the Brit. Mus. Catal., transferred to AUorcheste^ nilssonu,'Rat\ike ; Allorcheistes imhricatus 

 now Hyale x'ontica, Eatlike ; " Galanthis Luhbockiana" which does not differ from Allor- 

 chestes imhricaius ; Montagua marina, now Steiiothoe marina ; " Moniagua Alderii," now 

 Metqpa alderii, aceording to Boeck ; Montagua pollexiana, now Metopa pollmiana, 

 according to G. O. Sars, but see also Note on LUjeborg, 1850; Danaia dubia ; 

 " Lysianassa Audouiniaita," by Boeck referred to Aristias (Arwnyx) tumidus, Kroyer; 

 Lysianassa marina, afterwards referred to Lysianassa atlantica, Milne-Edwards ; Scopelo- 

 cheirus m-enatus, later transferred to CaUisoma crenafa ; Tetroiiiatus typicus, transferred by 

 Spence Bate to Anipelisca gaimardii, Kioyer, by Axel Boeck re-established as an inde- 

 pendent species, Ampelisca typica, Spence Bate, while the species described by Boeck is 

 said by G. 0. Sars to be undoubtedly the male of Ampelisca temdcornis, Lilljeborg, with 

 which again Bate's species does not agree. Hoek, Carciu. p. 145-6, decides for calling 

 it Ampelisca carinata, which (with Norman) he supposes to be the male of Ampelisca 

 eequieornis, Bruzelius ; " Tetromatus Bellianus," transferred by Spence Bate to Ampelisca 

 helUana, by A. Boeck to Ampelisca Ixvigata, Lilljeborg ; Westwoodia ccecula, afterwards 

 changed to Westwoodilla ccecula; Kroyera carinata, changed to Monoculodes carinatiis ; 

 " Phoxiis Kroyerii," transferred to Phoxus simplex, Spence Bate ; " Phoxus Holbolli," after- 

 wards recognised as Kroyer's species of the same name ; Sulcator marinus, later transferred to 

 Urotho'e marirais ; Darwinia compressa, identified by Boeck with Laphystius sturionis, 

 Kroyer; " Acanthonotus Owenii," afterwards referred to Acantlwnotus {Oniscus) testtulo, 

 Montagu, then reinstated as Acanthonotus oicenii, and finally, Brit. Sess. Crust., vol. ii. 

 p. 528, referred to Epimeria (Gammanis) cwnigera, Fabricius; Dexamine bispinosa, placed 

 by Boeck in his genus Halirages ; "Dexamine Oordoniana," afterwards recognised as a 

 synonym of Atylus (Amphitoe) swammerdamii, MUne-Edwards ; " Ccdliope Leachii," later 

 referred to Ccdliopius {Amptliitlioe) Ixviusculus, Kroyer ; " Lembos Camh-iensis," transferred 

 to Microdeutopvs (Gammarus) anomalus, Rathke ; Lembos verdeidatus, transferred by Spence 

 Bate to the genus Microdeutopus, by Boeck thought probably to belong to Autonoe ; 

 " Lemhos Damnoniensis," later recognised as synonymous with Alicrodeutopiis gryllotalpa, 

 Costa; Lonchomerus gracilis, later placed in Kroyer's genus Aora, as Aora gracilis; 

 Eurystheus tridentatus, later seen to be a synonym of Gammarus erijtlirophthcdmus, 

 Liljeborg, and by Boeck therefore named Gammaropsis erythrophthahnus, though he 

 seems, according to G. O. Sars, to have confused with it a different species ; Gammarella 

 orchcstiformis, later found to be synonymous with Gammarella {Gammarus) brevicaudata, 

 MLbie-Edwards ; Gammarus inseqidmanus, subsequently found to be a synonym of Melita 

 (Cancer Gammarus) pialmata, Montagu; Gammarus ? pallidus, afterwards placed in anew 

 genus as Liljeborgia pallida ; UrotJwe elegans, stated scarcely to differ from Urotho'e 

 irrostratus of Dana, but separated from it because forms from the Sooloo Sea can scarcely 

 be supposed to belong to the same species as British forms — an unsafe ground of distinc- 

 tion ; " Thersites Guilliamsoniana" afterwards found to be a synonym of Bathyporeia pilosa, 

 Lindstrom ; Thersites pelagica, the (? of the preceding species ; Leucothoe procera, subse- 

 quently made a synonym oi LeucotJioe {Lycesta) furina, Savigny; " Pleonexes Gammaroides," 

 later named Ampihitoc gammaroides, and probably belonging to the division that has been 

 named Sunamphithoe, the Anisopus of Templeton ; Amphithoe littorina, referred by Boeck 

 to Amphithoe podocm-oides, Eathke, probably the same as Amphithoe rubricata, Montagu ; 

 Sunampihitoe hamulus; Sunamphitoe conforinata, probably the male of the preceding 

 species; (in this and the preceding genus the spelling -thoe was afterwards adopted for 

 the termination of the names) ; " Cyrtophium Daru-inii," better named Platophium 

 darwinii ; Ericthonius difformis, here entered without name of any author for the 

 species, but afterwards in the Brit. Mus. Catal. distinguished from Erichthonius difformis, 

 Milne-Edwards, and made .synonymous with Cerap)us abditus, Templeton; " Siphonocetu
