478 Rev. Canon Norman — A Month on 



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 

 * "NVillcm Barents' Expedition, 1878-84, were 73 t; those of 

 the ' Dijmphna ' Expedition 41 |. ]\Ioreover, the total known 

 Ampliipods 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.

Rodberg, 3-5 fathoms. 



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

 in ' Beitrag zur Fauna der Krym ' closely agrees with 

 H. missoni of the same author's ' Beitriige zur Fauna Nor- 

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

 H. pontica 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 pyriforra hand, with very 

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

 as figured by Eathke, which is indistinguishable from the 

 same organ in H. Nilssoni, Rathke. Heller** gave ten Adriatic 

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

 under IJ. Prevostii^ M. -Edwards (nee Eathke).
