During the publication of this fine work M. de Haan was stricken down with a grievous illness 

 which confined him to his bed for years, but did not prevent his courageously completing 

 the publication (Herklotz). 



The only Amphipod dealt with is " Caprella Kivyeri," of which the author only had a dried 

 specimen to describe, hence, Mayer says, in spite of the good figui'e, it cannot be determined 

 with certainty, though he believes it to be synonymous with Cajrrella mquilihra, Say.

Ueber die Gammarus-Arten der Gegend von Bonn. Von Dr. A Hosius.

 Erster Band. Berlin, 1850. pp. 233-248. 



He complains that Gervais and Milne-Edwards, in attempting to distinguish Gammarus fluviatilis 

 vel ruselii from Gammarus index, disagree with one another, though both dealing with 

 specimens from the neighbourhood of Paris. He assigns Gammarus pulex to Degeer and 

 Gammarus fluviatilis to Rbsel, but as he has never met with this latter species in rivers, he 

 thinks that the name Gammarus ruselii given it by Gervais ought to stand. He enters into 

 a detailed comparison between these two species and the blind Gammarus imteanus of Koch. 

 In regard to habitat, Hosius says that Gammarus puteanus is confined to wells, that he has 

 only found Gammarus ruselii in still or weakly flowing deep waters, but Gammarus pulex in 

 strongly flowing, shallow, brooks, often only an inch deep. In Milue-Edwards' Manual, he 

 says, we must cross out Gammarus pulex, put Gammarus pulex, Degeer, in place of 

 Gatnmarus fluriafilis, and lastly insert Gammarus rdselii, Gervais (or Gammarus fluviatilis, 

 Rosel), and Gammarus puteanus, Koch.
