by others, and by what can be seen in the skins of that bird in the British Museum 
collection. We had no opportunity of obtaining fresh examples of the young of 
Megalestris antarctica, but from all accounts it would appear that the tone of the. 
downy plumage in maccormicki is much more bluish than it is in the nestlings of 
antarctica, and it would be interesting to know whether the feet and legs and bill in 
life show any corresponding divergence from the distinctly blue colour in McCormick’s 
nestlings (see Birds, Plate XIII., Figs. 1 and 2). 
This is a point which can only be settled by reference to fresh specimens, for the 
nestlings of McCormick’s Skua which were brought home by the ‘ Southern Cross’ have 
altered from bluish grey to the brownish tone they now possess, and no doubt the 
skins of nestlings of Megalestris antarctica have altered in a similar manner.

From Mr. Howard Saunders I take the following notes as to the range of Wilson’s 
Storm Petrel :— 
It has been recorded from Louis Philippe Land; from Deception Island in the 
South Shetlands; probably also from South Georgia, under the name Oceanites 
melanogaster, by Steinen; from Gerlache Strait by the ‘ Belgica,’ and from Cape
