Explains how, owiug to the presence or absence of the glanconitic 

 clay, the underlying Laekenian beds are sometimes fossiliferous and 

 unaltered, and sometimes unfossiliferous and altered by percolation. 

 This is likewise the case with the upper calciferous Bruxellian. The 

 presence of the Chamois sands having been also proved overlying the 

 glauconitio clay, the true age of the unfossiliferous sands (altered by 

 infiltration) is now demonstrated. G. A. L.

 First instalment of a monograph by the author and H. Miller, on 

 the Belgian Pliocene Foraminifera. Describes the Lower Antwerp 

 Bands (formerly called Diestian), giving lists of fossils of the sub- 

 divisions. The movement of the area of deposition towards the N.W. 

 by elevation and depression, and the alteration of the deposits by re- 

 moval of carbonate of lime and oxidation of glauconite, are dwelt on 

 at length, as is the synonymy of the subject. W. H. D.

Concludes, from the fact described as characterizing the horizon met

the overlying Pliocene sands. G. A. L.

Gives a longitudinal section of tlie heights of Neauflcs, Dangu, and 



Vcsly, and a vertical section of the clay-pit in which the Lcjndosfeus 



bed is best seen, and where the junction between the Tertiaries and tho 



Chalk is shown. The dei)osit in question is a true Tertiary bone-bed, 



between tho Lignitic series and the Cuiso sands. G. A. L.
