REPORT ON THE AMPHIPODA. 445 



V. Zoologisclie Ergehnisse dcr Norclseefahrt.. X. Crustaceen aus den 

 Ordiiungen Edriophtlialmata und Podophthalmata. Bearbeitet von Prof. Dr. A. 

 Metzger in JMlinden. Hiezu Abbildungen auf Kupfertafel VI. pp. 277-310. 



A list of Ampliipoda is given, pages 278 to 284, numbering eightj-tliroe species, with particulars 

 as to place of capture, depth, nature of ground and geographical distribution. Species 

 previously taken by Leuckart or by Metzger himself, even if not observed on the present 

 exi^edition, are included. On Ampliithoe gibba, E. Leuckart, the note is given, "Von 

 spiiteren Forschern uicht wieder aufgefunden, oder docli nicht erkannt. Die 1. c. [Frey und 

 Leuckart, Beitriige p. 162] gegebcne Beschreibung ist zu unvollstiindig. Nach der 

 Uebereinstimmung mit A. Eathkei zu urtheilen, gehort die Art wahrscbeinlich der Gattung 

 Calliopius an." See Note on Frey and Leuckart, 1847. Of Gammarus eJongatus, 

 Leuckart, he says, " Spiiter, wis es scheint, noch nicht wieder aufgefunden." He notices 

 Boeck's opinion that it may be Ma:ra longimana, Thompson. He here gives Knnjera 

 arenaria, Bate, with Boeck's Pontoerates norvegicus as a synonym. 



Fuller notes and descriptions of new species are given on pages 296-300. Dulichia wonacanilia, 

 n. s.. Tab. vi. fig. 8, is thus described : — 



" Caput antice paulum productura et rotundatum. Epimerum primum in spinam longam 

 jiroductum, epimerum secundum margine posteriore rotundato, marginc interiore recto et 

 parum modo producto. Pedes secundi paris manu longiore quam latiore, dontibus duobus 

 instructa, dente postico longiore et acuminato. Pedes quinti et sexti paris articulo tertio 

 longitudinem quarti et quinti junctorum vix superanti. Pedes septimi paris articulo quarto 

 longiore quam quinto, articulo tertio prajlongato, longiore quam primo. Pedes saltatorii 

 ultimi paris pedunculo vix dimidiam longitudinem rami interioris aequanti. Longitudo 

 animalis c. 5 mm." It comes, he says, very near to Dulichia porrecta. Of another 

 Duh'rJiia, spec, dubia, he had only a single defective specimen, a female with eggs. This 

 he describes, as also the female of Hela mmtrosa, Boeck, in which his two specimens 

 .showed the first gnathopods larger than the second, having the hand curved, not with three, 

 but only two teeth. He describes the tubes of Slphomxeetes cuspidalus, Metzger, as 

 apparently very fragile. 



BgbHii crass^icornis, n. s., Tab. vi. fig. 9 is thus described : — 



" Femina. Corporis forma angustior, antennne vero robustiores quam in B. Gaimardi ; 

 segmentum postabdominis quartum in anteriore parte paulum transverso impressum, postice 

 obtuso carinatum ; segmentum postabdominis tertium in angulo inferiore posteriore 

 rotundatum. Caput inter antennas superiores parum productum. Antennae superiores 

 inferioribus baud multum breviore.s, articulo pedunculo secundo pralongato, ter longiore 

 quam primo. Antennae inferiores articulo quarto parum longiore quam quinto. Pedes 

 primi paris manu paulum breviore quam carpo ; jjedes secundi paris manu multo breviore 

 quam carpo angusto. Pedes tertii et quarti paris ungue tam longo quam articulo quinto. 

 Pedes quinti paris articulo jirimo altiore quam lato, ovali, iu margine posteriore lobo lato 

 semiorbiculari instructo. Pedes sexti paris articulo primo marginibus fere rectis. I'edes 

 septimi paris articulo primo ad marginem inferiorem articuli tertii deorsum et postice 

 productum, articulo quinto lineari, vix breviore quam quarto, ungue styliforme paulo 

 breviore quam articulo quinto. Appendix caudalis parum longior quam ad basin lata, 

 postice angustior et rotundata in summo dimidio fissa, lacinia utraque in superficie spinis 

 singulis armata. Longitudo corporis 8mm. — Habitat extra oras Norvegi;e Jsederenses in 

 profunditate 106 orgyarum." 



On " Ampelisca Esrhriditi," Kroyer, he notes some difJerences fiom Boeck's account. For his 

 criticism of the description and figures assigned by Buchholz to this species, see Note on 

 Buchholz, 1874. He gives some account of Tritwpis heUeri. Boeck, and observes that,
