REPORT ON THE AMPHIPODA.

To his new species, Caprella grandimana, Mayer assigns the earlier " Caprolla Dohrnii," Hallcr, 

 as a synonym, apparently rejecting Haller's name on the ground of some uncertainty 

 connected with his species, and what seems to be an error in the description. It must be 

 observed also that the name CtqireUa inermis, Haswell, requires to be changed, having been 

 already used by Qrube for a different species. As it appears to be undistinguishable 

 " from Caprella DimUevsMi," Czcrniavski, it may as well be known by that name. With 

 Caprella tuherculata, Bate and Westwood, Mayer suggests the possible identification of de 

 Queronic's Puce de Mer arpenteuse. Fig. A., B. (1780), which in my opinion is quite out of 

 the question. 



The genus Podalirius, Kroyer, receives three species, distinguished in the following table : — 



" Palmarrand der Grossen Greifhand beim Mannchen mit einem 

 kleineren proximalen und einem grosseren medialen Fortsatz, . 

 " Palmarrand der Grossen Greifhand ohne den medialen Fortsatz : 



Hinterbeine enorm verliiugert, Palmarrand ohne Einschlag- 

 haken, ...... 



Hinterbeine kurz, Palmarrand mit Einschlaghaken, 



Traces of the first and second peraeopods are stated to be present in " Podalirius Kniyeri 



Podalirius ininuttis is assigned as a synonym Podalirius typictis, Hoek. 

 Under the head of Phylogenie, at page 192, the following hypothetical table of genealogy is 



given : — 



P. typieus, Kroyer. 



P. Kriiyeri, Haller. 

 P. minutus, n. e." 



To 



Podalirius ? 



Cyamiden. 



Caprella.

Procaprellide. 



One hundred and thirty-one works are mentioned in the Literaturliste and Nachtrag, page.<? 



194-201, which, with a few unavoidable exceptions, have been carefully studied and 



are here minutely criticised by Jlayer. 

 Taf. i., a double plate, gives figures, lateral and dorsal, of both sexes of the following species,
