^ Joint of 3*^ — 5^^^ paii'S 

 large and laminar. Uropod 3 rather long, but scarcely reaching beyond 

 uropod 1, peduncle mucb longer than the unarmed rami. Telson not reaching 

 apex of peduncle of uropod 3, tapering to a simple apex. Colour whitish, 

 without spots, sometimes faintly tinged witb red. L. 9 7 mm.
