436 THE VOYAGE OF H.M.S. CHALLENGER. 



submerged woodwork six Ainphipoda are mentioned, p. 98 (392), among wldcli it is 

 curious to note that Chelura terehrcms is nut included. Of Amphipods ordinarily found 

 on the bottoms of the bays and sounds, he enumerates for those that are rocky, p. 115 

 (409), nine species; for those that are gravelly and shelly, p. 128 (422), seven species; 

 for those that arc sandy, p. 134 (428), two species, Leimlactylis dytisms being included in 

 this and the two preceding lists; lastly, for those that are muddy, p. 140 (434), "several 

 species " of Lysianassinse, and eight of genera in other families. 



In the section on " free-swimming and surface animals," he says, " several species of Amphipods 

 are also common at the surface. The most abundant were Callinpius Ixniiscuhis, of 

 which Mr. V. N. Edwards also took numerous large specimens in February and March ; 

 Gammarus natator, which was usually common, and occurred in immense numbers 

 August 10 and on several other occasions ; and a Hjiperia, which infests several species 

 of large jelly-fishes, and also swims free at will. The Plironinia is a related genus, but is 

 very remarkable for its extreme transparency, which renders it almost invisible in water." 

 The list, p. 158 (452), mentions "several species" of Lysianassinee, and eleven species of 

 genera in other families. 



At p. 163 (457), he says, "among the Crustacea there are a few species of Amphipods that are 

 l^arasitic. One of these, Lapln/stius siurionii^, lives upon the gills of fishes and upon the 

 surface of the body. It was found on the gills of the "goose-fish" (Lopliius), in Vineyard 

 Sound, and on the back of skates at Eastport." In the list of external parasites, he 

 mentions, besides Laplnjiifius durwnis, " Hyperia, sijeuies, on jelly-fishes." 



On the sandy shores and bottoms of estuaries, three Amphipods are recorded, p. 170 (464); 

 on the muddy shores and bottoms of brackish waters, eight species, p. 177 (471); on 

 oyster beds in brackish waters, four species, p. 182 (476); among eel-grass in brackish 

 waters, eight species, p. 186 (480); on piles, etc., in brackish waters, four speyes, p. 188 

 (482); on outer rocky shores, nine species, p. 193 (487); on sandy shores of the open 

 coast, four species, p. 196 (490); on the stony and rocky bottoms on the open coast, nine 

 species, or more, since he says, "species of Caprella occur in considerable numbers," 

 p. 200-204 (494-498); on sandy and gravelly bottoms off the open coast, eight species, 

 p. 210 (504); on soft mud and sandy mud off the outer coast, seven species, p. 217 

 (511). 



In the "lists of species found in the stomachs of fishes," pp. 220-227 (514-521), he mentions 

 "Scup; Forgek; (Sfeyiohmuif- airiyropx.) Forty young specimens, one year old, taken at 

 Wood's Hole in August, contained large numbers of Amphipod Crustacea, among which 

 •were Unciola in-orafa, Ampelisra, s-p., etc." "Haddock; {MeJanogrammiig ecglifinus.) . . . . 

 A specimen taken at Wood's Hole, November 6, 1872, contained a large quantity of Gam- 

 marus natator." "Tom-Cod; Fkost-Fish; (Microgadus tom-codus.) Several specimens 

 from New Haven Harbor, January 30, contained numerous Amphipods, among which were 

 Mwra levis ; Gammarus, sp.; Ampelisca, sp.;" others at Wood's Hole, in March, contained 

 " large quantities of Amphipods, especially of Gamraarus animdatus, G. 7iatator, Calliopius 

 Ixviusc.ula, and Microdeufopus mina.i:; and smaller numbers of Gammarus ornatus and 

 G. mucronatus. Another lot of twelve, taken in April at the same place, contained most 

 of the above, and in addition several other Amphipods, viz., Mwra levis, Pontogeneia 

 inermis, PHloclieirus pinguis, and Caprella." " Ocellated Flounder; Summer 

 Flounder; {Chxtiopsetta ocellaris.) . . contained . . . Amphipod Crustacea belonging to 

 the genus Aiiipelisca." "Spotted Flounder; {Loplwpseifa mandata.) . . contained 

 . . . numerous Amphipods, Gammarus mucronatus." Sea-Herring; (Clupea elongata.) 

 . . contained . . . large numbers of an Amphipod, Gammarus 7iatato7\" 



The Systematic Catalogue of the Amphipoda inhabiting the coast between Cape Cod and New 

 York, drawn up by Mr. S. L Smith, occupies pages 261-273 (555-567). It includes
