. Bulletin of the British Museum (Natural History), Geology. 0-2. Fig. 19 Tropeothyris sp. Seventeen transverse serial sections through a specimen from the Lower Cenomanian of Julianka, Annopol, Poland. Remarks. Specimens have also been collected from Eastbourne in beds of early Cenomanian age. Terebratula carteri Davidson (1852: 72; pi. 7, fig. 3) may belong to this genus but it differs from the species described here in its uniplicate anterior commissure and slightly more pro- duced umbo. An undescribed specimen which might belong with T. vectis was collected from Pit 19, Loudon Road, Louth,

Seventeen transverse serial sections through a specimen from the Lower Cenomanian of Julianka, Annopol, Poland. Remarks. Specimens have also been collected from Eastbourne in beds of early Cenomanian age. Terebratula carteri Davidson (1852: 72; pi. 7, fig. 3) may belong to this genus but it differs from the species described here in its uniplicate anterior commissure and slightly more pro- duced umbo. An undescribed specimen which might belong with T. vectis was collected from Pit 19, Loudon Road, Louth, Lincolnshire (PI. 9, figs 16-18). It is more regularly oval in outline than the typical form and has a less acutely developed anterior plication. It appears to be closely related to another undescribed species from the Lower Cenomanian of Annopol on the Vistula, Poland (PI. 9, figs 7-9). Serial sections of a specimen from the Phosphate Mine, Julianka, Annopol, Poland (Fig. 19) can be compared to sections through a specimen of Tropeothyris vectis (Fig. 18) and to sections through a specimen from Loudon Road Pit, Louth, Lincolnshire (Fig. 20). Each series has much in common, but more research is necessary before their relationships can be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
