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



Talitee. Talitrus.'LatT.," contains two species, " 1. T. Gammarelle. T. Gammarellus, 

 Latr.," which is Orchestia gammarellus, PalL, and " 2. T. Tachet£ de rouge. N. T. 

 ruhwpundatus. N. T. Chelts inmimis; pecUhus secundo parilongissimisaincc ovatis, acutis. 

 Cette nouvelle espice a le corps comprim6, d'un jaune clair, transparent ; compose de dix 

 segmens tachetes de rouge. Sa tete est presque triangulaire, ses yeux sont r^niformes, 

 reticules ; ses antennes sup^rieures presque aiissi longues que les infc^rieures, avec les deux 

 premiers articles tres-gros et fort longs. Lo premier de ces infurieures est court et renfl^. 

 La premiere paire de pattes est grele, courte ; la seconds est longue avec leur dernier 

 article ovale, tachetd de rouge et termine par un crochet. La femelle porte des oeufs 

 blanchalres, en avril. Dimens. long. 0,015. larg. 0,004. Sojour : dans le golfe de Nice." 

 This species is not included in the general lists either of INIilne-Edwards or Spence Bate, 

 although the latter writer notices Enone punctata, which is evidently the same species, re- 

 named but treated as new, by Kisso in 1826. That it is not a Talitrus may be inferred as 

 well from the description of the antennse as from Risso's preliminary remark, evidently 

 referring to this species, " une des deux espoces que je vais decrire se tient en pleine mer, et 

 sautille toujours a la surface de I'eau pendant les calmes de I'^t^." " G. xxxv. Ceevette. 

 Gammarus. Fabr.," "Espfece. G. Puce, G. Pullex. Fab." " Var. A. On trouve des individus 

 colore d'ua rouge pale au vallon ohscur." Pullex in the errata is corrected to Pulex. 

 After Gammarus follows "B. Queue sans appendices. G. xxxvi. Cheveolle. Gaprella. Latr." 

 " Espfeces. 1. C. LiN^AiRE. Latr. C. Linearis. Latr.," " 2. C. Ponctu^e. N. C. Punctata. 

 N. C. Pedihus anticis hreiiihus ; secund.o tertioque pari longissimis monodacfijUs. N." 

 These two species of Cajrrella are given up by Mayer and V. Carus as incapable of 

 determination." "G. xxxvii. Cyame. Cyamus. Latr." "Espeoe. C. De la Baleine. 

 C. Ceti Latr." Of this Liitken thinks that Eisso's description is original, though possibly 

 he may have described a northern specimen, and taken for granted that the species 

 occurred in the Mediterranean. After the specific description Risso adds, "Les cyames 

 paroissent presenter les memes mceurs et les memes habitudes que les caliges. Ces 

 animaux se fixent indififeremment sur les c^taces ou sur les poissons pour se nourrir h. leurs 

 depens. Les thons qui en sont quelque fois atteints paroissent souifrir beaucoup de ces 

 botes incommodes, et lorsqu'Us en ont im tres-grand nombre, ils sont saisis d'une sorte de 

 fureur qui les porte k sauter tres-souvent bors de I'eau. Dimens, hmg. 0,012. larg. 0,008. 

 Sejour : sur les Baleinoptires et les Scombres."

Boeck says that the anatomy of Cijamus is given, with figures of the male and female, the mouth- 

 organs, and intestines. The mouth-organs are considered to resemble those of Oniscus, but 

 to be simpler in construction. The author was uncertain as to the form of the second 

 maxilla, and could not make out whether the mandibles had a palp or not. The stomach he 

 found to be quite simple, without salivary or biliary duct. To the nerve-cords he attributes 

 seven knots or ganglia ; the heart he describes as an organ broad in front, narrow behind. 

 He also describes the cylindrical branchije. He considers that the genus may stand in the 

 same family with Oniscus, and that it does not belong to Squilla, as de Geer, or to Cancer
