124 THE VOYAGE OF H.M.S. CHALLENGEE. 



doubt that the account is based on imperfect specimens of Proto ventricosa, 0. F. M. Lastly, 

 in this section he places CapreJla, Lamck., with the species acutifrons, Latr.; acuminifera, 

 Leach, (more correctly, acanthi/era, Leach) ; linearis, Linn.; " mantis, Latr., Nouv. Diction. 

 d'Hist. nat. Tete alongee, r^tr^cie posterieurement ; pieds de la seconde paire plus courts 

 que ceux de 1' espfece precedente, avec leurs articles inferieurs comprimos et anguleux. Des 

 cotes de la France baignees par I'Oc^an" ; a species which Mayca- considers quite indefinite ; 

 phasma, Lamck., with Cancer phasma, Montagu, for a synonym, this being Protella phasma. 

 He concludes by remarking that, " M. Latreille regarde encore comme appartenant k ce genre 

 le Cawer filiformis d& Linnaeus, et le crustac^ d&rit par Forskal, Faun. Arab., pag. 87, 

 comme une larve d'insecte d'un genre incertain." 



" 11" Section. Coips large, deprime ; des yeux composes, et en outre deux tres-petits yeux lisses 

 disposes transversalement sur le vertex ; antennes trh-rapprochees a lew base ; pieds au nombre 

 de quatorze, dont dix parfaits, et quatre (places soiis le second et le troisieme segment du 

 corps), en forme d'apijiendiees greles, articules, ou de fausses pattes ; anus avancA et pourvu de 

 tubereules pen saillans." This section has the one genus Cyamus, Latr., with the species 

 ceti. The various synonyms of the genus and species are given, followed by the remark, 

 "de rOcean d'Europe oil il vit sur les baleines, et aussi, selon M. Latreille, sur les scombres 

 ou maquereaux. Ce crustact^ est vulgairement design^ par le nom de pou de baleine." 



In the fifth order, Tsrpoda, Latr., "I" Section. Branchies plac^es sous la queue," etc., he de- 

 fines the first division thus : — 



" I"* Division. Pieds au nombre de dix seulemeut ; corps form^ de trois, cinq ou sept segmens ; 

 abdomen (ou queue) en ayant quatre, cinq ou six, et termini par deux ou quatre lames 

 laterales ; deux ou quatre antennes." In this division he places the genus, now transferred 

 to the Amphipoda, Typhis, Eisso, with the species ovoides, Eisso, remarking as to the defini- 

 tion of the genus that " M. Risso n' annonce comme didactyles que les deux premiers pieds ; 

 MM. Latreille et de Lamarck indiquent les deux suivans comme pr^sentant le meme 

 caracti^re." Under the genus " Jone, Latr.," in the Second Division, Desmarest remarks that 

 Latreille (Encycl. Meth., Expl. des pi.) considers Slabber's Oniscus arenarius suited to form 

 a genus near to lone, but Desmarest himself, though he thinks that Slabber's species has 

 only twelve feet, shows that it is at any rate quite remote from lone. 



Pages 396-420 are occupied with a valuable Bibliographie carcinologique. Pages 421-427 con- 

 tain a supplementary account of various species described by Risso, but not easily to be 

 identified or classified. Among these are his Talifnis rubropunctatus, which Desmarest 

 thinks may be an Orchestia, and his CaprelJa imnctata, which Mayer agrees ^^^th Desmarest 

 in thinking quite indefinite. 



Figures of Amphipoda, borrowed from various sources, are given on plates 45 and 46. Fig. 1 

 on plate 45 is described at the foot of the page as "Phronime si'dentaire, gr. nat." Yet it 

 has evidently been copied with some care from PI. 2, fig. 3, of Eisso's Hist. Nat. des Crust, 

 des Environs de Nice, 1816, which represents Eisso's Fhronima custos, a species, it is true, 

 identical witli Phronima sedentaria, but none the less distinguished from it by Desmarest, 

 who remarks upon it, " Pattes natatoires caudales paroissant n' etre qu' au nombre de 

 quatre," a mark of distinction which beyond doubt belongs to the figure only, and not to 

 the species. Desmarest's fig. 8, on pi. 45, of " Crevette des ruisseaux, gross.," is no longer 

 that of Rosel's species, but no doubt taken from an actual Ghmvianw pulex.

This work is included in Boeck's list, but I can find nothing in it relating to the Amphipoda.
