REPORT ON THE AMPHIPODA. 583 



mandible has no palp. The genus CalUmerus, Stabbing, is a synonym of Amphilochuii, Sp. 

 Bate. CaUio2)e, Leach, being preoccupied, must yield to Calliopius, Lilljeborg. Of the 

 genera Madeaijia and Pnlijeheria, Haswell, named as genera related to Issea, M.-Edw., the 

 former is a synonym of Wyvillea (see Notes on Haswell, 1880), the latter is synonymous 

 with Tritseta, Eoeck. Ceradocus, Costa, in which the third uropods have both rami 

 elongate, is here given as a synonym of Melita, Loach, although in regard to the third 

 uropods of that genus it is rightly said, " ihre lunenlamelle stark verktirzt." Goylana, 

 Wrzesn., is made a synonym of Gammarus, without notice of the curious coalescence 

 of segments which distinguishes the former genus from the latter. Amathia, Eathke, 

 being preoccupied, must give place to Amatldlla, Sp. Bate, and not vice versa.

In an " aperQU de la faune actuelle de I'estuaire," the Crustacea are said to number about sixty- 

 five species, and " parmi les plus interessantes " are included six species of Amphipoda, none 

 of them new. Two other species are named in the following observation, " deux espfeces 

 tr^s affines, les Gamnmrns locusta, L. et Gamvi. pulex, L. = Oamm. fluviatilis, H. Milne- 

 Edwards, sont trfes aboudantes dans la Seine et a son embouchure. La premiere de ces 

 deux espfeces, le Gammarus locusta, se tient constamment dans I'eau salee, tandis que le 

 Gammarus pulex, tres difficile a distLnguer du precedent, vit a la fois, d'apres mes 

 observations, dans les eaux salves, saumatres et douces."

This is practically the same paper as that already noticed in the Note on Koehler, 1885, p. 566. 

 For " Erysthrmus edriophtalmus Sp. B.," " Erysfhceus eryfhropldliahmis Sp. B." is here 

 read, so that Eurystheus erythropldhalmus is clearly intended. Some other obvious 

 corrections of nomenclature are requisite in the lists given.

 which the following were conspicuous for the very large number of specimens met with ; —
