from the two islands, except as regards the wings, where the skin and 

 feathers still remain on the skeleton. In the latter the coloration of 

 the whole flipper is about the same as in the last species, but in the 

 skin from Kerguelen the under side has less black, especially at the 

 tip. In the absence of any proof to the contrary, I have assumed 

 that the skeleton is the true ehrysocome. 



The following table gives comparative measurements of our three 

 specimens of JE. chrysolophus and two of E. ehrysocome, one of 

 them (the skin) being var. atrifrons :
