the geographical range and diversity of plumage of each species. 

 Beside the specimens obtained by the donors themselves during 

 their travels in Central America, or by collectors who worked for 

 them, it contains a very complete series of South- American Birds. 

 As the arrangements for depositing this collection in the British 

 Museum were not completed before a large portion of the volume 

 had been printed, a considerable number of the specimens had to be 

 enumerated at the end of the work, among the "Addenda." 



Of the other donors who have contributed to the series described 

 in this volume, I have to mention the U.S. National Museum, Capt. 

 Stackhouse Pinwill, Col. Swinhoe, Capt. Bingham, W. Davison, Esq., 

 Dr. Jentink, Hr. R. Collett, Edward Newton, Esq., C.M.G., Dr. 

 Taczanowski, and Prof. Giglioli.
