468 ]Mi-. A. O. Walker on tlie Amphipoda 



Iphimedia ehlance (Bate). Not in the collection. 

 Pereionotus testudo (Mont.). Not in the collection. 

 Acanfhonotus Owem'i (Bate). Six specimens. 

 Now Epimeria cormgera (Fabricius). 



Dexaviine tenuicornis (Rathke). Not in the collection. 



G. 0. Sars rightly conjectures that the species described 

 by B. & W. under this name is not Amphithoe tenuicornis 

 (Rathke), which he identities with D. spinosa (Mont.), but 

 D. thea (Boeck). 



Dexamine vedloinensis (Bate& Westw.) . Not in the collection. 

 Now Paratylus vedlomensis. 



Atylus gihhosus (Bate). 



Now TritcBta gibbosa. T. dolicJionyx (Nebeski) is the 

 adult male of this species. 



Atylus hispinosus (Bate). 

 Now Apherusa bispinosa. 



PJierusa bicuspis (Kroyer). Four or tive specimens. 



This, as I have shown elsewhere, is not Amphithoe bicuspis 

 (Kroyer). It is probably Apherusa {IJalirages) borealis 

 (Boeck). 



Pherusa facicola (Leach). Not in the collection. 



This, as shown in Ann. & Mag. Nat. Hist. ser. 6, vol. vii. 

 p. 418, is Gammarella brevicaudata (M.-Edw.), female. 



Calliope Ossiani (Bate) and G. Fingalli (Bate & Westw.). 



Not in the collection. As pointed out by Boeck, these are 

 respectively the young and old forms of Amphithoe (now 

 Parapleustes) latipes (j\I. Sars, 1858). 



Calliope grandoculis (Bate) . One large and two small 

 specimens. 



These appear to be immature specimens of C. leviusculus 

 (Kroyer). 



Eusirus helvetice (Bate) . Not in the collection. 

 According to Boeck this is E. longipes (Boeck, 1860).
