families Tanaidae, Munnidae, and Munnopsidaj are largely 

 represented in Norway ; the first of these has been little 

 studied in our own seas, wliile the two latter families are 

 lovers of a soft muddy bottom and, for the most part, of a 

 considerable depth of water, conditions rarely met with on or 

 off our coasts ; but there can be no doubt that our fauna 

 will hereafter be enriclied by many additions in these three 

 interesting groups. 



The Norwegian seas are very rich in Amphipoda, and here 

 again many groups are more largely represented than in 

 British seas on account of the greater depth of water and 

 the nature of the bottom of the fiords ; but there can be 

 no question that the much larger number of Amphipods 

 known in Norway as compared with the British fauna 

 is due in no small degree to the fact that the Norwegian 

 Amphipoda have been more thoroughly studied than the 

 British. The following is a comparative statement of the 

 number of Amphipoda at present known in Norway, 

 Denmark, Britain, and the Mediterranean ; the species of 

 Norway are from Sars and Boeck, those of Denmark are 

 taken from Meinert's works, those of Britain are from ray 

 own computation (including some unrecorded species), those 

 of the Mediterranean are on the authority of Glaus, Delia 

 Valle, and Mayer.

When we pass to the consideration of the Entoinostraca, 

 we find that these, with the exception of one group, have 

 been more studied and are better known in the British fauna 

 and in that of the Mediterranean than in Scandinavia. With 

 respect to Copepoda of the latter country the only papers 

 Ave have are those of Boeck, published many years ago. 

 The Ostracoda of the Norwegian seas have, however, been 

 worked at both by Professor G. 0. Sars and myself. One 

 hundred and eighteen species of marine Ostracoda are now 

 known from that coast "^ and one hundred and forty-six from 

 our own f.
