REPORT ON THE AMPHIPODA. H35 



Station 149e, Greenland Harbour, Kerguelen Island, January 21, 1874; depth, 30 

 fathoms ; bottom, volcanic mud. One specimen. Dredged. 



Remarks. — There is the possibility, as I have elsewhere suggested, that these creatures 

 may have travelled out from our own waters along with the vessel to the southern lati- 

 tudes at which they were captured.

Upper Antenna. — The third joint of the peduncle longer than the first, shorter than 

 the second ; the flagellum much more slender than the peduncle, of six joints, together 

 scarcely longer than the second of the peduncle, the first much longer than any of the 

 others, the second not completely separated from the first ; the secondary flagellum 

 slender, scarcely half the length of the first joint of the primary, two-jointed, but the 

 second joint minute, tipped with setules as long as the secondary flagellum itself. 



Lower Antenna. — Peduncle stout ; the flagellum also stout except the small 

 fourth joint at the apex, the four joints together as long as the fourth joint of the 

 peduncle, the first joint being much longer than the other three together, bordered with 

 many spines, both slender and short stout curved ones, the remaining joints having 

 similar armature apically. 



Mandibles. — The cutting edge with four or five teeth on the left mandible, with five 

 on the right, of which the lowest but one is conspicuously the largest ; the secondary 

 plate with four teeth on the left mandible, on the right mandible with one tooth and a 

 denticulate border above it not cut into actual teeth ; the spine-row with three broad 

 spines (serrate on the outer edge) on the left mandible, and two such on the right 

 mandible. The molar tubercle powerful, very similar to that described for Podocerus 

 falcatus ; the first joint of the palp short, widening distally ; the second joint broad, 

 at first widening, but narrowing at the distal part, carrying many spines on and near the 

 irregular front margin ; the third joint shorter than the second, from a very narrow neck 

 widening rapidly, along the distal half of the inner margin and round the broad apex 

 carrying many unequal, long and broad, slightly feathered, more or less curved 

 spines. 



Maxillipeds. — The inner and outer plates not very different from those of Podocerus 

 falcatus ; the palp broad, the first joint almost triangular, reaching beyond the inner 

 plates, the second joint not twice as long as the first, with many slender spines about 

 the inner and apical margins, and the inner apex having two that are very long ; the
