FOREIGN RELATIONS OF THE 



Marnes d'Hauterive, Landeron 1 , Lower Neocomian. 



Pycnodus Couloni, Ag. 

 Serpula antiquata, Sow. 

 [Panopcea Neocomiensis, d'Orb.] 

 Cardium subhUlanum, Leym. 

 Opis Neocomiensis, d'Orb. 

 [Pema Mulletti, Desh.] 

 Lima Tombeckiana, d'Orb. 



Janira atava, d'Orb. 

 Plicatula C ' arteroniana, d'Orb. 

 Ostrea Couloni, (Defr.), d'Orb. 



„ Tombeckiana, d'Orb. 



,, rectangularis, Roem. 

 Terebratula tamarindus, Sow. 

 „ sella, Sow. 



And from the Pierre jaune (Middle Neocomian) of Landeron, 

 we also have 12 Upware and Brickhill species, these beds further 

 resembling our phosphatic deposits in their. rich sponge fauna. 



Upware Species in the Pierre Jaune. 



Ostrea rectangularis, Roem. 

 Terebratula sella, Sby. 



„ Moutoniana, d'Arcb. 



,, tamarindus, Sby. 



Elasmostoma acutimargo, Roeiner. 

 Catagma cupuliformis, From. 



Pycnodus Couloni, Ag. 

 Sphcerodus Neocomiensis, Ag. 

 Lima Tombeckiana, d'Orb. 

 Pecten Robinaldinus, d'Orb. 

 Hinnites Leymerii, Desh. 

 Ostrea Couloni (Defr.), d'Orb. 

 „ macroptera, Sby. 



The following list also shews considerable relationship between 

 our Upware beds and the Swiss Aptien. 



Fossils of the Aptien Beds, Perte dtt Rhone, also 

 occurring in the Ironsand Series. 



Belemnites subfusiformis, d'Orb. 

 Cyprina angulata, Sby. 

 Janira Morrisii, P. and R. 

 Opis Neocomiensis, d'Orb. 

 Ostrea Coidoni, d'Orb. 

 Exogyra conica, Sby. 

 Panopcea plicata, Sby. 



Pecten Dutemphi, d'Orb. 

 Pinna Robinaldina, d'Orb. 

 Pleurotomaria gigantea, Sby. 

 Serpida antiquata, Sby. 

 „ gordialis, Goldf. 

 Terebratella oblonga, Sby. 

 Rhynchonellai and Terebraticlce, 



Thus, from the comparison of our fossils with the various lists 

 of Swiss species, we gain little knowledge of their exact affinity to 

 any one particular zone in the Swiss series.
