Biologisch Jaarboek (Dodonaea)
The name of this Belgian journal name was correctly cited, but this journal has volume numbers (serial run was 1.1934 - 67.1999 (2000)). For most articles the journal volume number was given.
But I did not see the volume number in the article cited for De Koning 1947, at some 20 occasions in List A. This volume number should be added.
