In addition to my first paper on this subject on page 55 of the present volume, I give here an enumeration of recoveries of birds, marked on account of the Leyden Museum in 1911 as well as in 1912. The number of the birds marked in 1912 is considerably surpassing that of them marked in 1911. I cannot give now the exact number of marked birds nor a complete list of the species, as many of our cooperators did not yet sent to me the filled-in schedules.
