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



Leach; Talitrus, Latr.; Atylus, Leach; Gammarus, Latr. ; Melita, Leach; Mxra, Leach; 

 Ampithoe, Leach; Phsrusa, Leach; Dexaminf,, Leach; Leucothoe, Leach; Cerapus, Say; 

 Podoceiiis, Leach ; Jassa, Leach ; Corophium, Latr. ; Pterygocera, Latr. ; Apseudes, Leach, 

 (Eu]pliem% 'Rasso); Typhis, 'Risao ; Anceus, Risso, (Ghiathia, 'Leach) ; Pi-aniza, Lea,ch. These 

 form the third order. The fourth order, Lsemodipoda, ^pl. 63, includes under " De Cyanie 

 {Cyamus, Latr.)," Lepiiomera, Latr. {Proto, Leach) ; Naupredia, Latr. ; Caprella, Lamck. ; 

 and for " des cyames proprement dits," Cyamus, Latr., {Laru7ida, Leach). 



The only part of this work which is of any independent value as regards the Amphipoda is the 

 group of fine plates. 



As to '' Dcoetylocera Nicsensis, Edw.," pi. 58, fig. 2, the editor says, " Cette espece ne me paralt 

 pas differer de celle d&ignee par M. Risso sous le nom de Phrosina semilunata, et cites par 

 M. LatreUle comme type de son genre Dactylocere ; cependant elle ne presents pas Iss 

 caract<^res assign^s par nntre auteur h, ce meme geurs." 



On " Jone thoracicus, Latr.," pl. 59, fig. 1, he says, " il suffit de comparsr ces figures d'une 

 part avec cellss des Talitres et des autres Amphipodes proprement dites, et de I'autre jsart 

 avec cellss des Cymotho^s, etc. (PI. 65), pour se convaincre que co n'est pas ici la place 

 naturslle du genre Jons ; dans la classification adoptee dans mon Histoire Naturelle des 

 Crustacfe, ces parasytes sont ranges dans une division particulifers de I'ordre des Isopodes a 

 la suite des Cymothoadiens." 



Bate and Westwood, i. p. 19. n., consider that ths representation of Talitrus saltator, Edw., 

 pl. 59, fig. 2.a., has in reality been taken from Talitrus Beaucoudraii, Edw. 



The mandible of Orchestia Uttorea, pl. 59, fig. 2.d., seems to show a rudiment of a palp, but 

 unjointed. 



" Orchestia Quorjiana," Edw., pl. 59, fig. 4, is clearly depicted. 



" Gammarus Dugesii," Edw., pL 60, fig. 3, has the remark, " Cette espfecs off're un exempls de la 

 forme dss mains ds la deusi^me paire, qui est caract^ristique du genre Melita de Leach. 

 Genre qui ne parait pas devoir etre adopts." It is in fact a synonym of Melita palmata, 

 Montagu, the type-species of Leach's genus. 



" Pl. 60. Fig. 4. Gammarus brevicaudatus, Edw. Individu male. Ici la main de la deuxieme paire 

 offre les particularites de forme propres au genre Mxra de Leach. " Fig. 4. a. Patte de la 

 seconds paire chez la femelle, conform^o de la meme manifere que chez les Crevettes 

 ordinaires." These are the two sexes of Gammarella brevicaudata. On fig. 5. Melita 

 palmata. Leach, he says, " Ce genre, comme nous venous de le dire, ne paralt pas etre 

 admissible." Fig. 6. " Amphithoe Marionis," Edw., is identified by Spence Bate with 

 Dexamine spiinosa, Montagu. 



Pl. 61. fig. 4, " Podocenis variegatus, Leach," " d'aprfes I'individu decrit par Leacli et conserve,^ 

 dans le Mus(5um Britannique," has the last peraeon-segmeut and the first of the plson 

 dorsally producsd backwards in a vsry marked tooth-like process. 



Pl. 62 bis, is devoted to Typhis ovoides, Eisso, and Typhis Jerus, Edw.; pl. 63 to Caprella 

 linearis, Leptomera ventricosa, and to Cyamus ovalis, Roussel de Vauzfeme. 



1841. Delle Chiaje. 



Descrizione e notomia degli animali invertebrati della Sicilia citeriore. Napoli, 

 1841. 5 vols, folio. 



Bats and "VVsstwood, ii. p. 27, rsfsr to plate xxiii. of this work as containing a figurs of 

 Doliolum papillosmn, Delle Chiaje, with Phronima sedentaria inside it. Claus, 1862, 

 makes a similar reference. Bate and Westwood, loc. cit., also refer to Otto, " Nova Acta," 

 xi. p. 313, and Otto is referred to by Claus likewise.
