ADDITIONAL DESCRIPTIONS. 



Having completed my descriptions of the different 

 species of Falconine and Strigine Birds that have been 

 met with in Great Britain, in so far as I have been 

 able to fill np the various compartments of the plan 

 which I had in commencing sketched for my guidance, 

 it now becomes necessary for me to revise the whole, 

 correct the errors which I have committed, and add the 

 observations which I have made since the different ar- 

 ticles were printed. So many fresh specimens and bo- 

 dies have of late been obtained by me, that I am en- 

 abled to add very considerably to the information con- 

 tained in the preceding pages ; and as the tide is still 

 rapidly flowing, I trust I shall ere long be qualified to 

 present to the public several anatomical essays, refer- 

 ring to the birds which form the subject of this volume. 

 In the mean time, I here subjoin such particulars as I 

 judge suited to the present occasion.
