REPORT ON THE AMPHIPODA. 287 



sexti pai'is forma singulari : pars basalis duplo longior quam latior ; ramus finalis interior 

 rudimentarius et forma folii acuminati ; ramus exterior magnus, biarticulatus ; articulo 

 primo lamelloso, parte basali ter longiore ; articulo secunclo parvo, acuminato, setis 

 instructo." 



Tho type species is described under the name Bathyporeia pilosa, and figured Tab. ii. figs. 1-11. 



Po7itoporeia afflnis, n. sp., is thus described : — " OcuU nigri, elongati. Antennae inferiores 

 superioribus longiores ; antennce superiores flagello appendiculari triarticulato. Annulus 

 abdominaHs quintus setis ilUs, quas habet P. femorata, carens. Partes femorales pedum, 

 ut etiam epimera, ornatse textura singulari cellulosa, quse globulis adiposis forma ta est." 

 It is figured Tab. ii. figs. 1-4. Lindstrom comments on the relationship of his species to 

 the Arctic Pontoporda femorata, to which, in the fuller description, he recognises it 

 as coming very close. It was the only Amjjhipod he found at 40 fathoms, the greatest 

 depth his dredging reached. Subsequently, he seems to have given up its specific 

 distinctness. See Note on Mobius, 1873. Gammarus locusta, he says, may be found 

 wherever sea-weed grows. He notes too, that there are certain forms of Crustacea which 

 can stand great variations in the saltness of the water they inhabit. He mentions also 

 Amphitoe rathkii, Zaddach, and GoropMum longicmme, Latr.

This paper is intended to show that the English well-shrimp, which Schiodte named Niphargus 

 aquilex, is distinct from his Nipliarcjus stygius, out of the caverns of Adelsberg and Lueg in 

 Carniola. Bate and "VVestwood, i. 317, say that Schirtdte has been misled into describing 

 Niphargus aquilex with " dorso carinato," by examining dried specimens, but on other 

 grounds they incline to agree with his discrimination of the two species in question.

The Amphipoda of this paper include Phoxvs geniculatus and Phoxus obtusus, both, in Loeck's 

 opinion, insufficiently described for identification. The three-jointed outer ramus of the 

 last uropod in Phuxus geniculatus probably only indicates a two-jointed ramus with a 

 terminal spine. Derccthoo? producius is another among the many riddles presented by
