REPORT ON THE AMPHIPODA. 1645 



subchelate, the hand not longer than the wrist; in the first and second perseopods the 

 fourth joint is much shorter than the third ; the third peraeopods are longer than the 

 fourth, and the fourth than the fifth ; in the fifth the first joint is very large and the third 

 and fourth joints are strongly plumose ; the telson is rather longer than broad, cleft almost 

 to the base. The name of the type-species is variously given as Nordenskibldii, Norden- 

 skipldii, and Nordenskjoldii. 



To Hyperia latreillei, Milne-Edwards, the synonyms given are Lestrigonus exulans, Kr0yer, 

 11 Hyperia obi 'icia, Kr0yer, 11 Hyperia medusarum, Boeck, 11 Hyperia latreillei, Bovallius, 

 1? Parathemisto oblivia, Bovallius ; to " Hyperoche medusarum (Kr0yer) " the synonyms 

 are Metoecus medusarum, Kr0yer, . Tauria medusarum, Boeck, " Hyperoche Kroeyeri," 

 Bovallius, " Hyperoche Luetkeni," Bovallius ; Parathemisto compressa, Boeck, and Themisto 

 bispinosa, Boeck, are both assigned to Euthemisto compressa (Goes) ; " Euthemisto Norden- 

 skioldi," Bovallius, is made one of the synonyms of Euthemisto libellula (Mandt) ; 

 Hippomedon dentiadatus (Sp. Bate) (Tab. II. figs. 2-26) is separated from Hippomedon 

 HolHUi (Kr0yer) ; on " Aristias tumidus (Kr. non aut.) (Tab. II. figs. 3-36)," the remark 

 is made, " Anonyx (Aristias) tumidus aut. cet. (Bruzelius, Boeck, Lilljeborg, Heller) non ad 

 speciem a Kroyer descriptam referendus est. Speciem ab autoribus descriptam Arist. 

 neglectum appello.) " (Tab. II. fig. 4) ; on Amphilochus concimms, Stebbing, the remark is 

 made " (Amph. manudens Boeck non ad Amph. manudens Sp. Bate referendus est)," while 

 the identity of Amphilochus manudens, Boeck, with Amphilochus cancinnus, Stebbing, is 

 thought possible but a little doubtful ; " 1 Metopa borealis G. O. Sars " (Tab. III. figs. 4, 4a) is 

 7 mm. long in contrast with the 3 mm. of Sars' specimen ; on Metopa longimana, Boeck, 

 (Tab. III. figs. 8-86), it is observed that in Boeck's work, PI. XVII. fig. 5 does not belong 

 to this species, and PL XVIII. fig. 3 probably does not ; Metopa nasuta, Boeck, is given 

 with a query, since the Greenland specimens differ by elongate fourth segment of the person 

 and the slightly carinate back ; under Monoculodes crassirostris, n. sp., a discussion is given 

 onMonoculod.es affinis and someother speciesof that difficult genus; to Paramphithoepulchella 

 (Kr.), " 1 Paramphitlwe euacantha G. 0. Sars" is given as a synonym ; of " Melita Goe'sii 

 H. J. Hansen" (Tab. V. fig. 8) the second gnathopod is figured; " AmathiUa arenaria 

 (0. Fabr.) " is a new name for AmathiUa sabini (Leach), this species being identified with 

 Oniscus arenarius, O. Fabricius, 1780, but the name AmathiUa homari will take precedence 

 for the reasons given in the Note on J. C. Fabricius, 1779 (p. 45) ; see also Note on 

 O. Fabricius, 1780 (p. 47). On " Euthemisto compressa," see p. 1409. 



In the " Kort Oversigt over de af 0. Fabricius i ' Fauna Groenl.mdica, 1 780 ' onitalte bojere 

 Krebsdyr," pp. 223-226, Dr. Hansen says that the reference of Caprella septentrionalis, 

 Kroyer, to Squilla lobata, Miiller, may be regarded as well grounded ; that " Oniscus 

 Medusarum (Mull.)" is certainly the same as "Hyperia Latreillei M. Edw. " ; that 

 " Oniscus Cicada O. Fabr." is perhaps, as Kr0yer supposes, the same as " Anonyx 

 gulosus Kr.," but more probably, the greedy " Onisimus Edwardsii (Kr.)," so common 

 in Greenland ; that " Oniscus arenarius, 0. Fabr." is certainly the same as " AmathiUa 

 Sabini (Leach)," on which see above ; that " Oniscus Stroemianus 0. Fabr." may he an 

 Orchestia, probably Orchestia litorea (Mont.), but that, since no Orchestid appears to 

 have been since found in Greenland, the whole matter is doubtful; that "Oniscus 

 abyssinus O. Fabr." partly suits Pontogeneia inermis (Kr.), and partly CaUiopius 

 Iseviusculus (Kr.), but neither of these entirely, nor yet any other species known from 

 Greenland ; and lastly, that " Oniscqs serratus O. Fabr." is as already suggested by 

 Kr0yer the same as Acanthonotosoma serratum (0. Fabr.).
