70 FOREIGN RELATIONS OF THE 



MARNES D'HAUTERIVE, LANDERON ', LOWER NEOCOMIAN. 



Pycnodus Couloni, Ag. Janira alava, d'Orb. 



Serpula antiquata, Sow. Plicatula Carteroniana, d'Orb. 



[Panopcea Neocomiensis, d'Orb.] Ostrea Couloni, (Defr.), d'Orb. 

 Cardium subhillanum, Leyra. Tombeckiana, d'Orb. 



Opis Neocomiensis, d'Orb. rectangularis, Roem. 



[Perna Mulletti, Desh.j Terebratula tamarindus, Sow. 

 Lima Tombeckiana, d'Orb. 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. 



Pycnodus Couloni, Ag. Ostrea rectangularis, Eoem. 



Sphcerodus Neocomiensis, Ag. Terebratula sella, Sby. 

 Lima Tombeckiana, d'Orb. Moutoniana, d'Arch. 



Pecten Robinaldinus, d'Orb. ,, tamarindus, Sby. 



Hinnites Leymerii, Desk Elasmostoma acutimargo, Roemer. 



Ostrea Couloni (Defr.), d'Orb. Catagma cupuliformis, From. 

 macroptera, Sby. 



The following list also shews considerable relationship between 

 our Upware beds and the Swiss Aptien. 



FOSSILS OF THE APTIEN BEDS, PERTE DU EHONE, ALSO 

 OCCURRING IN THE IRONSAND SERIES. 



Belemnites subfusiformis, d'Orb. Pecten Dutemplei, d'Orb. 



Cyprina angulata, Sby. Pinna Robinaldina, d'Orb. 



Janira Morrisii, P. and R. Pkurotomaria gigantea, Sby. 



Opis Neocomiensis, d'Orb. Serpula antiquata, Sby. 

 Ostrea Couloni, d'Orb. gordialis, Goldf. 



Exogyra conica, Sby. Terebratella oblonga, Sby. 



Panopcea plicata, Sby. Rhynchonellce and Terebratulce. 



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.
