Extract

In order to compare the ammonite sequence in the ibex and jamesoni zones of Pabay, recently described as vitiated by faulting and dykes, with the succession in other areas, it is desirable, first of all, to give full lists of the ammonites collected on the Dorset and Yorkshire coasts by Dr. W. D. Lang and Professor D. M. S. Watson and kindly submitted to the writer for examination.
