than 93 are oceanic species of the tribe Hyperidea ; that the 

 total number procured by the ' Voringen ' Expedition during 

 three summers' work was 149 * ; that the Amphipods of the 

 ' Willem Barents ' Expedition, 1878-84, were 73 t ; those of 

 the ' Dijmphna ' Expedition 41 J. Moreover, the total known 

 Amphipods of Greenland are 151 § ; of Denmark 122 || ; of 

 the British Isles about 236 ; of the Mediterranean 143^. 



Sars's admirable and complete work proves how extremely 

 rich the Norwegian seas are in Amphipoda ; and the fact that 

 I only found one undescribed species testifies to the thorough- 

 ness of his examination of the fauna.

Surely this is H. pontica of Rathke. That author's figure 

 in ' Beitrag zur Fauna der Krym ' closely agrees with 

 H. Nilssoni of the same author's ' Beitrage zur Fauna Nor- 

 wegens,' with one important exception. The last uropods of 

 H. fontica are figured and described as two-branched ; but 

 there would seem to have been some mistake here, since no 

 allied form has such uropods. Delia Valle unites the two 

 species ; but then his figure (pi. xvi. fig. 5) of the second 

 gnathopod of male, which gives a pyriform hand, with very 

 oblique palm, does not agree with that organ in H. pontica 

 as figured by Rathke, which is indistinguishable from the 

 same organ in //. Nihsont, Rathke. Heller** gave ten Adriatic 

 species of this genus, the whole of which Delia Valle includes 

 under H. Prevostu, M. -Edwards (nee Rathke).
