well-developed visual elements, and dark brown ])igmcnt. Superior antennae 

 about tlie lengtli of the cephalon and tlie first 2 segments of mesosome 

 combined, joints of the peduncle successively diminishing in size, flagellum 

 scarcely longer than the peduncle, and composed of about 7 articulations. 

 Inferior antennae a little longer than the superior, last joint of the peduncle 

 somewhat exceeding in length the penultimate one, flagellum rather slender, 

 and nearly as long as the peduncle. Gnathopoda comparatively less feeble 

 than in the other species of the genus, and nearly equal both as to size 

 and structure, propodos in both pairs oblong ova), about the length of the 

 2 preceding joints combined, and provided on the inferior edge with fascicles 

 of spiniform bristles, dactylus of moderate size, and hairy on the inner edge, 

 carpus fully as broad as the propodos, and produced at the end inferiorly 

 to a setiferous lobe, extending in the posterior pair about to the middle of 

 the propodos. Pereiopoda somewhat less slender than in the 2 other species, 

 basal joint of the 3 posterior pairs of moderate size, and oval in form. 

 Last pair of uropoda rather large, reaching beyond the 1st pair, rami naked, 

 and much shorter than the basal part. Telson of moderate size, not 

 extending to the end of the latter, conically tapering, tip tridentate. Colour 

 a more or less dark brown, or blackish violet, from numerous densely 

 crowded pigmentary spots, forming mostly broad transverse bands extending 

 down the coxal plates. Length of adult female scarcely exceeding 3 mm. 



Remarks. — There cannot, I think, be any doubt that the Aniphi- 

 hchus sahrince of Stebbing is this species. As the name given by Boeck 

 is much the older, it must be retained for the present species. It is regarded by 

 that author as the type of the genus Gitann, and may easily be distinguished, 

 when alive, from the other 2 species, by its very dark brownish colour. 



Occurrence. — The species is a sublittoral form, occurring not rarely 

 between algae in shallow water. I have met with it along the whole coast 

 of Norway, from the Christianiafjord to Vads©. 



Disfribntion. — British Isles (Stebbing), coast of France (Chevreux), 

 Kattegat (Meinert), Spitsbergen (Norw. North Atl. Exped.).

Body of a similar short and pulpy form to that in the preceding species. 

 Cephalon scarcely attaining the lengtli of the first 2 segments of mesosome 

 combined, rostrum comparatively shorter than in G. Sarsii, and less strongly
