but also in the tarsometatarsus very specialized, having a broader and flatter middle trochlea than in most of the other species of the order. The specially elongated humerus of Sitta and Certhia. combined with the deeply incised middle trochlea of the tarsometa­tarsus may be mentioned here too. All these osteological features speak for a geologi­cally old origin and for a relict nature of these taxonomical units. These short allusions of the mentioned features may perhaps help in the future in the classification of this group of birds, - the largest order within the class. In any ca­se, the descriptions given in this paper call our attention to the fact that we have to analyse the different bones morphologically in the most subtle details and drawing conclu­sions only from a few features (e. g. the double or single pneumatic fossa etc. ) seems to be an oversimplification of the problem.
