oï the newborn Wryneck was further developed at hatching stage. The striataj 

 -egions at this stage are distinguishable. The wulst , however, is not yet 

 iifferentiated. The lumen of the ventricle is smaller than in Dendrocopos. 



Dennler (1919) believed that the forebrain structure of the Wryneck indicated 

 :hat this bird must be separated systematically from the Woodpeckers. According 

 :o my results, Wrynecks and Woodpeckers belong to the same braintype.
