566 THE V^OYAGE OF H.M.S. CHALLENGER. 



this description it seems jsossible that Harmonia may be a synonym of Gruhia, Czerniavski, 

 1868, but for that genus the mouth-organs have not been described. 

 Cyrtaphmm dentatum, Haswell, pi. xvii., figs. S-12, is transferred to a new genus, De.viocerel/a, 

 described as difl'ering from Dana's genus Cyrtoiiliium as defined by Spenoe Bate, by "the 

 superior antennas having a short, multi-articulate flagellum and a well-developed secondary 

 appendage." This is obviously the same as Dana's Plafophium. See Note on Dana, 

 1852. Dexiocerella Ivhata, pi. xviii., figs. 6-8, and Dexiocerella Ixvis, pi. xviii., figs. 10-12, 

 are described and in part figured, as new species belonging to this genus. Cyrtopliium 

 liystrix, Haswell, is transferred to Lxtmatopldhis, Bruzelius, since the superior antennse 

 have no secondary appendage, and the second uropods are wanting. Cijrtopildum minutum, 

 pi. xviii., figs. 1-5 and fig. 9, remains as satisfying the requirements of Spence Bate's 

 definition of CijrtojMum, while Cyrtopliium parastticum, pi. xvii., figs. 1-7, is stated to be 

 a connecting link between the new genus Dexiocerella and the old CyrtopMum, since 

 it " has the flagellum of the lower antennfe well-developed and indistinctly multi-articulate, 

 but has no appendage to the superior antennae. " The genus of Bruzelius is given as 

 Lxmatopihilus, but there cannot be any doubt about the true spelling, as Bruzelius derives 

 it from XoLT/ia and (f>i\o?. Some additional figures and particulars are given for Proto 

 novss-hoUandix, pi. xviii., fig.s. 13-16.

 Extract from the Bulletin de la Societe des Sciences de Nancy. 



Among the 126 species of Crustacea which Dr. Koehler took in the Channel Islands, and 

 principally in Jersey, were several Amphipods, which he enumerates. At Sark he took 

 several specimens of Aora gracilis, which, however, is not, as he supposes it, rare. 



A species of Gammarella, closely allied to Gammarella hrevicaudcda, he projjoses to name 

 GammareUa longicornis, from the length of the antennae, but this is too variable a 

 character to be any criterion of a distinct species, and the specimens, as Dr. Koehler 

 informs me, had accidentally been dried up, before he could submit them to detailed 

 examination. He mentions, among other common Aniphipoda at Jersey, Erystlirmus 

 edriophtalmus, Sp. B., which is in all probability a slip of the pen for Eurystlieus erythroph- 

 thahnus. Thirty-two species of Amphipoda were observed. From Guernsey Dr. Koehler 

 has since sent me a specimen of Atylus vedlomensis, Bate and Westwood.

In the " Biological Observations," the recorder mentions " Several new Gregarinidx found in 

 Poriunus, Carrinus, Pachyijrap)sus, JDromia, Nicoea [ ? Nicea], PJnvnima, and Caprella ; 

 J. Feenzel, Arch. mikr. Anat. xxiv. pp. 545-579, pi. i. figs. 1-69." 



Under "Geographical Distribution," he mentions, from papers which I have not seen, the 

 occurrence in Limfjord, Jutland, of two CapreUidae, on the authority of "J. Collin, 

 Limfjordens marine Fauna, pp. 21 & 22," and in the Baltic of eleven Amphipods, 

 including the fresh-water Gammarus pulex, on the authority of " M. Braun, Arch. Nat. 

 Liv. (2) X. pp. 98-102, 114, & 112."
