^{page 165 note 2} The fauna of this horizon of the southern border of the Bassin de Dinant has been made known by Béclard (Bull. Soc. belge de Géol., vol. i, 1887, pp. 60–86)Google Scholar and by Maillieux (ibid., vol. xxiv, 1910, Mém., pp. 189–220). I have given a critical list of the species collected in the Bassin de l' Eifel (loc. cit., pp. 85–132). This list has been added to by Maillieux (Bull. Soc. belge de Géol., vol. xxviii, 1914, Proc. verb., pp. 77–9).

^{page 167 note 4} This is not quite true of the western part of the Bassin de l' Eifel, where the formations are much thicker. There exist between the red and green shales of the Gedinnian and the shales and quartzite of the Taunusian, two horizons: one consists of greenish shales (Schistes de St. Hubert) and the other of quartzophyllades and shales (Lower Taunusian). These two horizons disappear towards the east and in the neighbourhood of Laroche, at the southwestern corner of the “Massif de Stavelot”, the red and green shales of the Gedinnian are succeeded immediately by the slates and quartzites of the Taunusian.Google Scholar
