434 THE VOYAGE OF H.M.S. CHALLENaEU. 



perhaps rather the rightful name, and from which Professor Smith says that his species, 

 though differing only in minor details, is undoubtedly entitled to be considered distinct. 

 Very large specimens had been obtained in Colorado, from an elevation of 9000 feet. 

 He next describes Gammarus fasciatus, Say. Of Gammarus minus, Say, he remarks that 

 he has " not yet been able to rediscover this species, which is very likely not a true Gam- 

 marus.'" The Gammarus ininus of De Kay, he says, " is made up principally of Say's 

 original description," with a " rude attempt at a figure " apparently from some other species, 

 probably Gammarus fasciatus. He describes both sexes of Crangonyx gracilis, Smith, 1871, 

 and mentions Grangonyx vitreus, Packard, 1873, giving under protest as a synonym, 

 " ?? Styguhromus vitreus Cope, American Naturalist, vol. vi, p. 422, 1872 ; Third and Fourtli 

 Annual Eeports of the Geological Survey of Indiana, p. ISl, 1872." He describes 

 Grangonyx tenuis, n. s., " a slender, elongated species, with very low epimera, resembling 

 more in form the species of Niphargus than the typical species of Grangonyx." 



In the " Sketch of the Invertebrate Fauna of Lake Superior," four Amphipoda are mentioned, 

 Hyalella clentaia, " Pontoporeia Hoyi," Gammarus limnseus, Grangonyx gracilis, with refer- 

 ences to the descriptions already given. 



In the Section on the " Food of Fresh-water Fishes," " Pontoporeia Hoyi," is mentioned as found 

 in the stomach of the White-fish {Coregonus alhus), at various stations.

" Liljeliorgia Normanni " is described and figured as a new species, near to Liljehorgia 

 shetlandica. Bate and Westwood, both species being synonyms of Cheirocratus sundevalli, 

 Eathke. A variety of Iphimedia ehlanse is described and figured, as intermediate between 

 that species and Iphimedia ol/esa, with the suggestion that distinction implied by the two 

 specific names may, in fact, be one of sex. The male of Mierodeutopus versiculatus, 

 Sp. Bate, is figured and discussed. This species, in Boeck's opinion, may be the same 

 as Autonoe longipes, Lilljeborg, but the first gnathopods do not suit that view. The 

 alteration of 3Iicrodeufopus to Microdeiiterojnts, accejited in this paper, I no longer think 

 necessary. Micropirotoptus macidatus, Norman, is figured, and some notes are given on that 

 species. Gammarella bi-evicaudata, ?, Milne-Edwards, is figured and discussed to show 

 that " Gammarella Normanni," Bate and Westwood, is in fact the female of Milne- 

 Edwards' species. This had been abeady suggested by Mr. Spence Bate in the Brit. 

 Mus. Catal., p. 379.

AmpMtlwe ctmiculus, n. sp., is described and figured. Amphitlwe ruhricata, Montagu, is 

 compared with AmpMtlioe littorina, Sp. Bate, and the inference drawn that they are 

 varieties only of the same species. Amp)lrithoe littorina is by Boeck identified with 

 Amphitlwe pjodoceroides, Eathke, but Montagu's name being still older will take
