Abstract
The paper descriptive of the series of fossils submitted to me in November 1848 by Prof. Rogers, and read at the meeting of the Society on the 31st of January 1849, has been unfortunately lost; the rough notes taken on the inspection of the fossils have likewise been mislaid, and I am compelled, therefore, in order that the benefit designed by Prof. Rogers to English palæontologists, by bringing over the above collection of rare and valuable instructive fossils, should not be wholly lost, to give now such notes as my restricted leisure will permit of the specimens which have been selected for the subjects of Plates X. & XI.
