one annual volume, and contains a good deal of interesting 
matter. The editor, Baron Snouckaert van Schauburg,

Sumatra by Heer van Heijst, which contain several birds 
new to this island, viz.:— Falco peregrinus ernesti , Monticola 
solitarius pandoo , Criniger finschi, and Kenopia striata. 
He also has his annual report on the occurrence of rare 
birds in Holland from October 1919 to September 1920. 
Heer H. C. Siebers discusses the status and relations of 
Corvus cornix and C. corone , and whether they should be 
considered as distinct species or only subspecies, and Heer 
A. Hiverson continues his essay on the birds of the Javanese 
rice-fields ; Heer C. G. B. ten Kate has a note on an old 
work on whaling and the natural history of the Arctic 
regions by C. G. Zorgdragers, published in 1728, and 
endeavours to identify the birds mentioned therein. Finally, 
the third part is occupied by a paper by Dr. E. Stresemann 
in German on the origin of the fauna of the Alps and other 
mountain ranges of central Europe.
