REPORT ON THE AMPHIPODA. 205 



second gnathopods are not simple, but subchelate, as Rathke's figure represents them. This 

 is only a question of terminology, as may be seen from Rathke's specific description, " An 

 dem zweiten Beinpaare {K) kommen nur Andeutungen von Hiinden vor, indem das letzle 

 Glied derselben kaum etwas breiter, als das vorletzte, iibrigens aber ziemlich lang, tafelartig 

 diinne und mit seinem hinteren nnteren Winkel so hervorspringend ist, dass es hier einen 

 platten, breitcn und abgerundeten Fortsatz bildet, der ungefahr halb so lang erscheint, als die 

 dicht vor ihm eingelenkte Klaue." The type species, to which this description applies, is 

 named Iphimedia ohesa (Tab. III. Fig. 1.). Kr0yer afterwards described th? same species 

 as Microcheles annaia, and Dana, altering the definition, included in the genus species 

 which have nothing to do with it. 

 Podocerus capillatus, n. sp. (Tah. IV. Fig. 8) is said by Ratlike to come near Podocerus varieijatus. 

 Leach, but to he adequately distinguished from it. In this view Bate and Westwood agree 

 with him. Bruzelius named it Jassa capillata. Boeck considers it the same as Podocerus 

 rariegatus, wliich was the type of Leach's genus Podocprus, but he rejects Leach's genus JaK.-<a 

 as synonymous with his Podocerus. Jassa of BruzeUus he alters into Janassa, because after 

 Leach's time Jassa was used for a fish. He then enters Podocerus capillatus, Rathke, as a 

 synonym of Janassa variegata. Leach. But surely, when a genus is retained, the type 

 species must continue to belong to it, and if Janassa variecjata really differs generically 

 from the other species of Podocerus, Janassa must be called Podocerus, and the other species 

 by some other name. The muddle that will ensue may best be avoided by re-uniting Janassa 

 to Podocerus, from which it is separated only by fine-drawn distinctions. Podocerus cal- 

 caratus, n. sp. (Tab. IV. Fig. 94) Boeck unites to Podocerus fahrdus, Montagu. The Caprella 

 phasma, Lamarck, Caprella acuminifera. Leach ? and Caprella scolojKndroides, Lam. 

 (C linearis, Latr.) all belong to Caprella linearis. Leptomera p)edata. Lam. (Proton 

 pedatum, Desmar.) corresponds to Proto ventricosa, O. F. M.

The only Amphipods noticed are Orrliestia hottx, Milne-Edwards, Gammarus pulex, Fabr., 

 Cyamus erraticus, Eoussel de Vauzeme, and Cyamus ovalis of the same author. Liitken 

 notices that the identification by Kraus of Cyamus erraticus ■^iih. Cyamus ceti, Desmarest, 

 is erroneous.
