Descriptions of some New Birds in the Museum 

 OF THE Earl of Derby. By Dr. Kaup. 



During my visit to London last year I had the honour to receive 

 an invitation from the Earl of Derby, to visit his collection at Knows- 

 ley Hall, with permission to use the materials I might find there for

 ness of this noble collection. It contains more than 14,000 speci- 

 mens of stuffed birds, besides skins, which are not yet numbered.
