I. Inteoduction. 

 In the Quarterly tTournal of the Geological Society for 1901 (vol. Ivii, 

 pp. 267-84 & pis. x-xi) is a paper by one of us, in collaboration with 

 Prof. C. Lloyd Morgan, dealing with the igneous rocks and the asso- 

 ciated sedimentary deposits of the Tortworth Inlier. The present 

 communication may be regarded as, to some extent, supplementary 

 to the above. Full references to the earlier work on the district 

 having been given in the paper just mentioned, they will not be 

 repeated here. 



The field-work has been carried out by one of us (S. H. R.) ; the 

 identification of the fossils, involving the re-examination of the 

 various public and private collections, by the other (F.R. C. E..). 



The expense of the work, which has involved the digging of a 

 number of trenches and the opening-up of a series of old quarries, 

 has been lightened latterly by means of a grant from the British 

 Association for the Advancement of Science. We are much indebted 

 to the landlords, the Earl of Ducie, Earl Fitzhardinge, and Sir 

 George Jenkinson, Bart., for their kindness in facilitating these 

 excavations. We desire also to thank Mr. J. Harle, Lord Ducie's 

 agent, and Mr. J. Peter, Lord Eitzhardinge's agent, for help and 

 information.
