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



Lindstrrim, including Tlm-mfes guilliamsoniana, Sp. Bate, and Thersifes pelarjica, Sp. Bate, 

 as synonyms, female and male respectively, of Bathyporeia pilosa, Lindstr0m. 



Subfam. in. " Stegocephalinse, Dana 1852," contains Sfef/oce/i/iatos, Kr0yer, with the species 

 Stegocephalus amptiUa, Phipps, and " Stegocephalus Clirisfianensis," n. s. ; Andania, n. g., 

 ■\Tith the new species, Aridania abysd, and Andania nordland.ica. 



Subfam. IV. Amphilochims, contains Amphilochus, Sp. Bate, including, besides the type species, 

 Amphilochus manuidens (more correctly manudens), AmpliUochus odontomjx, n. s., Amplii- 

 lochus hispinosa, n. s., Amphilochus tenuimanus, n. s.; Gitana, n. g., with " Gitana Sajsi," 

 n. s., and Gitana rostrata, n. s.; Astyra ahyssi, n. g. et s. 



Subfam. V. " Phoxinas, Spence Bate 1857," embraces Phoxus, Kr0yer, with the species Phoxus 

 holHlli, Kr., and Phoxus simplex, Spence Bate, 1857, the latter in Sars' opinion being a 

 wrong identification, so that he names Boeck's species Phoxus falcatus on account of the 

 peculiar rostrum ; Harpina (a preoccupied name afterwards changed to Harpinia), a new 

 genus to receive Phoxus plumosus, Kr0yer, and Earpina crenulata, n. s.; Sulcator arena- 

 tins, rather to be called Haustorius armarius. Slabber ; Urothoe, Dana. 



Subfam. VI. Stenothoinoe, new, includes Stmothoe, Dana, Boeck's own Stenothoe danai, being 

 here recognised as a synonym of Montagua marina, Sp. Bate, with the name Stenothoe 

 marina ; Metopa, a new genus to receive Leucothoe clypeata and Leucothoe glacialis of 

 Kr0yer, Montagua alderii, Sp. Bate, Montagua hruzelii, Goes (as to which, Sars, in 1882, 

 points out that Boeck's species is distinct from that of Goes, and he therefore names it 

 Metopa borealis), Metopa affinis, n. s., Metopa longicornis, n. s., Metopa megacheir, n. s., 

 Metopa longimana, n. s., and Metopa nasuta, n. s.; Cressa, a new genus with the new 

 species, " Cressa Schiijidtei" and Cressa minuta. If the species Schiipdiei be, as G. O. Sars 

 considers it, H synonym of Danaia dubia, Spence Bate, the genus Cressa will become a 

 synonym of Danaia, in which Boeck's species minuta, is very doubtfully distinct from its 

 congener. The difficulty with regard to the mandibular palp has been abeady mentioned. 



Subfam. VII. Syrrhoinae, new, receives Syrrhoe, Goes, with the species Syrrhoe cremdata, Goes, 

 and Syrrhoe levis, n. s.; Tiron acanthurus, Lilljeborg ; Brueelia typica, new genus and 

 species. 



Subfam. VIII. Pardaliscinae, new, has Fardalisca, Kr0yer, with the species Pardalisca cuspidata, 

 Kr0yer, Pardalisca boeckii, Malm, and Pardalisca abyssi, n. s.; the new genus Ealice, with 

 the new species Halice abyssi and Halice grandicornis, the latter, according to G. 0. Sars, Ov. 

 Norg. Crust, p. 106, being undoubtedly the male of the former ; Nicippe tumida, Bruzelius. 



Subfam. IX. "Leucothoinae, Dana 1852," includes Lilljeborgia pallida, Sp. Bate, and Lilljeborgia 

 fissicornis, M. Sars, the latter doubtfully distinct from the former ; Eusirus cuspidatus, 

 Kr0yer, and Eusirus longipes, Boeck ; Leucothoe spinicarpa, Abildgaard ; the new genus 

 Tritropis (a preoccupied name), for the species aculeata, Lepechin, " Helleri," n. s., and 

 fragilis. Goes, of which the first two .should perhaps be called Rharhotropis aculeatus, and 

 the third Ehachotropis fragilis. 



Subfam. X. "Oedicerinse, Lilljeborg 1865," contains Oediceros, Kr0yer, with the species saginatus, 

 Kr., lynceus, M. Sars, borealis, n. s.; Acanthostepheia, a new genus to receive "Am.phithonotus 

 Malmgreni," Goes ; Monoculodes, Stimpson, to receive the species Oediceros affinis, Bruzelius, 

 Oediceros norvegicus, Boeck, " Monoculodes Grubei," n. s., Monocidodes loiigicornis, n. s., 

 which in the opinion of J. S. Schneider is very near the preceding Mo7ioculodes grubei, 

 " Monoculodes Kr^yeri," n. s., '^Monoculodes Pacltardi," n. s., Monoculodes tenuirostratus, 

 n. s., Monoculodes tubercidatus, n. s., Monoculodes borealis, n. s., both this and Mmiocidodea 

 norvegicus in Boeck's later work receiving the same synonym, " Oediceros affinis, Goes, 

 Crust. Amphip. maris Spetsb. p. 11. fig. 21 (non Bruzelius)," Oediceros latimanus. Goes; 

 Hnlimedon, a new genus, with the species, " Halimedon M^lleri," n. s. (afterwards spelt 

 Miilleri), " Halimedon Saussurei," n. s. (criticised by J. S. Schneider), Halimedon longimanus,
