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



zung des Kopfes mit den folgendeu Segmenten, und ware es auoli nur das vordetste des 

 Bruststiickes, der sogennauten Prothorax, zur Eegel geworden." He divides the Crustacea 

 into seven orders, the Amphipoda standing sixth, between the Isopoda and Decapoda. At 

 page 89 he defines the Amphipoda ( Flohkrebse), as " Getrennt-schechtiiche Krebsthiere mit 

 cntwickeltem Bruststiicke, von den Seiten her zusammengedriicktem Leibe, und kiemenlosen 

 Postabdominal-Gliedmassen." The ilhistrations are taken from " Arapiiithoe Jurinii" 

 M.-Edw.; Gammarus iieglecius, IaH].; Gammarus locusta, Montagu; Caprella linearis, h.; 

 and Fhrom'ma sedentaria, Forsk. Fig. 10-14, " Gammarus iiegleetus, Lillj. Partie eines 

 sehi' vergrosserten Embryos," exhibits the heart with six " seitliche Spaltijffnungen." Of 

 the eyes it is said, " Die zusammengesetzten, sitzenden Augen werden von der zu einer Horn- 

 haut umgewandelten, ganz glatten, niemals facettirten Kbrperdecke iiberzogen."

" Caprella nova-zealandix, sp. nov.," is described. It is said to approach " C. geometrica, Say, 

 from which it differs, however, in the form of the spine on the cephalon, in the length 

 of the antennae, and in the articulation and arming of the second pair of gnathopoda." 

 Mayer considers that this, together with Caprella caudata, G. M. Thomson, is probably a 

 local variety of Caprella sequilibra, Say. A second species is described as " Caprella lohata, 

 Gudrin." 



In Notes on Some Neio Zealand Crustaceans, [Read, hefore the Wellington Philosophical Society, 

 Ufh January, 1879]. Trans. N. Z. Inst. Vol. xi. pp. 401-402, Mr. Kirk mentions the 

 capture of Podoccrus cylindricus, Say, and Pleusfes panoplus, Kroyer, at Worser Bay. He 

 says, " these are both Arctic species, and their occurrence on our coast is somewhat remark- 

 able." It has since been suggested that the Pleustes is a variety.

On the antennse of the Amphipoda, Leydig distinguishes : — 



1 Gewohnliche Borsten. These ordinary bristles, for most of their length dark-rimmed, 

 but with bluntish ends of finer, clearer structure, and often a fine hair given off some way 

 short of the termination, are found on other parts of the body as well as the antennae. 



2. Fiederborsten. These plumose bristles, spoken of by Humbert as " capsules sensitives," may, 

 Leydig says, be sensitive, but they are not capsules, they are modified pores (Hautcaniile). 

 For the explanation of the like in other Crustacea and in insects, he refers to his own 

 work Ueber Geruchs- und Gehororgane der Krebse und Insecten., Archiv f. Anat. u. 

 Physiol., 1860. Between this and the preceding class he places a sort of Halbfiederborsteu, 

 such as are found on the rim of the head and the back of Gammarus puteanus. 



3 Cylinder oder Keulen. In these cylinders or clubs, the end swelling into a sort of knob
