Abstract
During his geological survey of the Salt-range in the Punjab, Dr. A. Fleming had opportunities of collecting a considerable number of fossils, which he sent to England in 1849 and 1852, and of which a portion were at the time cursorily examined by M. De Verneuil, myself, and one or two other pakeontologists. Some few of these fossils have been already recorded in a paper by Dr. Fleming, published in the 9th volume of the Quarterly Journal of the Geological Society (1853), also in the Journal of the Asiatic Society of Bengal for 1853, as well as in the same author's excellent 'Report of the Geological Structure and Mineral Wealth of the Salt-range in the Punjab,' printed at Lahore in 1854; and at the author's request I have recently re-examined all the species of JBrachioToda of the Carbonfferous age which he had collected, with the view of completing in this respect the imperfect list published in 1853 *. It will not be necessary to dwell upon the geological features of the Carboniferous rocks of the district, as I could only repeat those details that have been made known in the report and papers above referred to. It will suffice for my present purpose to mention that the fossils occur in several beds differing mincralogically, some being crystalline and very hard, and others argillaceous: a few of the fossils occur in a magnesian limestone; but the same bed may be magnesian in one locality, and at a few miles distance be
