Report on the Crustacea collected by the Naturalists of the Arctic Expedition 

 in 1875-76. The Annals and Magazine of Natural History. Number CXV. pp. 

 52-66. Number CX VI. pp. 96-110. Vol. XX. Fourth Series. London, 1877. 



The account of tlie Crustacea " is confined to the species collected between lat. 78" and 84° N." 

 " The most northerly species collected is Arinnijx migax, one of the commonest and most 

 abundantly distributed of the Arctic Amphipoda, and first made known to science a 

 hundred years ago by Phipps." At page 56 a table is given of "the Geographical 

 distribution of the Crustacea collected by the Arctic Expedition north of lat. 78° N." This 

 includes 1 2 species of Amphipoda, common to Greenland and Spitzhergen, 9 of them being 

 also Scandinavian, 5 or 6 of them belonging to Arctic America, 3 to Iceland, 4 to Britain, 2 to 

 north-east Asia. A species of Amphipod, "perhaps belonging to the genus Pherusa," is men- 

 tioned as having been collected by A. C. Horner, Esq., while on board the yacht "Pandora," 



On Anonyx nugax, Phipps (Anomjx lagena of Sp. Bate, Boeck and Buchholz), Miers says, " my 

 observations scarcely agree with those of Hr. Buchholz and other authors as regards the rare 

 occurrence of the males of this very common and well-known Amphipod." The far longer 

 flagella of the inferior antennae distinguish the males. The largest male taken measured 

 li inch, the largest female 1 inch 9 lines. 



For " Anoni/x gvlnms ? PI. III. fig. 2," the synonymy gives Anonyx gulosus, Kroyer, Sp. Bate, 

 and Boeck ; Anonyx norveginis, Lilljeborg, and "? Anonyx Iwlhiilli, Sp. Bate, Brit. Mus. 

 Catal., p. 75. The description is followed by these remarks, " I have referred the 

 specimens collected by Mr. Hart with some doubt to the Anonyx gulosus of Kroyer, as the 

 antero-lateral margin of the head is less broadly rounded, and the accessory flagellum is 

 longer than that of A. gulosus according to Boeck's diagnosis. In the form of the first and 

 second pairs of legs and of the terminal segment they agree well with the descriptions of 

 A. gulosus, and particularly in the presence of a tooth on the inner margin of the dactyl, 

 which is mentioned by Lilljeborg as characteristic of that species. From A. pumilus they 

 difier in the shorter antennse, and in the absence of a tooth on the posterior margin of the 

 fifth postabdominal segments." 



" Oiiesimus Edicardsii. I'l. III. fig. 3," has for synonymy, "Anonyx Edtcardsii, Kroyer," 

 " Lysianassa Edwardsii, Goes," and " Onesimus Edwardsii, Boeck." After the description, 

 Miers says, " the specimens collected differ from Boeck's diagnosis in one particular, the third 

 segment of the postabdomen is slightly produced upwards at the postero-lateral angle. 

 Nothing is said of the form of this segment by Kroyer in his description of the species or in 

 the Latin diagnosis that follows. In Kroyer's figure of the species in the Atlas of the 

 ' Voyage en Scandinavie,' the postero-lateral angle of this segment is represented as not 

 produced upward, but acute. There is, however, a manifest inconsistency between the 

 diagnosis of Boeck and the figures in the Atlas referred to ; e.g., in OnesimMS j^lautus the 

 third postabdominal .segment is described by Boeck as ' sursum productus acutus,' but 

 figured by Kroyer as broadly obtuse and rounded at the postero-lateral angle. Onesimus 

 edicardsii has been recorded from Greenland, Spitzbergen, and Britain." 



Notes are given upon Atylus carinatus, Fabr. To Araniho:xmc hyslrix is attached the synonymy, 

 Acanthosoma hystrix, Owen and Ross, Bell; Ampliithoe hystrix, Kroyer, M.-Edw. ; 

 Paramphithoe hystrix, 'Rvaz&Wus, Sp. Bate; Acanthosone eusjn data, 'Boeck, nee 'Le'pechm ; 

 Aranthozone hystrix, Miers, Ann. and Mag. Nat. Hist. (ser. 4) xix. p. 137 (1877); with 

 the remark, " in the elaborate plate that illustrates this species in the ' Zweite deutsche 

 Nordpolarf.' [1874], the rostral spine is represented as conical, straight, and acute, and the 

 basos joint of the sixth and seventh pairs of legs as armed with four strong spines upon its
