') Baron R. SNOUCKAERT VAN SCHAUBURG, LL.D.,was so kind as to inform me that the investi- 

 gation instituted by him in consequence of the separation made by Hartert of the English 

 Song-Thrush-form under the name of clarkei, which only became known after the publication of 

 the former's „Avifauna Neerlandica", had shown that this form is also breeding in this country, 

 so that in the said ..Avifauna" (p. 44): ,,106. Turdus musicus musicus L." should be struck out 

 and replaced by: 



106. Turdus philomelos clarkei Hart. Breeding. 



106a. Turdus philomelos philomelos Brehm. Migrating.
