]96 THE VOYAGE OF H.M.S. CHALLENGER. 



Subfam. XVI. Leptocheirinse, new, contains Leptocheirus pilosus, Zaddach, and tlie new genus 

 Goeda, for Autonoe depressa, Goes. 



SuLfani. XVII. Photins, new, said by a slip, which is repeated in the larger work, to have 

 " Pedes 7mi paris breviores quam 6ti paris," receives Photis reinhardi, Kr0yer, " Photis 

 Liitkeni," n. s., which Norman identifies with the earlier Eiscladus longicaudatus. Bate and 

 Westwood, while Boeck makes longicaudatus a synonym of Eeinhardi ; Mieropi'otopus 

 macidatiis, Norman ; " Xenoclea Batei," a new genus and species, which is so like the 

 earlier Nxnia rimapalma of Spence Bate, that I do not think they should be kept distinct, 

 although Boeck says that the apex of the telson in his species is cleft or sinuate. On the 

 other hand the genus Nmiia, 1862, must yield to Podoceropsis, 1860. 



Subfam. XVIII. Microdeutopinse, new, contains Microdeutopus, Costa, 1853, for the species 

 Microdeutopus gryllotalpa, Costa, and Gammarus anomaliis, Eathke ; Aora gracilis, Sp. 

 Bate; Autonoe, Bruzelius, 1859, for Gammarus longipes, Lilljeborg, and Autonoe pilumosa, 

 n. s.; Protomedeia fasciata, Kr0yer, and Protomedeia longimana, n. s.; Gammaropsis 

 erythrophthalmus, Lilljeborg, the species described by Boeck being, according to G. 0. Sars, 

 Ov. Norg. Crust., p. Ill, quite distinct from Lilljeborg's, on which account he renames it 

 Gammaropsis melanops, although it must be observed that in this work the eyes are said 

 to be " rubri," an expression omitted from the later work, where no coloiir for the eyes is 

 mentioned ; Podoceropsis sopliiee, Boeck. 



Subfani. XIX. Amphithoinae, new, contains Amphithoe podoceroides, Eathke, Amphithoe 

 grandimana, Boeck ; Sunamphithoe hamulus, Sp. Bate, Sunamphitlwe longicornis, n. s. 



Subfam. XX. Podocerinas, new, includes Podocerus, Leach, to receive Ischyrocenis latipes, 

 Kr0yer, Podocerus megaclieir, n. s., Ischyrocenis anguipes, Krpyer, Cancer (Gammarus) 

 falcatus, Montagu ; Janassa, a new genus for Podocerus variegatus. Leach, which is 

 probably only a form of Podocerus falcatus, while the name Janassa is preoccupied among 

 fo.ssil fish; Cerapus, Say, 1817, to receive Cerapus abditus, Templeton, Cerapus difformis, 

 IMilne-Edwards, Cerapus longimarms, n. s., and Cerapus hunteri, Sp. Bate, the last three of 

 which S. I. Smith places in the genus I<Jrichtho7iius, Milne-Edwards, making the species 

 hunteri synonymous with difformis. 



Subfam. XXI. " Chelurinae,. Allman 1837," has only Clielura terehrans, Philippi. 



Subfam. XXII. " Corophinse. Dana 1849," contains Corophium, Latreille, 1807, to receive Cancer 

 grossipes, Linn^, CwopMum crassicorne, Bruzelius, 1859, with "? Corophium acherusicum, 

 Costa," 1856, and "'! Corophium crassicorne (Bruzelius), Spence Bate and Westwood," 

 1863, given in the synonymy, Corop)hium affine, Bruzelius, with "? Corophium Bonellii, 

 Milne-Edwards," 5 , 1830, in the synonymy, this last being, according to G. 0. Sars, Ov. 

 Norg. Crust., p. 112, distinct from Corophium crassicorne, Bruzelius, to which Boeck in 

 his later work doubtfully makes it a synonym, withdrawing it from Corophium affine ; 

 Siphonoecetus, afterwards corrected to Siphonoecetes, Kr0yer, 1845, to receive Siphonceeetes 

 typicus, Kr0yer, "Siphonoecetes Colletti," n. s.; Glauconome, Kr0yer, 1845, a preoccupied 

 name, which must yield, as pointed out by S. I. Smith, to Unciola, Say, but here used 

 for the three species, leucopis, Kr0yer, which Smith identifies with Unciola irrorata, Say, 

 " Kr^yeri,^' n. s., and " Steenstrupi,'' n. s.; and lastly Hela (now Neohela) monstrosa, Boeck. 



Fam. IV. "Dulichidie. Dana 1849," comprises Didichia, Kr0yer, 1845, with six species, 

 spinosissima, Kr0yer, falcata, Sp. Bate, " Nordlandica," n. s., tuberculata, n. s., curticauda, 

 n. s., porrecta, Sp. Bate; Paradulichia typica, new genus and species; Lxtmatophilus, 

 Bruzelius, 1859, with the species tuberculatus, Bruzelius, and spinosissimus, n. s.; 

 " Xeiiodice Frauenfeldti," new genus and species. 



Fam. V. " CapreUidai. Leach 1815," has two subfamilies: — 



Subfam I. CapreUinse, new, contains Proto goodsirii, Sp. Bate, which is now made a synonym of 

 the following species, Proto ventricosa, Miiller ; Oercops holb^i, Kr0yer ; .^Egina, Kr0yer,
