REPOET ON THE AMPHIPODA. 403 



on the cliaracters of the families and subfamilies, which Eoeck describes at great length. 

 Occasionally there are discrepancies between the one set of characters and the other, wliich 

 is excusable in so comprehensive a work. For instance, the character of P/afi/cyamus does 

 not suit the words " segniento trunci Imo cum capite coalito " included in the definition of 

 the family Caprellidee. Several of the subfamilies have been by some accident wrongly 

 numbered in the original.

Mr. Brady says, " The higher orders of Crustacea are almost always represented in salt-marsh 

 pools by Careinus mxnas, Palannon varians, Crangon vulgaris, Mysis vulgaris, Gammarus 

 locusta, Gorophium longicorne, and Spheeroma rugkauda; in Hylton Dene I met also 

 with Orchestia Uttarea, and at Seatou Sluice with Oniscics asellus." In the " debateable 

 ground" between fresh and brackish water at Hylton Dene he found Coropliium longicorne 

 along with Palsumon varians and Mysis vulgaris,

"He regards the dorsal spine as a very essential character of Zoea, and thinks that the dorsal 

 accumulations of cells in the embryos of some Isopods and Amphipods, the so-called 

 micropyle-apparatus in the Amphipods, the dorsal sucker of the larvae of Limnadia and the 

 Cladocera, the frontal fixing apparatus of Caligus and Ghdlimus, and the peduncle of the 

 Cirripeds are to be regarded as transformations of the dorsal sjsine of Zoea" (Dr. von 

 ^lartens in Zoological Kecord for 1870).

Praemissus catalogus Crustaceorum amphipodum, inventorum in mari albo et in

In all, fifty-two species are named in this catalogue, but, as usual in such lists, some deduction 

 must be made from the total, on the score of synonyms entered as separate species. 

 Notice is given, without any description, oi Montagua variegata, n. sp., " Lysianassa Goesi," 

 n. sp., " Ampelisca Koreiii," n. sp., " Oediceros Brandtii," n. sp., Uruios, n. gen., Uruios 

 viridis, n. .sp., with the remarks " similis Gammaro longicaudas Brandt (mari Ochotico). 

 Hab. mari glaciali ad litus murmanicum (ad insulas Gavrilienses)," and " Duliclda 

 Malmgreni," n. sp. 



It is not easy to see what object is served by publishing names of undescribed species and 

 genera, which neither convey any information of importance, nor can reasonably establish 

 any claim to priority of discovery.
