The above summary includes all the species and sub- 

 species of Birds of Prey — i. e., all known and accepted as such 

 on the best obtainable evidence up to November 1st, 1894. 

 At least one specimen of every species given in the preceding 

 lists as forming part of the collection at Norwich will be 

 found stuffed and on view at the Castle Museum. This is 

 more than can be said for our great National Museum at 

 Kensington, where it is only possible for a selection to be 

 exhibited.
