The following communications were received and read : — 



I. Notice of the Birds of Madeira, in a letter 



addressed to the secretary. 



By Edward Vernon Harcourt, Esq. 



Sir, — According to your request, I send you a short account of 

 the birds that breed in Madeira, together with a list of those that 

 visit the island. 



The birds of Madeira are less numerous than might be expected in 

 so genial a climate, and most of them are merely varieties, where they 

 differ from European species.
