On a certain Fossiliferous Pebble-band in the “Olive Group“ of the Eastern Salt Range, Punjab

Abstract

Not long ago I received from my friend Dr. H. K. Warth some very interesting specimens, including fossil Conulariæ , discovered by him in the Eastern Salt Range, parts of which region I had examined from his bungalow at the Mayo Salt-mines, and sometimes in his company. His discovery was the subject of a short paper by my self read before the Royal Geological Society of Ireland, an abstract of which appeared in the “Geological Magazine” for March 1886. Almost immediately afterwards, the Records of the Geological Survey of India (vol. xix. pt. 1, 1886) having reached me, I found therein a paper on the same subject by Dr. Waagen, of Prague. The treatment of the matter in this paper and the extent to which its deductions are carried with regard to the geology of the whole Eastern Hemisphere are too important in their bearing upon Salt-Range geology and stratigraphy to be quite passed over by an individual who had the largest part of the task of examining that Range for the Geological Survey of India. So far as the paper now referred to deals with the stratigraphy of the Range, I am in a position to offer opinions the result of direct observation; where it deals with purely pal~eontological matter, I offer none; and where it embraces collateral questions, bearing upon the geology of half the earth, depending upon stratigraphic features of the Range, I claim recognition of the observed facts only so far as my own part in these
