 are to be met with in their neighbourhood. 



The old birds, together with their young, were 

 obtained between Shoreham and Worthing, on the 

 coast of Sussex, in June, 1874.

 in September, 1875.

 and Bass Rock, together with all the islands in the

 of Ross-shire and Sutherland on the west. 



The case is copied from a sketch made on the
