Laniidae (Plate V, Fig. 4 and 6) The humerus of the members of this group is rather more inflated (pneumatized) than in other forms of similar morphology. Fossa tricipitalis shallow, longitudinal fold in this field (defined in Bombycilla) indistinct, crista pectoralis relatively long, in margo caudalis proximally a distinct impression, tuberculum ventrale from caudal view relatively short, tendency for Pneumatisation in fossa tricipitalis. I had the possibility to examine the corresponding bones of all the four European species and in my (partly very modest) comparative osteological material these forms differ absolutely in their measurements: length width of diaphysis Lanius excubitor (n=l) 26.4 2.5 Lanius minor (n=8) 24. 6-26.0 2.0-2.4 Lanius collurio (n = 7) 19.6-21.0 1.6-2.0 Lanius senator (n=4) 21.0-22.2 1.8-2.0 Prunellidae (Plate V, Fig. 1 and 7) Members of this family belong to the morphological group characterized by the morphotype in which "fossa tricipitalis and pneumo-anconaea is confluent, not separated", in the taxonomical key No. 8. (5). Some distinctions within this group are given in the description of Motacillidae. Let us give here a characterisation in detail; the whole proximal epiphysis narrower than in other members of this group and hereby the outer margin of crus ventrale fossae more reduced, the angle between the diaphysis and proximal epiphysis (ventrally) composing a wider angle. Fossa tricipitalis shallower (sometimes a tendency to Pneumatisation), proximal part of margo caudalis not forming a distinct fold as in Fringillidae, Motacillidae, Emberizidae, Remizidae or Aegithaliidae. Crista pectoralis relatively short, dorsally not outstreched, distally blunt, distal epiphysis broad, processus supracondyloideus well developed. The two Central European species of the genus are in their measurement absolutely different: length proximal distal width of the width diaphysis Prunella modularis 16. 5 5.0 4.3 1.6 Prunella collaris 22. 5 7.6 6.2 2.1 Sylviidae (Plate I, Fig. 2; Plate VI, Fig. 1-7, 9-12 and 14-16) Warblers in the wider sense belong to the so-called "rather ill-defined families of small insectivorous Passeriformes in the ornithological literature.
