The first representative of this germs is, as far as I know, Hyperia pedestris, described 

 by Guerin-Meneville; he gave a very good drawing of it and a short description, 

 probably in the year 1836 in the work »Icono°:raphie du Regne Animal de G. Cuvier. 

 Crustaces». Paris 1829-1843, p. 22, pi. 25, fig. 6. However, it was not mentioned by 

 H. Milne-Edwards in his classical work »Histoire des Grustaces» of 1840. Spence Bate 

 did not quote it in his Catalogue of the Amphipoda of the British Museum. A. Boeck 2 ) 

 in 1875 overlooked it; Th. Stebbing 3 ) in 1888 cite Hyperia pedestris in his excellent 

 review of the literature concerning the Amphipoda, but without any remarks on its place 

 in the system. I for my part am convinced that it is a true Paraphronima, and I think 

 that only the examination of the drawing will be sufficient to prove its kindred. 



Glaus in 1878 4 ) mentioned, and in 1879 gave the diagnose of the new genus Para- 

 phronima, at the same time he mentioned, rather than described, two species: Paraphro- 

 nima gracilis and P. crassipes. In 1885 (see above) the author of this treatise proposed 

 three new specific names: Paraphronima californica, P. Edwardsii and P. clypeata. 

 The first of them was later (1887), when 1 had the opportunity of examining a male 

 specimen, made the type of a new genus Dairella. The second turned out to be only a more 

 developed form of Paraphronima gracilis, Glaus, the error owing to the very incomplete 

 original description of the latter species. In 1887 (see abowe) I proposed the new specific 

 name Paraphronima pectinata for a Paraphronima distinguished by the strongly 

 pectinate armature of the inner ramus of the last pair of uropoda, but the subsequent 

 examination of new and fresh material, kindly entrusted to me by Professor T. Tullberg 

 of Upsala, proved that this pectination is only a sexual caracteristic, and that Para- 

 phronima pectinata was the male of P. clypeata. At the same time I found the male 

 of P. gracilis, which was not known by Claus. Just as this sheet was to be printed 



! ) Already in 1878 Clans mentions the new generic name Paraphronima in »Ueber Herz und Gefiiss- 

 systera der Hyperiden»; Zoologischer Anzeiger, I, p. 270, but without the slightest diagnose, therefor I must cite 

 »1879» as the right year for the date of the generic description.
