GUIDE TO LOCALITIES 



H^ROUVAL. — Some road-side sand-pits in the sands of the 

 Soissonnais yield a rich assemblage of fossils, as already stated.* 

 They are small exposures and not easy to find. 



MoNTjAvouLT. — At the hamlet called Le Vouast, near a 

 brickyard (the proprietor of which conducted us to the pit), is a 

 good but small exposure of Sables Moyens with many fossils ; 

 Foiarnides concavtis is abundant, colour-marking being preserved. 



Parnes. — One of the richest Calcaire Grossier localities in the 

 Paris basin. The sections are L'Aunaie, Beauves Farm, and 

 Chaudry. Cerithiiim spiratum is one of the remarkable fossils of 

 this locality, but it is rare. 



Chaussy. — A rich locality for Calcaire Grossier fossils, reached 

 by train to Fourges ; the village is two and a-half miles east of 

 the station. 



Le Ruel. — Take train to Chars, walk through Neuilly-en- 

 Vexin and Le Heaulme to Le Ruel. A sand-pit at a road corner, 

 near the inn, has a rich assemblage of fossils, many species being 

 identical with the Barton fauna. It is necessary to dig a trench 

 for the best species; but the innkeeper will do this for a small sum. 

 Melojtge?ia minax is very characteristic and good. 



Of the other sections named it need only be said that they are 

 all good and fossiliferous. 



MOUCHY CENTRE.— (Thirty-four miles N. of Paris.) 



From Gisors, possibly the next best centre is Mouchy, about 

 thirty miles by rail from the former, passing through Beauvais ; 

 or Mouchy can be reached from Paris via Creil on the Chemin de 

 FerduNord. Station, Heilles-Mouchy. Lin at Mouchy, two miles; 

 or at Noailles, four and a-half miles from the station. 



Soon after leaving the station (Heilles-Mouchy) is a section 

 on the left of the road in fossiliferous Sables de Cuise. 



The Calcaire Grossier can be well studied at the points indi- 

 cated ; and the exposures are rich in fossils, those of Mouchy and 

 I*\ay-sous-bois especially.
