. From the above, list of the contents of the stomachs, it would seem 

 as if Arvicola was almost their only food. But it is but fair to state 

 that i have seen this owl chase sea ducks, especially Histrionicus hi- 

 strioniciis, out at the reef, very much in the same manner as does the 

 falcon. On January 7, 1883, I found on the beach the remains of a 

 ffarelda hyemalis, eaten by a snowy owl. The footprints in the snow 

 were very recognizable from the impression of the feathers of the toes 

 and by the direction of the inner toe at a right angle with the other 

 ones. It may be that even the snowy owl sometimes gets tired of too 

 uniform a diet. * 



The Russian name by which the snowy owl is known by the natives 

 on the islands is " Sitsch,''^ which, according to Pallas, in Russia is 

 applied to Nyctala tengmalmi.
