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



apijendage. Masillipedes with a squamiform process on the basos only. Gnathopoda 

 subchelate ; second pair the larger ; coxaj of anterior pair well-developed. Fourth pair of 

 00X38 wide, excavated behind to receive the anterior part of the fifth pair. Posterior 

 pleopoda biramous. Telson squaniifonn." Neohule was subsequently transferred by 

 Mr. Haswell to the Orchestidse, and perhaps is synonymous with Hyale, Eathke. 



In the subfamily Lysianassides, the genus Ghjcera is defined as follows : — " Superior antennas 

 slender, rather long, provided with an appendage. Mandibles with a palp, the incisive 

 edge not toothed ; no accessory plate ; anterior margin with a prominent tubercle. 

 Maxillipedes with large squamiform processes on the basal joints. Four anterior pairs of 

 cosfB deeper than their respective segments, the fourth pair slightly produced inferiorly and 

 posteriori}'. Gnathopoda filiform, slender ; anterior pair smaller than the posterior, 

 imperfectly subcbelate ; posterior pair subchelate. Posterior pleopoda biramous ; the rami 

 broad-lanceolate. Telson double." The name Ghjcera, being preoccupied, was sub- 

 sequently changed to Gli/cerina. 



In the famUy Corophiidse, subfamily Podocerides, the genus Xenucheira is thus defined : — " Body 

 slender. Coxse small. Superior antennae very long, longer than the inferior pair, with a 

 secondary appendage. ]\Iandibles with an appendage. P)0th pairs of gnathopoda non- 

 subchelate, armed with very long hairs ; carpus of posterior pair broad, plate-like, applied 

 to the anterior (dorsal) border of the meros. Posterior pleopoda biramous. Telson 

 simple." 



The genus Haplochcira is thus defined: — "Body not much compressed laterally. Upper and 

 lower antennaj subequal ; superior pair without an appendage ; inferior subpediform. Both 

 pairs of gnathopoda simple, fringed with long hair. Posterior pleopoda biramous, with 

 unequal rami Telson single ? " 



1880. Haswell, William A. 



On some additional new genera and species of Ampliipodous Ci'ustaceans. 

 From the Proceedings of the Linnean Society of New South Wales. Vol. IV. 

 pp. 319-350. Pis. XVIII.-XXIV. 1880. 



The new species described, and in almost all cases figured, are, Allwchestes niger (not figured) ; 

 Gyp'oidia ornata; Cijxwoidia lineata, not improbably female or young form of Cyp'oidia 

 oniata ; Lysianassa australiensis, to be placed with Lysianassa nitens, Haswell, as at most 

 a variety ; " Moniagua Miersii;" Mmitagua longicornis (in which, as in the preceding 

 species, the mandibles not being described, the genus remains doubtful between Stenothoe 

 and 3Iefopa) ; CEdicenis latrans ; CEdicerus arenicola, perhaps, according to Haswell, 

 identical with CEdicerus fossor, Stimpson ; Urothoe pinguis ; Jphimedia ? amhujua ; Atylus 

 inonondoides ; Atylus lijjpus ; Leucofhoe norse-hoUandix ; Harmonia crassipes; Eiisirus 

 [really Liljehorgia] duhuis; Mo'rcc [Paramenia Chilton] dentifera; Mwra hamigera; 

 Mcera viridis; Ma'ra apjrroximans, probably to be imited with Mo;ra [Paransenial'] 

 dmiifera; Megamxra szihcarinafa ; Megaman-a suensis ; "■ Megamara Boeckii;" Wyoillea 

 Jongimanus ; Ampldthoe quadrimayms ; Podocerus australis ; " Microdeuferopus Mortoni;" 

 Microdeuterop>us tenuipes (this being in Chilton's opinion the female, and the preceding 

 species the male, of Aora ///j)/fa, Kr0yer) ; Microdeideropus chelifer; "Coloniastix Brazieri;" 

 Ci/iiophium dentaturn (in 1886 re-named Dexiocerella deiitaia) ; Cyrtophium minufum ; 

 Icilius pninciatus, afterwards identified with Icilius australis; Pohjchei'ia [properly Tritecta] 

 tenuipes ; PoJycheria [Trifa;ta] hrevicornis, unfigured and probably a form of the preceding 

 species ; Caprella echinata, since transferred to Protella ; Caprella corniyera, referred later
