Gives a section of clays and sands in a railway-cutting at the former 



place ; the lowest bed belongs to the lower part of the Ostricourt 



sands (U. Landenian). The clay at Dieu-de-Marcq is a lenticular 



mass lying upon sands similar to those of Mons-en-Baroeoul. 5 teeth 



of Otodus are recorded from this hitherto unfossiliferous deposit. G. A. L.

E. Roraer has described this quartzite as considerably older than the 

 Coblentz Grauwacke (L. Devonian), and from the occurrence of Pcn- 

 tamerus rhenani/s has referred it to the Silurian [see Geological Record 

 for 1874, p. 93]. It has been mapped on the Wetzlar sheet of the 

 large map of the Rhine Province and Westphalia as belonging to the 

 Culm or L. Carboniferous group ; and Yon Dechen now defends this 

 determination on stratigraphical grounds, maintaining that the occur- 

 rence of Pentanierus only shows that this genus has a higher range 

 than palaeontologists had previously recognized. E. W. R.
