OMEARA, ARCTIC DIATOMS. 531 



British species of Diatoms should have been found in these scanty 

 gatherings from the Arctic regions, their generic and specific 

 characters having been in no perceptible degree affected by con- 

 ditions so different as exist between the climate of the Arctic Ocean 

 and that of our own waters."
